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 complementary (NO and NC) circuit with NPN (current sinking) or PNP (current sourcing) open collector transistor output.
