IEC connector is the common name for a set of thirteen power connectors (called the connector specifications) and thirteen outlet panels (called input) specification defined by IEC 60320 (formerly IEC 320) of the International Electrotechnical Commission ( IEC). When used without other qualifiers, "IEC connector" usually refers specifically to the C13 and C14 connectors.

The Bowens standard is a standard widely used in photography, mainly used for joining softbox or umbrella to any type of flash, notable for having 3-point hitch.

In IEC connector or cable with a base (usually plastic) and a plug to connect to the socket (plug), if we put these two things we would get the named SCHUKO is the overall connector. The schuko not determine the type of connector. It would be determined by the specification of the International Electrotechnical Commision (IEC). We leave a small sample of Schukos internationally.

When carrying out an electrical installation or electrical circuit several factors must be taken into account, one of them is the selection of the appropriate cable. According to the installation and the use of the same we can find different diameters that support different loads. The cable section will also help us not to overheat our installation, since the larger the section, the greater the thermal resistance.
In the following table poWe can see the corresponding load supported for the different sections of cables.

The photoelectric sensors are those sensors that act by closing or opening the circuit depending on the light intensity they receive.
The system consists of an emitter system in charge of emitting light and a receiver system, in charge of managing its function according to the light received.
We can find several types of photoelectric sensors although we can divide them into several more generic groups, barrier photocell (A), Self-reflective (B) and reflective with reflector (C).

The barrier sensor is possibly one of the most used sensors due to its simplicity of use, easy installation and reliable operation.
Its operation is simple, the transmitter is placed in line with the receiver being one in front of the other. Thanks to this distribution external aspects such as dirt, dust, humidity affect to a lesser extent its operation.
This type of barrier sensors have a range ofAnd much greater detection to the rest, it is possible to say that being an emitter and a receiver this type of sensors are not able to detect color in objects as other sensors can make and it is necessary to take into account that these sensors emit a light that is captured By the emitter, if when crossing the barrier we do with a transparent or translucent object will not be activated, as the beam of light will get through the object, therefore alone andS valid for objects with a high degree of opacity.
These types of sensors are widely used in security and automation systems, for example opening or closing a barrier or door, activating an alarm, etc.
When faced with, the emitter emits a beam of light to the receiver, if the receiver is receiving the light beam it will be in standby mode to act. When an object passes between the sender and the receiver, cutting the view directlyAnd leaving the receiver without receiving the light this will activate the function for which it is programmed, for example in a security door, the door remains closed while the light beam is received by the receiver, if a person passes between the two transmitters The beam and light will be interrupted by the body of the person, so that the sensor will act by opening the door.

This is one of the most economical models of detectors by photocell, but against is one of the least recommended in situations with high humidity or places with a lot of dust or dirt. The reception distance is also shortened as opposed to the barrier, so they do not have as much detection range. This factor is directly linked to the color of the object, since the light emitted must bounce on it, it will not haveThe same index of reflection an object of black color (that absorbs the light) to a white object (that bounces the light), therefore, objects of light colors will be better detected with a self-reflecting photocell.
This type of sensors unlike those of barrier, its emitter and receiver are in a single device. The emitter emits light on the object, when light reaches the object it bounces and is received by the receiver, qYou will be in charge of executing the action, like stopping a tape, adding a unit, triggering a mechanism, etc.
As it is a single device its installation is minimized, since it is only necessary to feed a point, unlike the barrier that are two points. They are ideal for installations where it is complicated or there is no space to place the receiving device.
This type of photocells can be divided into 3 groups,Standard or self-reflecting photocells, background suppression and autoreflective foreground photocells (FGS, Foreground suppression)

• Self-reflective or non-suppressed photocells (the standards) are those whose detection distance is affected by the color of the detected object. As a result of this small inconvenience,Have improved these sensors by creating two variants, with background suppression and foreground suppression.
• Self-reflective or suppressed photocells work in the same way as the previous ones, but also use several triangulations of the light to calculate the exact position in which the object is. Thanks to these triangulations the sensor is able to ignore any object that may be behind and pUeda interfere in the detection, in such a way that they are not so affected by lighter colors, shapes or brightness of the object.
• Self-reflective photocells with foreground suppression are those that work just like background suppression but focus on the background surface, adjusting the detection zone at that distance. Basically, what the sensor does is focus on the background and will detect any object thatIs placed on said background, for example, is the system used for the detection of objects on a conveyor belt or other surface.

As it is common in installations we can find a standard of colors in the electric cables.

These regulations help at a glance to understand the connection and the resolution of possible faults or failures.

Below we attach the color/cable relation for electrical installations.

1. The ground wire can be identified in several ways:
• Green cable.
• C cablegreen smell with a yellow line.
• Cable without insulation.
2. The neutral wire will be blue.
3. The phase cable can be identified in several ways:
• Any color different from neutral or earth.
• Black insulation.
• Brown isolate.
• Gray insulation.

The insulating or insulating tape is a fundamental element when making a repair or performing an electrical installation. The insulating tape will help us to protect and insulate the electrical cables from possible crossings or contacts between them or with other elements, guaranteeing that the connection is well insulated avoiding possible short circuits.
Its use is very simple, since being a flexible material allows us to apply it with comfort.
To achieve a perfect union, it is recommended that we wrap the tape covering half the cable and half over the joint, stretching the tape slightly while rolling obliquely.

• For the ground wire, colored insulation tape will be used:
• Green.
• Green with a yellow line.
• For the neutral cable, blue insulating tape will be used.
• For the cable the phase isYou can use any other color:
• Any color different from neutral or earth.
• Black insulating tape.
• Brown insulating tape.
• Gray insulating tape.

VAC would be the abbreviation of Volt Altern Current which would be translated Volts of alternating current. The difference between VDC is that its sinusoidal oscillation achieving a more efficient energy transmission.

The alternating current is the energy that we receive in our homes, it is generated in the power plants by means of alternators.

The intensity of this type of current varies with time, and changes direction 50 times throughsecond (50hz). The generated voltage changes in the form of sine wave so it is not constant.

ABS material (acrylonitrile butadiene styrene) is a type of thermoplastic that is very resistant to impact or shock.

Its applications are several, for example is a material widely used in the manufacture of interiors or components of cars such as moldings, as well as in products for domestic use such as toys, tools, housings of electrical devices etc.

One of its most important characteristics is its great tenacidad in almost all types of temperatures.

Being a very hard material has good chemical resistance, low water absorption and high resistance to abrasion, where other types of plastics would be more brittle.

This type of material is becoming very famous in the particular field and widely used due to the great growth in the sales of domestic 3D printers, the main printing raw material.next to the PLA.

Identification of ABS
Parts that are made of ABS material must be marked in accordance with ISO 11469 (DIN 58840).
