SICK WTB250-2P2441 6044682 Photoelectric Proximity Sensor PNP 500mm

SICK WTB250‑2P2441 is a photoelectric proximity sensor with background suppression, designed for reliable object detection in industrial automation. It emits visible red light to distinguish a target from its background, minimising false triggers. The compact rectangular housing (65 × 20 × 43.9 mm) is made of reinforced ABS plastic rated IP67 and includes a status indicator for on‑axis commissioning.

Applications:

• Product presence and position detection in packaging lines

• Object detection on material handling and logistics conveyor systems

• Part positioning in automated assembly and sorting machinery

• Quality control for food, beverage and automotive production lines

Core Specifications:

• Sensing range: 150 mm … 500 mm (adjustable with 2‑turn potentiometer)

• Light source: LED, visible red light

• Supply voltage: 10 … 30 V DC

• Output type: PNP, light/dark switching selectable

• Output current: ≤ 100 mA

• Response time: ≤ 3 ms

• Switching frequency: 160 Hz

• Connection: M12 male connector, 4‑pin

• Enclosure rating: IP67 (IEC 60529)

Advanced Specifications:

• Background suppression: activates only when the object is closer than the set background

• Adjustment: 2‑turn potentiometer with positioning indicator for precise range setting

• Circuit protection: overload, reverse polarity and short‑circuit protected

• Housing material: reinforced ABS plastic

• Optical window material: PMMA

• Dimensions (W × H × D): 20 mm × 65 mm × 43.9 mm

• Weight: approx. 40 g

• Ambient operating temperature: –25 °C … +55 °C

• Storage temperature: –40 °C … +75 °C

System Integration:

• Belongs to the SICK W250‑2 series of compact photoelectric sensors.

• Mount the M12 male connector to a standard M12 4‑pin female cable.

• Wire pin 1 to 24 V DC positive, pin 3 to 0 V DC, and pin 4 to a PNP PLC input. Select light‑on or dark‑on mode via the control cable.

• Adjust the sensing threshold by turning the potentiometer. The yellow output LED lights when the sensor switches.

• A bracket is normally supplied for easy mounting on walls or struts.
