SICK Through Beam Photoelectric Sensor, Block Sensor

SICK W150 Series Photoelectric Sensor, IP67, 30V Maximum DC Voltage - WS/WE150-P430

This photoelectric sensor detects objects using a through-beam arrangement and is intended for industrial automation and process-control environments. It operates with a polarised red light emitter and connects via a four-pin M8 interface, offering straightforward integration into sensing and control systems where reliable object detection is required.

Features & Benefits

• PNP output supports direct interfacing with PLC inputs
  500μs response time enables fast detection cycles
  IP67 ingress protection allows operation in wet conditions
  Operates between -25 to 55°C for wide ambient use
  Maximum 30V DC supply suits common control voltages
  Plastic housing with through-hole mount simplifies installation

**Applications**

• Suitable for conveyor object presence monitoring in factories
  Ideal for machine guarding where emitter and receiver are separate
  Used for part counting in automated assembly lines
  Can be used for alignment checks in mechanical systems
  Suitable for inventory sorting systems in distribution centres

What connector type is provided for wiring?

A four-pin M8 connector is supplied for electrical connection, enabling standardised cabling and quick replacement.

How does the sensor perform in electrically sensitive installations?

It draws up to 100mA, limiting load on power circuits, and is compatible with 30V DC control supplies to match common industrial logic levels.

What approvals support use in regulated installations?

It carries recognised UL file references covering product conformity assessments relevant to electrical safety listings.

How is the sensor mounted to maintain alignment?

The unit is designed for through-hole mounting which provides fixed positioning for emitter or receiver modules within a system.

What optical characteristics aid detection of small targets?

The polarised red light beam reduces false signals from reflective surfaces, improving discrimination of target objects.
