SICK Background Suppression Photoelectric Sensor, Block Sensor

SICK Series W9 Photoelectric Sensor, IP66, IP67, IP69K, LED Light Source - WTB9-3P2461

This photoelectric sensor detects objects using background suppression and is intended for industrial automation tasks where reliable proximity sensing is required. It is designed for panel mounting and provides electrical switching outputs compatible with common control systems. The unit is built to withstand demanding environments and supports both polarities for flexible connectivity.

Features & Benefits

• LED light source enables fast detection and minimal power draw
  0.333ms response time delivers Rapid object recognition
  Operates from -40°C to 60°C for wide temperature tolerance
  30V maximum supply supports low-voltage control systems
  100mA maximum current allows direct interfacing with small loads
  4-pin M12 Terminal provides secure electrical connection

**Applications**

• Suitable for conveyor object counting in automated lines
  Ideal for washable food processing stations exposed to washdowns
  Used for presence detection on packaging machinery panels
  Can be used for robot cell part verification tasks

What electrical output options are available for integration?

It offers both NPN and PNP switching so it can connect to sinking or sourcing inputs without additional Interface circuitry.

How does the sensor cope with aggressive cleaning procedures?

The housing meets high ingress protection, allowing use in washdown environments and resistance to high-pressure, high-temperature cleaning.

Which materials are used for the enclosure to reduce contamination risks?

The body is formed from Vistal plastic, selected for its smooth surface and suitability in hygienic settings.

What standards relate to its optical safety and substance restrictions?

It conforms to applicable optical safety and hazardous-substance restriction standards as required for industrial deployment.

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.
