ET Series Through-Beam Sensors Carlo Gavazzi ET series 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 complementary (NO and NC) circuit with NPN (current sinking) or PNP (current sourcing) open collector transistor output. Long 20 m Range
Adjustable sensitivity
Modulated infrared light
Make and break switching functions, NPN, PNP (200 mA)
LED-indication for power supply ON (emitter) and target detected (receiver)
Supply voltage: 10 to 40 VDC
Heavy duty M18 metal housing, IP 67
