Miniature Photoelectric Sensor PNP
The Sick WLG4-3F2132 is a rectangular retro-reflective sensor measuring 16 mm by 39.5 mm by 12 mm. It operates on 10 V DC to 30 V DC supply voltage with a PNP dark-switching output rated at 100 mA. An M8 3-pin connector provides the electrical connection. The housing uses ABS plastic with PMMA optics and weighs 30 g.
PinPoint LED and Teach-In Adjustment
A visible red PinPoint LED emits at 650 nm wavelength, producing a 75 mm light spot at 1.5 m distance. The single teach-in button simplifies setup for detecting transparent objects. Switching frequency reaches 1,000 Hz with a response time under 0.5 ms. The angle of reception is approximately 30 degrees.
Suited for Compact Automation
This sensor suits applications requiring a small footprint and reliable detection of clear materials within a 0.02 m to 3.5 m sensing range. Its IP67 and IP66 ratings support harsh environments from –40 °C to +60 °C. Buyers needing through-beam or diffuse modes, longer range, or different output logic should consider alternative sensor types.

Questions about this item
Will the PinPoint LED or M8 connector need replacement after continuous use?
The PinPoint LED is solid-state with no rated replacement interval, and the M8 3-pin connector is rated for repeated mating cycles; neither has a scheduled maintenance interval in the specifications.
What limits sensing range first when the sensor runs continuously at 1,000 Hz?
The 0.5 ms response time and 1,000 Hz switching frequency set the timing limit, while the 4.5 m maximum and 3.5 m practical sensing ranges define the distance limit under sustained operation.
How much heat and noise does the sensor produce when powered at 30 V DC all day?
Power consumption is 20 mA at up to 30 V DC with no moving parts, so audible noise is absent and heat dissipation stays low within the –40 °C to +60 °C ambient operating range.
