SICK Background Suppression Photoelectric Sensor, Rectangular Sensor, 4 mm → 500 mm, PNP, IP66, IP67, IP68, IP69K

SICK Series W4 Photoelectric Sensor, Stainless Steel Housing, IP66, IP67, IP68, IP69K - WTB4S-3P2262V

This photoelectric sensor detects objects using background suppression and is engineered for industrial sensing tasks. It operates with a pin‑point LED light source and is housed in a rectangular stainless‑steel enclosure, intended for threaded mounting and harsh‑environment installations where precise object discrimination is required.

Features and Benefits:

• PNP output provides easy integration with control logic
  30 VDC maximum allows safe low‑voltage system connection
  100 mA maximum current supports typical input circuits
  500 μs response time enables fast detection in dynamic processes
  Operating range from -30 to 60 °C suits elevated temperature environments
  IP66, IP67, IP68, IP69K protection permits wash‑down and immersion use

Applications

• Suitable for detecting methyl methacrylate components on conveyors
  Ideal for plastic part presence checks on assembly lines
  Used for proximity sensing where stainless housings are required
  Can be used for wash‑down food or chemical processing stations
  Suitable for integration with M8 connector cabling in automation panels

What connector arrangement does it use for wiring?

It employs a 4‑pin M8 connector Interface for signal and supply connections.

Which approvals cover its suitability for industrial deployment?

It meets CE and UL certification standards relevant to industrial electrical equipment.

How does the housing material affect installation choices?

The stainless‑steel construction increases resistance to corrosion and mechanical wear, enabling use in harsher surroundings.

What mounting option is provided for fixation?

The sensor is designed for threaded mounting to secure it in position within sensor brackets or panels.
