SICK Background Suppression Photoelectric Sensor, Rectangular Sensor

SICK Series W2 Photoelectric Sensor, IP67, 30V DC Maximum DC Voltage - WTB2S-2P3151

This photoelectric sensor detects small objects using background suppression and is suited to industrial automation and electronics environments. It operates from a DC supply and provides a switched output for integration into control systems. The sensor comes in a rectangular plastic housing with an M8 Interface and a three‑pin Terminal arrangement designed for straightforward mounting in machinery and equipment.

Features and Benefits:

• Pin‑point LED emitter for precise target differentiation
  500 μs response time enabling fast object detection
  PNP output simplifies conventional sourcing input wiring
  IP67 protection allows wash‑down and dusty area operation
  Operates between −25 °C and 50 °C for varied site temperatures
  Maximum 30V DC rating limits voltage exposure to control electronics

Applications

• Suitable for small‑component presence detection on pick‑and‑place lines
  Ideal for conveyor sorting of Compact parts in factories
  Used for end‑of‑travel sensing on automated assemblies
  Can be used for proximity checks on electrical control panels

What current does it draw during normal operation?

The sensor requires up to 50 mA of current during operation, which should be considered when sising power supplies and protection devices.

How is the unit mounted and connected mechanically?

It is secured via a hole mount and connected through an M8 Interface with a three‑pin Terminal arrangement for signal and supply lines.

Which approvals support its use in regulated equipment?

The device carries CE and UL certification and meets EN IEC 63000 requirements for hazardous‑area documentation compliance.

What housing material is used and how does that affect wear?

The enclosure is moulded plastic, providing electrical insulation and resistance to many industrial contaminants while remaining lightweight.
