SICK WL100-P1439 Miniature Sensor

The SICK WL100-P1439 is a new miniature photoelectric retro-reflective sensor with dual lens optics. It operates on a 10 V DC to 30 V DC supply and provides a PNP switching output with selectable light or dark switching. The red LED light source emits at a 632 nm wavelength with a sensing range up to 7.2 m. A 2 m PVC cable and mounting bracket are included in the box.

Ideal for Automated Detection Tasks

This sensor suits automation engineers who need a compact rectangular housing measuring 11 mm x 31 mm x 20 mm for presence detection in tight spaces. The IP67 enclosure rating handles dust and temporary immersion in industrial environments. Buyers who require a different output logic such as NPN or a connectorised connection type instead of a flying lead cable should look at alternative models.

7.2 m Maximum Sensing Range

The decisive specification is the maximum sensing range of 7.2 m using the supplied P250 reflector. The effective operating range reaches 5.5 m with a 0.5 ms response time and 1000 Hz switching frequency. Sensitivity is adjusted via a potentiometer and the visible red light produces a 280 mm light spot at 4 m distance.

Questions about this item

How far can the 7.2 m sensing range actually detect in a real installation?

The sensor reaches 7.2 m with a reflector under ideal conditions; the practical sensing range with the supplied P250 reflector is 0.01 m to 5.5 m.

What does the 10 V DC to 30 V DC supply voltage range cap in practice?

The sensor operates from 10 V DC to 30 V DC with ±10 % ripple, draws 30 mA, and the PNP output switches up to 100 mA at 1,000 Hz.

Will the 11 mm x 31 mm x 20 mm housing fit on standard DIN rail or need a special bracket?

The rectangular ABS/PC/POM housing measures 11 mm x 31 mm x 20 mm and ships with a BEF-W100-A mounting bracket for direct installation.
