SICK Fotoelektrický snímač, řada: W4 LED Blok, výstup: PnP Difuzní IP69K

SICK Series W4 Photoelectric Sensor, IP69K, 100mA Maximum Current - WTB4S-3P2162V

This photoelectric sensor is a diffuse-mode detection device designed for industrial automation and control tasks where non-contact sensing of plastic materials is required. It operates with an LED light source and is built for panel mounting in equipment and machinery, offering a robust stainless construction suitable for demanding environments.

Features & Benefits

• Metal V4A housing provides corrosion resistance and longevity
  IP69K rating enables high-pressure, high-temperature washdowns
  PNP output simplifies integration with standard control logic
  500μs response time supports high-speed detection tasks
  Operates between -30°C and 70°C for wide thermal range tolerance
  30V DC and 100mA limits ensure safe electrical operating margins

**Applications**

• Suitable for detecting plastic components on assembly lines
  Ideal for presence sensing of polymethyl methacrylate parts
  Used with automated packaging machinery requiring fast response
  Can be used for panel-mounted process control in food plants
  Suitable for robotics end-of-arm tooling proximity checks

What materials can it reliably detect?

It reliably senses non-metallic items such as plastics and polymethyl methacrylate using diffuse reflection from the LED emitter.

How does the electrical Interface affect system design?

The PNP switching requires sourcing input logic and is compatible with 30V DC systems with a steady-state current draw up to 100mA.

What environmental cleaning procedures can it withstand?

The enclosure meets IP69K criteria, allowing exposure to high-pressure, high-temperature washdowns without compromising ingress protection.

How quickly will it register changes in the target field?

The device responds in 500μs, making it suitable for applications with Rapid part throughput and short detection windows.

What mounting considerations are necessary for installation?

It is configured for panel mounting and requires secure fastening to maintain alignment and consistent diffuse sensing performance.

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.
