  • Reliable detection up to 12 m with visible red LED
  • Compact 11 × 31 × 20 mm housing fits tight spaces
  • Selectable light/dark switching via 270° potentiometer
  • IP65 enclosure withstands dust and water jets
  • Includes two 304 stainless-steel mounting brackets

Compact through-beam sensor for industrial detection

The Sick WS/WE100-P1439 is a rectangular through-beam photoelectric sensor designed for automation tasks that require reliable object detection across a sensing range of up to 12 metres. Its visible red LED emission and compact 11 mm by 31 mm by 20 mm housing suit confined mounting positions on conveyors, packaging lines or material-handling equipment.

Low power draw with IP65 protection

Operating from a 10 V DC to 30 V DC supply, the sender draws 15 mA and the receiver 20 mA, keeping heat generation minimal in continuous use. The IP65-rated ABS/PC/POM housing resists dust and water jets, while the 0.5 ms response time and 1,000 Hz switching frequency support fast, repeatable cycles without audible noise from moving parts.

Adjustable output and included brackets

A 270° potentiometer and a light/dark rotary switch let installers set the PNP switching mode and sensitivity on site. The 2 m PVC cable with 0.18 mm² conductors simplifies wiring, and two stainless-steel mounting brackets (1.4301/304) are supplied for immediate installation.

Questions about this item

How do I mount the 11 mm x 31 mm x 20 mm rectangular housing and align the 7.2 ° beam?

Use the two included stainless steel brackets (1.4301/304) to fix sender and receiver opposite each other; adjust the 270° potentiometer until the visible red spot (Ø 1,500 mm at 12 m) hits the receiver centre.

What part will need replacement first in a dusty 55 °C environment?

The PVC-jacketed 2 m cable and ABS/PC/POM housing are rated IP65; wipe the PMMA optics periodically, but the cable sheath typically degrades before the electronics.

At what distance does the 1,000 Hz switching rate become unreliable?

The sensing range is specified to 12 m; beyond that the 0.5 ms response time and 15° reception angle increase miss probability, so keep targets within 12 m.
