SICK Background Suppression Photoelectric Sensor, Block Sensor

SICK W11-2 Series Photoelectric Sensor, IP66 IP67 IP69K, PNP Output - WTB11-2P2431

This photoelectric sensor detects objects using red light with background suppression, designed for industrial sensing in automation and control systems. It is housed in a robust ABS enclosure that permits use in harsh environments and connects via a four-pin Terminal
the device operates across a wide temperature span for varied factory conditions.

Features & Benefits

• PNP output enabling straightforward Interface with control logic
  Response time 2500μs for moderate-speed detection tasks
  Operates from 0V to 30V for compatibility with common DC systems
  Withstands ambient temperatures from -30°C to 60°C for broad deployment
  IP66, IP67, IP69K protection for resistance to dust and powerful washdowns

**Applications**

• Suitable for presence detection on conveyor lines in food processing
  Ideal for parts counting in mechanical assembly operations
  Used with PLCs for object verification in packaging machinery
  Can be used for position sensing in material handling systems

How is the sensor mounted in tight installations?

It is designed for screw mounting and secures via its block-style housing for compact, stable installation.

What electrical connections are required to operate the unit?

The device uses a four-pin Terminal and requires a DC supply within the specified voltage range and a PNP-compatible input on the control device.

How does it perform in washdown or high-moisture environments?

The enclosure meets IP66, IP67 and IP69K levels, providing ingress protection against dust, water jets, immersion and high-pressure hygiene cleaning.

Are there approvals relevant to industrial use?

The sensor carries recognised UL file approvals which support its acceptance in compliant electrical installations.
