Sick WT100-2P4439 Miniature Photoelectric Sensor PNP

Miniature Photoelectric Sensor PNP

The Sick WT100-2P4439 is a rectangular photoelectric proximity sensor with a red visible LED light source operating at a wavelength of 632 nm. It offers a maximum sensing range up to 1,200 mm and a defined sensing range up to 750 mm. The unit features a potentiometer for sensing range adjustment and a selectable light/dark rotary switch. It is designed for industrial detection tasks requiring a compact 11 mm x 31 mm x 20 mm housing.

Sustained Operation Within Rated Limits

The sensor operates on a supply voltage of 10 V DC to 30 V DC with a ripple of ±10 % and a power consumption of 30 mA. It provides a PNP switching output with a maximum output current of 100 mA and a switching frequency of 1,000 Hz. The response time is 0.5 ms. Circuit protection includes A, B, and D types. The housing uses ABS/PC/POM plastic with PMMA optics and achieves an IP67 enclosure rating for dust and water protection.

M8 Connector and Temperature Constraints

Connection is made via a male M8 4-pin connector. The device functions within an ambient operating temperature range of –25 °C to +55 °C and can be stored between –40 °C and +70 °C. A mounting bracket BEF-W100-A is supplied for installation. The light spot size reaches Ø 75 mm at a distance of 1,000 mm. Buyers needing a different connector type or wider temperature tolerance should consider other models.
