Sick Fotoelektrik Sensör, Arka Fon Bastırmalı Algılama Aralığı: 20 → 350 mm, PNP, Stil: Dikdörtgen

SICK Series W9 Photoelectric Sensor, 30V Maximum DC Voltage, 100mA Maximum Current - WTB9M4-3P2261

This photoelectric sensor is a Compact background suppression device designed for industrial sensing tasks where precise detection and environmental resilience are required. Its plastic Vistal housing and block-style form suit panel-mounted installations in automation and electrical systems. The unit employs an LED light source and provides a PNP switching output for integration with control equipment.

Features & Benefits

• Background suppression detection reduces false triggers in cluttered scenes
  PNP output supports direct interfacing with common control inputs
  30V maximum DC rating enables safe operation within low-voltage systems
  100mA maximum current allows predictable drive and load planning
  0.33ms response time permits Rapid detection for high-speed processes
  Withstands -40°C to 60°C operating ranges for varied temperature environments

**Applications**

• Suitable for conveyor item presence detection in automated lines
  Ideal for proximity sensing on panel-mounted control racks
  Used for object sorting where background suppression is needed
  Can be used for machine safety interlocks requiring fast response
  Used with industrial controllers needing a 4-pin M8 connection

What connection format does it use for wiring?

It employs a 4-pin M8 connector for straightforward sensor-to-cable termination.

How does the enclosure cope with washdown and dust?

The construction meets IP66, IP67 and IP69K ingress ratings, permitting resistance to dust, high-pressure cleaning and temporary immersion.

Which approvals confirm suitability for compliant installations?

It carries UL NRKH.E181493, CE and cULus approvals for recognised regulatory conformity.

What mounting style is required for installation?

The device is intended for panel mounting to integrate neatly into control panels and equipment frames.

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.
