Industrial Photoelectric Sensor
The Sick WT24-2B210 is a compact photoelectric proximity sensor designed for industrial automation and material-handling tasks. It uses background-suppression technology to detect objects reliably across a sensing range of 100 mm to 2,500 mm. The rectangular zinc-diecast housing measures 27 mm by 87.5 mm by 65 mm and carries an IP67 enclosure rating for harsh environments.
Sustained Detection Performance
Infrared LED emission creates an 80 mm light spot at the maximum distance, allowing stable object detection without reflector alignment. The potentiometer adjustment lets operators set the precise switching point for consistent operation over long production runs. Switching frequency reaches 1,000 Hz with a 500 µs response time, supporting high-speed conveyor or packaging lines.
Thermal and Electrical Characteristics
The sensor operates on a 10 V DC to 30 V DC supply with under 5 Vpp ripple and draws 50 mA. Selectable NPN or PNP output delivers up to 100 mA switching current in light-on or dark-on modes. Protection class II circuitry includes reverse-polarity and short-circuit safeguards. Ambient operating temperature spans –40 °C to +60 °C, while storage extends to +75 °C.

Questions about this item
How much heat does the WT24-2B210 generate when running continuously on a 24 V DC supply?
The sensor draws 50 mA from a 10 V DC to 30 V DC supply with ripple below 5 Vpp, and its metal zinc-diecast housing dissipates heat within the –40 °C to +60 °C operating range.
What power supply and wiring must I already have to install the WT24-2B210?
You need a 10 V DC to 30 V DC source capable of 50 mA, an M16 cable gland for the terminal connection, and a load that accepts NPN or PNP output up to 100 mA.
Will the WT24-2B210 work alongside older 24 V DC relay logic and contactors in the same cabinet?
Yes, it operates on 10 V DC to 30 V DC with selectable NPN or PNP light/dark switching, 500 µs response time and 1,000 Hz switching frequency compatible with legacy relay timing.
