SICK WS/WE100-2P4439 W100 Through-Beam Photoelectric Sensor Set

WS/WE100-2P4439 is a SICK W100 through-beam photoelectric sensor set (part no. 6052368): a sender and a receiver that face each other, with the output changing when an object cuts the beam. Through-beam is the principle with the longest range and the highest reserve, because the light only travels one way. The data sheet gives a sensing range of 0 m … 33 m. Output: PNP, light/dark switching; connection: Male connector M8, 4-pin.

Why a W100 through-beam set suits long and narrow gaps

Because the receiver looks straight at the sender, a through-beam pair is the first choice for small, transparent-edged or dark objects that other principles struggle with, and for long gaps such as doorways, conveyor gaps and pallet entries. The price is two devices to mount and align, with wiring to both; the table lists what the set contains.

Light source: LED, visible red light, light spot Ø 850 mm (12 m). Adjustment: potentiometer, 270° (Sensitivity). Response time ≤ 0.5 ms, switching frequency 1,000 Hz.

Technical specifications

Type code WS/WE100-2P4439 and part number 6052368

Treat 6052368 as the catalogue key for this WS/WE100-2P4439 set: the prefix WS/WE100 names the line, the digits describe the pair, and a single number covers sender and receiver together. If you need one half only, ask before ordering, because spare halves are listed separately by SICK.

Alignment and wiring of the WS/WE100-2P4439 pair

Power both units from 10 V DC … 30 V DC; the receiver carries the output. Fix them opposite each other on rigid supports, switch on, and turn the sensitivity adjustment while watching the indicator until the beam is received with margin. Enclosure rating IP67; ambient range –25 °C … +55 °C. Compare the input type of your controller (PNP versus NPN) and the light/dark setting before putting the line into service, and keep lenses clean, because a dirty window reduces the margin of the longest beams first.
