SICK Background Suppression Photoelectric Sensor, Rectangular Sensor

SICK W16 Series Photoelectric Sensor, IP66/IP67/IP69, 30V Maximum DC Voltage - WTB26I-24161120A00

This photoelectric sensor is a background suppression proximity device designed for industrial automation. It detects objects using an infrared LED beam and can be configured via IO-Link or a BluePilot teach control. The unit is intended for use where selective object detection is required and operates across a wide ambient temperature range.

Features & Benefits

• 2.3ms IO-Link cycle time enables Rapid parameter updates
  less than or equal to 500μs response time supports high-speed switching
  Push-pull outputs handle PNP and NPN wiring configurations
  Adjustable suppression threshold for 180mm–2000mm range
  LED indicators provide clear status and teach feedback
  Protection to IP66 IP67 IP69 allows wash-down compatibility

**Applications**

• Suitable for conveyor object detection requiring background suppression
  Ideal for pick-and-place systems with varying object colours
  Used with automation masters supporting IO-Link V1.1
  Can be used for machine-guarding signal integration
  Suitable for food-industry areas requiring high-pressure cleaning

What supply voltage must I provide for operation?

The sensor runs from 10V DC to 30V DC with a maximum ripple of 5 Vpp.

How is the output wired for control systems?

It uses a 4-pin M12 male connector with configurable pin functions and push-pull switching, and each output is protected against reverse polarity and short circuit.

What detection distances can I expect for different reflectivities?

The teach-adjustable sensing threshold covers from 30mm minimum up to 2000mm maximum, with recommended operation between 200mm to 800mm for best performance.

How robust is the unit mechanically and environmentally?

The housing is a VISTAL® plastic construction with PMMA front screen, rated for shock and vibration and operable between −40°C to +60°C.

Can I perform Advanced logic or diagnostics remotely?

Yes, IO-Link provides process data, device configuration, Smart Task logic functions and diagnostic status including quality of teach.
