SICK Fotoelektrický snímač, řada: W8 LED Pravoúhlý 8kolíkový konektor M4, výstup: PnP Retroreflexní IP67

SICK Series W8 Photoelectric Sensor, IP67, 0.25ms Response Time - WL8-P2231

This photoelectric sensor is a Compact retroreflective detector designed for industrial automation. It uses a visible red LED to identify objects at short to medium ranges and is housed in a small rectangular ABS enclosure rated to withstand dust and water ingress. The unit connects via a 4-pin M8 male connector and provides a PNP switching output suitable for control circuits operating up to 30V.

Features & Benefits

• 0.25ms response time enabling detection of fast-moving targets
  Up to 100mA output current supporting direct drive of small loads
  IP67 enclosure for operation in dusty or wet environments
  Selectable light/dark switching for flexible output logic
  Visible 650nm LED with Ø30mm spot for accurate alignment
  Operating range to 3M using standard reflector for Compact setups

**Applications**

• Suitable for high-speed object detection on conveyor lines
  Ideal for presence sensing with reflector-equipped stations
  Used for part counting in assembly and packaging systems
  Can be used for machine position feedback in automation cells
  Suitable for integration into control panels with M8 cabling

What supply voltage does it accept for stable operation?

It runs from 10V DC to 30V DC with a ripple tolerance of ±10% for typical industrial supplies.

How is switching behaviour selected on the device?

A rotary switch on the housing allows selection between light-on and dark-on modes for direct compatibility with different control logic.

What environmental temperatures can it withstand in service?

The sensor operates between −25°C to +55°C and can be stored between −40°C to +70°C for spare inventory.

What accessories are included with delivery?

The unit is supplied with a stainless steel mounting bracket and a reflector suited to retroreflective operation.

How is short-circuit and polarity protection handled?

The sensor incorporates reverse-polarity protection on supply connections and protection for inputs and outputs against common fault conditions.

Notes

For retro-reflective sensors a suitable reflector is required.
