SICK WT150-P162 Photoelectric Switch Sensor Inline

The SICK WT150-P162 inline photoelectric switch sensor is designed for industrial automation, providing reliable object detection on conveyors, packaging lines, and material-handling equipment. It uses diffuse-reflection sensing with background suppression to maintain stable performance across varying object colors and reflective surfaces, detecting objects up to approximately 400 mm with a visible red light source. The device offers PNP or NPN outputs (model dependent) with light/dark switching selectable, a response time under 1 ms, and a supply voltage of 10–30 V DC in an IP67-rated, industrial-grade plastic housing suitable for harsh environments. It supports standard industrial mounting with cable or variant-dependent connector options, and common replacements for this family include WT150-P460, WT160-P440, and WTB4-3P2261.
