Sick WT170-P430 Photoelectric proximity sensor PNP

Sick WT170-P430 photoelectric sensor

The Sick WT170-P430 is a photoelectric proximity sensor with background suppression for industrial detection tasks. It operates on 10 V DC to 30 V DC supply voltage and provides a PNP switching output. The rectangular stainless steel housing measures 12 mm by 37 mm by 28.6 mm and carries an IP67 enclosure rating. This sensor suits automation engineers who need reliable object detection in compact spaces.

Sustained load behaviour

Under continuous operation the sensor draws 30 mA with a ripple tolerance of ±10 %. Its response time is 0.7 ms and the switching mode is selectable via the L/D control cable for light or dark switching. The visible red LED light source maintains consistent performance across the ambient operating range of –25 °C to +55 °C. The stainless steel and ABS housing resists environmental stress in demanding production environments.

550 mm maximum sensing range

The key specification is the sensing range maximum of 10 mm to 550 mm with a defined sensing range of 10 mm to 400 mm. This determines whether the sensor reaches the required detection distance for a given application. Buyers needing longer range or different output types such as NPN should consider alternative models. The M8 4-pin male connector provides the standard interface for integration.
