Compact Photoelectric Sensor for Precision Detection

The Sick WT12L-2B530 is a small rectangular photoelectric proximity sensor that uses background suppression to detect objects at distances between 30 mm and 200 mm. It emits a visible red laser beam focused at 45 mm with a spot size of Ø 0.1 mm, making it suitable for detecting small parts or objects moving at high speeds on automated lines.

Verify Voltage, Connector and Output Compatibility

Your control system must supply 10 V DC to 30 V DC with ripple below 5 Vpp and be able to accept either PNP or NPN switching outputs selectable via the L/D control cable. The sensor connects through a male M12 5-pin connector and draws up to 55 mA, so the power supply and wiring harness must match these electrical requirements.

Stable Operation Under Continuous Industrial Use

With a switching frequency of 2,500 Hz and a response time of 200 µs, the sensor maintains consistent detection during sustained high-speed cycles. The metal housing rated IP67 and IP69K resists dust, water jets and high-pressure washdown, while the Class 2 laser (650 nm) complies with EN 60825-1 for safe long-term operation.

Questions about this item

Does the SICK WT12L-2B530 include mounting hardware or just the sensor body?

The package includes two clamps with screws for installation; no separate bracket is required.

Should I choose the NPN or PNP output version for my PLC input card?

This single unit provides both NPN and PNP outputs selectable via the L/D control cable, so one model covers either wiring style.

What does the 200 mm maximum sensing range mean when the sensor is mounted on a conveyor?

At the 45 mm focal point the laser spot is 0.1 mm, allowing reliable detection of small or fast-moving targets up to 200 mm away.
