SICK Background Suppression Photoelectric Sensor, Rectangular Sensor

SICK W150 Series Photoelectric Sensor, 30V Maximum DC Voltage, 100mA Maximum Current - WT150-P460

This photoelectric sensor is a Compact background suppression device designed for industrial detection tasks in automation and machine control. It uses visible red LED illumination and selectable light/dark switching to detect objects without reference contrast, and connects via a 4‑pin M8 male connector for straightforward integration into control systems.

Features & Benefits

• 0.5ms response time enabling high-speed detection
  100mA output current supporting direct actuator drive
  10–30 V DC supply for wide voltage compatibility
  IP67 enclosure rating allowing washdown and dustproof use
  Potentiometer adjustment for precise sensing range control
  ABS and polycarbonate housing providing impact-resistant protection

**Applications**

• Suitable for conveyor object presence detection in packaging lines
  Ideal for part counting at high switching frequencies
  Used for positioning checks on pick‑and‑place equipment
  Can be used for material detection where space is restricted
  Suitable for integration with PLC inputs via PNP switching

How is switching polarity or behaviour changed on the device?

The switching mode can be toggled between light and dark operation using an L/D control cable to suit different sensing tasks.

What environmental temperatures can it operate within?

It functions reliably from −25°C up to +55°C for typical industrial ambient conditions.

What indicators aid alignment and diagnostics during setup?

A green LED shows signal stability and an Orange LED indicates when the output is Active to assist commissioning.

What mounting and connection accessories are supplied?

A bracket is included for mounting and the unit is fitted with a male M8, 4‑pin connector for electrical connection.

How does optical performance vary by target reflectance?

The sensing range depends on target reflectivity, reaching up to 100mm on highly reflective surfaces with an approx. 5° beam dispersion.
