.. Photoelectrics Through-beam Type ET 1820 DC, Nickel-plated Brass Housing - - - - - - - - Range: 20 m Adjustable sensitivity Modulated infrared light Make and break switching functions, NPN, PNP (200 m A) LED-indication for power supply ON (emitter) and target detected (receiver) Supply voltage: 10 to 40 VDC Heavy duty M18 metal housing, IP 67 Cable and plug versions Product Description The ET1820 is a family of general purpose through-beam sensors in an industrial standard M18 nickel-plated brass housing for heavy duty applications. They are useful for simple applications where a basic sensor provide adequate sensing performance. The sensors are easy to adjust with a 270° single turn potentiometer. The output is a 4-wire plementary (NO and NC) circuit with NPN (current sinking) or PNP (current sourcing) open collector transistor output.
