SICK Retroreflective Photoelectric Sensor, Rectangular Sensor

SICK W280-2 Series Photoelectric Sensor, IP67, 30V Maximum DC Voltage - WL280-2P2431

This photoelectric sensor is a Compact retroreflective LED device designed for industrial sensing tasks. It detects objects by measuring reflected light and is intended for use where robust, Compact optical detection is required in automation, electrical and mechanical systems. The unit connects via a 4-pin M12 Interface and is supplied with a mounting bracket and reflector to support straightforward installation.

Features & Benefits

• 10V–30V DC supply supporting common control voltages
  PNP switching gives direct sourcing output for PLC inputs
  less than or equal to 0.5ms response assists high-speed detection requirements
  IP66 and IP67 ratings enable use in harsh environments
  −25 to +55 °C range maintains operation across wide temperatures
  100mA output current supports typical sensor loads

**Applications**

• Suitable for presence detection on conveyors in factories
  Ideal for object counting in packaging machinery
  Used for alignment checks with reflective targets in assembly lines
  Can be used for access-control sensing where sealed devices are needed
  Suitable for integration with PLCs via M12 connector in control cabinets

What connection options are available for integration?

It uses a male M12, 4-pin connector compatible with standard sensor cables and connectors for straightforward wiring to controllers.

How is sensing distance adjusted on-site?

A built-in potentiometer allows the sensing range to be tuned to different reflector types and target distances.

Which indicators assist commissioning and diagnostics?

Dedicated LEDs show stability of the received signal and the current light-beam status to aid setup and troubleshooting.

What mechanical parts are supplied for mounting?

A bracket and a rectangular reflector are included to provide a ready-to-mount retroreflective arrangement.

How does the device handle electrical disturbances?

The sensor includes multiple circuit protections such as reverse-polarity protection, interference suppression and output short-circuit protection to reduce wiring-related faults.
