Sick WTB8-P2231 Фотоэлектрический датчик

SICK Series W8 Photoelectric Sensor, Background Suppression Detection Type, IP67 - WTB8-P2231

This photoelectric sensor detects objects using background suppression and is designed for panel mounting in industrial automation environments. It uses an LED light source and a PNP switching output to provide fast object sensing for production, handling and inspection tasks while operating across typical factory temperature ranges.

Features & Benefits

• 0.5ms response time supports high-speed detection requirements
  IP67 protection permits use in dusty and washdown conditions
  PNP output enables easy integration with PLC inputs
  30V DC and 30mA limits simplify power budgeting
  Plastic ABS housing reduces weight and resists corrosion
  4-pin M8 Terminal eases secure field wiring connections

**Applications**

• Suitable for high-speed conveyor object detection
  Ideal for presence sensing in pick-and-place stations
  Used for part orientation checks in assembly lines
  Can be used for material handling verification in packaging
  Suitable for integration into control panels for automation systems

What temperature range can it operate within for continuous use?

It functions reliably between -25°C and 55°C, allowing deployment in chilled storage interfaces and warmed production zones.

Which standards does it meet for photobiological safety and market approvals?

It complies with DIN EN 62471 and carries EU, UK and ACMA approvals, and meets RoHS restrictions for hazardous substances.

What mounting and connection considerations should be planned?

The unit is intended for panel mounting and connects via a 4-pin M8 terminal, so panel cut-outs and compatible cable assemblies should be specified in advance.

Is it suitable for hazardous-area certification needs?

It is supplied without hazardous-area certification and should not be used where such approval is required.

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.
