Sick WF2-40B410 Фотоэлектрический датчик

SICK Series WF Photoelectric Sensor, 30V Maximum DC Voltage, 100mA Maximum Current - WF2-40B410

This photoelectric sensor is a fork-style optical device designed for precise object recognition in industrial control systems. It employs an infrared LED to detect small targets within a narrow beam and connects via a 4-pin M8 male connector for straightforward integration into automation and electrical assemblies. The unit is intended for panel mounting and operates across a wide ambient temperature range for use in manufacturing and processing environments.

Features & Benefits

• 0.1ms response time enables fast detection in high-speed lines
  10–30V DC supply supports common industrial power rails
  100mA maximum output current drives typical input circuits
  NPN/PNP selectable output suits diverse control systems
  IP65 aluminium housing resists dust and moisture ingress
  850nm infrared light source detects small targets down to 0.2mm

**Applications**

• Suitable for label presence verification on packaging lines
  Ideal for print registration and edge detection tasks
  Used for component detection on pick-and-place equipment
  Can be used for shaft or position sensing in assembly rigs

How is sensitivity adjusted during setup?

Sensitivity and light/dark switching are set using Plus and minus buttons with a visible function indicator to guide threshold changes.

What connector and wiring format does it use?

It uses a male M8 four-pin connector wired for either NPN or PNP switching and includes reverse-polarity and short-circuit protections.

How does it behave under fluctuating supply conditions?

Ripple tolerance is under 10% and the device is designed for operation within 10–30V DC with defined limit protections for network faults.

What are the environmental limits for storage and operation?

It operates between –20°C and +60°C and can be stored from –30°C to +80°C while maintaining function within those bounds.
