Compact photoelectric sensor for industrial

The ZIBOO WTB4S-3N1361 is a miniature photoelectric proximity sensor with background suppression. It operates on 10 V DC to 30 V DC supply voltage and provides an NPN light-switching output rated at 100 mA. The visible red PinPoint LED emits at 650 nm wavelength with a 6.5 mm spot size at 150 mm distance. Detection range spans from 10 mm to 180 mm with a response time under 0.5 ms.

IP67 and IP66 rated housing with fixed cable

The rectangular plastic housing measures 12.2 mm by 41.8 mm by 17.3 mm and weighs 30 g. Optics use PMMA material while the ABS body meets enclosure ratings IP67 and IP66 for dust and water protection. A 2 m PVC cable with 0.14 mm² conductor cross-section and 3.4 mm diameter carries three wires for power and signal. Circuit protection includes A, C and D types. Potentiometer adjustment offers five turns for precise range setting.

Verify voltage, output type

Ensure your control system accepts 10 V DC to 30 V DC input and can read an NPN switching signal. The fixed 2 m cable length may require extension or routing planning in larger cabinets. Operating temperature range covers –40 °C to +60 °C while storage extends to +75 °C. Switching frequency reaches 1,000 Hz for high-speed applications. Buyers needing PNP output or connectorised variants should select a different model.
