SICK Background Suppression Photoelectric Sensor, Rectangular Sensor, 30 mm → 300 mm, PNP, IP67

SICK W8 Laser Series Photoelectric Sensor, 30V Maximum DC Voltage, 100mA Maximum Current - WTB8L-P2231

This photoelectric sensor is a Compact laser proximity device designed for industrial automation tasks where precise object detection is required. It operates with visible red laser light and is intended for inline integration with control systems via a 4‑pin M8 connector, offering a small-form rectangular plastic package suited to machine-mount environments.

Features & Benefits

• Background suppression laser improves detection of adjacent surfaces
  Response time 250μs enables detection of fast-moving items
  PNP switching output supports direct interfacing with common PLC inputs
  Rated for 10V–30V DC operation for flexible supply arrangements
  IP67 enclosure permits use in wash‑down or dusty production areas
  Adjustment potentiometer allows fine tuning of sensing distance

**Applications**

• Suitable for counting small components on high-speed conveyors
  Ideal for detecting passing items in packaging machinery
  Used for presence checks of small parts in assembly lines
  Can be used for short-range object detection in pick-and-place systems

What connection method is provided for control wiring?

A male M8, 4‑pin connector supplies the electrical Interface for power, switching output and test input.

How does the sensor indicate switching status and stability?

It has two LEDs: one for output switching activity and one green indicator for stability monitoring.

What environmental temperature range can it tolerate during operation?

Operational ambient temperature spans from −10°C to +50°C.

How is the sensing distance adjusted for different target reflectivities?

A four-turn potentiometer combined with a selectable light/dark switching mode permits precise range setting for various surface remissions.
