Sick WT12-2P450 Proximity Sensor
The Sick WT12-2P450 is a photoelectric proximity sensor with background suppression designed for industrial detection tasks. It uses visible red LED light to sense objects at distances from 80 mm to 800 mm. The rectangular metal housing measures 15 mm by 49 mm by 41.5 mm and carries an IP67 enclosure rating. This sensor suits electricians and automation engineers needing reliable presence detection.
Installation Requirements
Verify that your control system provides a 10 V DC to 30 V DC supply with ripple below 5 Vpp and can accept a PNP switching output. The sensor connects via a male M12 4-pin connector and draws up to 30 mA. Ensure the mounting location stays within the –40 °C to +60 °C operating temperature range and allows space for the potentiometer adjustment. The UL file numbers are NRKH.E181493 and NRKH7.E181493.
Sustained Operation Behaviour
Under continuous use the sensor maintains a response time of 330 µs and supports light or dark switching modes. The zinc diecast housing and PMMA optics resist environmental stress across the –40 °C to +75 °C storage range. Power consumption remains steady at the rated 30 mA level during extended cycles. The IP67 rating protects internal electronics from dust and water ingress over long shifts.

Questions about this item
What comes in the box with the WT12-2P450 sensor and do I need a separate cable?
The sensor has an M12 4-pin male connector; a matching M12 cable or cordset must be purchased separately.
Which sensing range should I select for the WT12-2P450?
The sensor covers 80 mm to 800 mm with background suppression; choose it when you need that exact window.
What does the 330 µs response time mean on a production line?
The output switches within 330 µs, so the sensor detects objects moving at high speed without missing cycles.
