Sick Fotoelektrik Sensör, Reflektörlü, Algılama Aralığı: 0,01 → 15 m, PNP, Stil: Blok, IP67

SICK W250-2 Series Photoelectric Sensor, IP67, PNP Output Type - WL250-2P2431

This photoelectric sensor is a Compact retroreflective detection device designed for industrial automation and machine-vision environments. It uses a visible red LED to detect reflective targets at short to medium distances and provides a PNP switching output for integration with control systems. The unit is built for panel mounting and has a sealed enclosure suitable for wet or dusty locations.

Features & Benefits

• 0.5ms response time enables very fast object detection
  10–30 V DC operation permits use with common DC supplies
  IP67 enclosure rating allows wash‑down and dustproof installation
  Output current up to 100mA supports direct drive of small loads
  4‑pin M12 connector simplifies quick field connections
  Ambient range −25 to +55 °C supports cold and warm plant sites

**Applications**

• Suitable for conveyor object counting at high cycle rates
  Ideal for presence detection of reflective labels or tape
  Used for part detection in robotic pick‑and‑place lines
  Can be used for access control sensing in packaging machines
  Suitable for mounting on panels for assembly‑line monitoring

How is sensitivity adjusted for different reflectors?

Sensitivity is set via a two‑turn potentiometer with a position indicator to fine‑tune detection thresholds for various reflector types.

What connector orientation options are available for tight installations?

The M12 connector can be rotated by 90° and locked to accommodate vertical or horizontal cable routing.

How does the sensor indicate stable detection conditions?

Two LEDs show stability and received‑light status so engineers can verify alignment and signal reserve during setup.

What protective measures are integrated into the electronics?

The circuitry includes reverse‑polarity protection, interference suppression and over‑current/short‑circuit safeguards depending on the built configuration.
