SICK WT170-P430 Photoelectric Sensor

The SICK WT170-P430 Photoelectric Sensor is a compact, IP67-rated device that delivers a 10–550 mm sensing range using visible red light, making it suitable for short-to-medium distance object detection on automated lines. Housed in a 12 mm x 37 mm x 28.6 mm stainless-steel form (with variants combining stainless steel and ABS), it uses an M8 4‑pin connector and provides a PNP switched output with selectable light/dark switching via a control cable. Operated from 10–30 V DC with a typical current draw of ~30 mA and supply ripple of ±10%, the WT170-P430 offers a fast response time of ≤ 0.7 ms and a maximum switching distance of 10–400 mm for targets with about 90% reflectivity (DIN 5033). Built for harsh environments, it tolerates ambient temperatures from −25 °C to +55 °C (storage −40 °C to +70 °C), and its optical elements are PC plastic while the housing combines stainless steel and, in some variants, ABS. The part number is 6010198, and the sensor is manufactured by SICK, a recognized leader in industrial sensing technology.
