SICK Background Suppression Photoelectric Sensor, Rectangular Sensor

SICK W24 Series Photoelectric Sensor, IP69K, Metal Housing - WT24-2B440

This photoelectric sensor detects objects using background suppression and is intended for industrial automation tasks where reliable presence sensing is required. Encased in a robust metal housing with an LED light source, it connects via a 4-pin M12 Interface and is suitable for installations requiring threaded or hole mounting in demanding environments.

Features and Benefits:

• Background suppression detection reduces false triggers from backgrounds
  IP69K rating enables high-pressure washdown resistance
  NPN/PNP selectable output simplifies integration with control systems
  30VDC supply and 100mA load capacity supports common control inputs
  Operates from -40 to 60°C for wide ambient temperature tolerance
  500μs response time allows Rapid detection in fast processes

Applications

• Suitable for conveyor part detection where background varies
  Ideal for food-processing lines requiring high-pressure washdown
  Used for pick-and-place operations needing fast switching
  Can be used with PLCs requiring a 4-pin M12 connection
  Suitable for machine frames where threaded mounting is preferred

What connector type is provided for wiring convenience?

A 4-pin M12 connector is fitted to the unit to facilitate standard industrial cabling and quick connection to control terminals.

How does the device cope with hygienic cleaning routines?

The enclosure meets IP69K protection, allowing resistance to high-temperature, high-pressure water jets common in washdown procedures.

Which electrical interfaces does it support for system compatibility?

The sensor offers both NPN and PNP output configurations to match sinking or sourcing input requirements on controllers.

What limits should be observed for electrical supply and load?

The device is designed for a maximum DC voltage of 30V and a maximum current draw or load of 100mA during operation.

How is thermal performance specified for harsh installations?

It is rated to operate across a temperature span from -40°C up to 60°C to suit cold stores and elevated ambient conditions.
