MEC extender – and you’re a level higher

We already know, that Switches MEC Unimec switch in up to eight ways and also that they´re available as momentary or alternate (latching). UNIMEC switches feature perhaps only one “disadvantage” – that on the same PCB no other higher components can be used (which would be higher than the switch). If you´re satisfied with the UNIMEC features, but despite that you cannot use them in your application right for ...

Guidelines for reading an optocoupler datasheet

Optocouplers, also known as opto-isolators, are components that transfer electrical signals between two isolated circuits by using infrared light. As an isolator, an optocoupler can prevent high voltages from affecting the side of the circuit receiving the signal. Transferring signals over a light barrier by using an infrared light-emitting diode and a light-sensitive product, such as a phototransistor, is ...
