Product Description

​The Omron E3Z-T66 is a compact through-beam photoelectric sensor with a built-in amplifier, offering a sensing distance of up to 15 meters. It operates using an infrared LED light source with a wavelength of 870 nm and features a square-shaped housing measuring 10.8 mm in width, 31 mm in height, and 20 mm in depth. The sensor connects via an M8 4-pin connector and provides an NPN open collector output, capable of handling load currents up to 100 mA with a maximum residual voltage of 2 V. It operates over a power supply voltage range of 12 to 24 VDC and has a response time of 1 ms. With an IP67 rating, the E3Z-T66 is suitable for demanding industrial environments requiring reliable and precise object detection. ​
