SICK Background Suppression Photoelectric Sensor, Block Sensor

SICK W11-2 Series Photoelectric Sensor, IP66, IP67, IP69K, PNP Output - WTB11-2P2461

This photoelectric sensor detects objects using background suppression and is designed for industrial automation tasks. It has a block-style housing MADE from ABS and is suited to panel mounting with a 4-pin M12 terminal. The sensor uses an LED light source and provides a PNP switching output for integration with control systems.

Features & Benefits

• Detects objects while ignoring background for reliable sensing
  LED illumination for consistent detection performance
  Fast response time of 2.5ms for high-speed processes
  Operates from low-voltage DC up to 30V to suit control circuits
  Low operating current of 30mA for efficient power use
  Wide temperature range from -30 to 60°C for varied environments

**Applications**

• Suitable for part presence detection on assembly lines
  Ideal for conveyor object separation and counting
  Used for pick-and-place verification in robotic cells
  Can be used for material handling gate sensing in factories
  Suitable for integration into panel-mounted control cabinets

What electrical connection does it require?

It connects via a 4-pin M12 Terminal and provides a PNP switching output compatible with common industrial input modules.

How resistant is the enclosure to harsh cleaning and washdown?

The ABS housing carries high ingress protection ratings including IP66, IP67 and IP69K for protection against jets, immersion and high-pressure/temperature washdowns.

What response behaviour can be expected in fast-cycle operations?

With a 2.5ms response time and LED illumination, the sensor supports Rapid detection cycles suitable for many high-throughput applications.

What operating temperatures are supported for cold storage or heated panels?

It functions across a broad span from -30 to 60°C, permitting use in chilled environments and near warm machinery components.

Notes

For retro-reflective sensors a suitable reflector is required.
For PL80A, PL30A & C110 reflectors see stock nos. 265-2776, 265-2760 & 265-2748 respectively.
