Industrial Fiber-Optic Sensor

The Sick WLL170-2P330 is a rectangular fiber-optic sensor designed for industrial automation and electrician tool applications. It operates on a 10 V DC to 30 V DC supply voltage with a visible red LED light source at 660 nm wavelength. The unit features a PNP switching output with light/dark switching selectable via a selector switch. It is supplied with a BEF-WLL170 mounting bracket and an M8 3-pin connector.

2000 Hz Switching Frequency

The sensor delivers a switching frequency of 2,000 Hz with a response time of 250 µs, making it suitable for high-speed detection tasks. It offers a maximum sensing range of 0 mm to 4,000 mm in through-beam mode and up to 700 mm in proximity mode. A 10-turn potentiometer allows precise sensitivity adjustment while a selectable off-delay of 40 ms provides timing control for the output signal.

Suits Fast Automation Lines

This sensor suits engineers needing a compact, IP66-rated photoelectric switch for rapid object detection on conveyors or packaging equipment. The 10 V to 30 V DC range fits standard industrial power supplies and the M8 connector enables quick installation. Buyers requiring an NPN output type or analog measurement capability should look at alternative sensor models.

Questions about this item

What does the 2,000 Hz switching frequency mean when the sensor is installed on a production line?

It allows the sensor to detect up to 2,000 objects per second, so fast-moving parts on conveyors or packaging machines are reliably counted without missed signals.

The sensor uses a 3-pin M8 connector — what voltage range and output type does that interface support?

The M8 connector carries a 10 V DC to 30 V DC supply and provides a single PNP switching output rated at 100 mA maximum.

What mounting hardware is included and how much space does the sensor need?

A BEF-WLL170 mounting bracket is supplied, and the rectangular housing measures 10.5 mm wide by 35.5 mm high by 83.7 mm deep.
