The delivery program includes quasi-embeddable devices. Varying from the standard, the series 500 offers however greater operating distances (2.2 to 3 times the standard values).
The devices are available in 3-wire DC NPN and PNP executions, in either N.O. or N.C. configuration; a LED output state indicator is standard. In addition, all the important protection functions are built in, such as short-circuit and overload protection, full polarity reversal protection, induction protection, EMC protection, power-on reset, etc.
