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 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 • Cable and plug versions Product Description Ordering Key ET 18 20 NPA S-1 The ET1820 is a family of gen- eral purpose through-beam sensors in an industrial stan- dard M18 nickel-plated brass housing for heavy duty appli- cations. They are useful for simple applications where a basic sensor provide adequate sensing performance. The sen- sors are easy to adjust with a 270° single turn potentiometer. The output is a 4-wire comple- mentary (NO and NC) circuit with NPN (current sinking) or PNP(current sourcing) open collector transistor output.
