SICK Series W9 Photoelectric Sensor, Pin Point LED Light Source, IP69K - WL9-3P2230

This photoelectric sensor is a Compact retroreflective detector designed for industrial automation tasks where reliable object detection is required. It uses a focused red light source and a reflector to sense targets at medium range while operating across a wide supply voltage window, making it suitable for integration into control systems in production and process environments.

Features & Benefits

• PinPoint LED emitter for small light spot and precise detection
  PNP complementary output enabling easy PLC integration
  Fast response time 500μs for high-speed switching
  Ingress protection IP69K, IP67, IP66 for washdown and harsh conditions
  Low current consumption 30mA reducing system power draw

**Applications**

• Suitable for conveyor object presence detection with a reflector
  Ideal for pick-and-place verification in assembly lines
  Used for access control sensing in food processing washdowns
  Can be used for detecting reflective labels on packaging lines
  Used with PLCs requiring a 4-pin M8 connector Interface

What electrical connection does it use and how many pins are present?

It connects via a male M8 4‑pin connector providing supply and PNP switching output signals.

How does the sensor behave with thermal variations in industrial settings?

It functions across −40°C to +60°C ambient with storage to +75°C, and allows reduced maximum load current above +50°C.

Which optical targets and ranges can be expected with a reflector?

With appropriate reflectors the device senses from 0m up to 2.5m typically and up to 4m maximum depending on reflector type.

How is electrical robustness handled for industrial installation?

The unit includes reverse-polarity protection and interference suppression circuitry alongside short-circuit network limits for safe integration.

What indicators assist in commissioning and status monitoring?

It provides separate LEDs to indicate power presence and received light beam status for straightforward alignment and diagnostics.
