Sick WTB2S-2P3110 Фотоэлектрический датчик

SICK W2S-2 Series Photoelectric Sensor, Background Suppression Detection Type, IP67 - WTB2S-2P3110

This photoelectric sensor is a Compact optical proximity device designed for detecting small items in industrial environments. It uses visible red light with a pinpoint LED emitter to distinguish objects from their background and is intended for panel mounting in automation and electronics applications where precise short-range detection is required.

Features & Benefits

• Background suppression from 20mm ensures reliable object discrimination
  Visible pin-point LED produces a 2mm spot for small-target sensing
  Response time 0.4ms supports high-speed switching up to 1,200Hz
  PNP switching output allows easy integration with common control systems
  IP67 enclosure rating permits use in wet or dusty locations
  Operating range 3mm to 15mm handles small-part detection reliably

**Applications**

• Suitable for part presence detection on high-speed pick-and-place lines
  Ideal for small-object sorting where precise edge detection is required
  Used for position sensing in Compact automation assemblies
  Can be used for quality inspection stations detecting tiny components
  Suitable for conveyor-fed electronics production for component counting

What supply voltage is required for operation?

It operates from 10V DC to 30V DC with low ripple tolerance and a typical current draw of 20mA without load.

How is the device connected electrically?

Connection is via a 3-pin M8 connector on a 200mm PVC cable with straight M8 mating options available.

What environmental temperature range can it withstand?

It is rated to function between −25°C to +50°C and can be stored between −40°C to +75°C.

How is the sensor protected against electrical faults?

The design includes reverse-polarity protection on supply connections, output reverse-polarity protection, and output overcurrent/short-circuit protection.

What materials form the sensor housing and optics?

The enclosure is moulded from a polycarbonate/ABS blend while the optical elements use PMMA.
