SICK Diffuse Photoelectric Sensor, Block Sensor, 30 mm → 175 mm, PNP, IP66, IP67, IP69K

SICK W12 Series Photoelectric Sensor, IP66, IP67, IP69K - WTF12-3P2431

This photoelectric sensor is a Compact diffuse-detection device designed for industrial sensing tasks where non-contact material recognition and presence detection are required. Built for panel mounting, it employs an LED light source and a block-style housing to perform short-range detection of plastics and methyl methacrylate in automated systems. The unit operates across a broad temperature range and is intended for use in demanding production and assembly environments.

Features & Benefits

  PNP output delivers easy integration with control logic
  330 μs response time supports Rapid detection cycles
  Metal housing offers mechanical robustness in harsh sites
  Operates from -40 to 60 °C for wide ambient tolerance
  Screw terminals facilitate secure electrical connections

**Applications**

• Suitable for presence detection on automated plastic assembly lines
  Ideal for material handling where methyl methacrylate is processed
  Used with control panels requiring panel-mount sensors
  Can be used in food-processing lines requiring high ingress protection
  Suitable for robotics end-of-arm sensing in short-range tasks

What voltage and current limits should be observed when wiring it?

The sensor operates with a maximum DC voltage of 30V and a maximum current draw of 45 mA, so ensure the supply and input circuitry remain within these limits.

How does the device perform where Rapid switching is needed?

With a response time of 330 μs it supports fast switching requirements typical in automated cycle operations.

What approvals support installation in industrial equipment?

It carries CE and UL recognitions that relate to conformity and safety for industrial applications.

Which output configuration is provided for interfacing with automation controllers?

The unit uses a PNP switching output suitable for sourcing inputs on PLCs and discrete control modules.

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.
