Rectangular metal sensor housing with M12 connector and potentiometer adjustment

Sick

Sick WS/WE24-2B430 Compact Photoelectric Sensor NPN PNP

SKU CH-DFQX-6JN1Q

Compact through-beam photoelectric sensor with 0 to 60 m range, selectable NPN or PNP output, M12 connector and IP69K metal housing

  • Through-beam sensing reaches 60 m maximum range
  • Visible red LED simplifies alignment at 50 m distance
  • Selectable NPN or PNP output fits diverse controls
  • IP69K metal housing withstands harsh wash-down environments
  • 10–30 V DC supply with 500 µs response time

Compact Through-Beam Photoelectric Sensor

The Sick WS/WE24-2B430 is a rectangular through-beam photoelectric sensor designed for industrial detection tasks. It operates on 10 V DC to 30 V DC supply voltage and offers selectable NPN or PNP switching outputs. The metal zinc diecast housing provides IP69K enclosure rating for harsh environments. This sensor suits automation engineers needing reliable long-range presence detection.

Upgrade From Basic Proximity Sensors

This through-beam model replaces diffuse or retro-reflective sensors when detection range and reliability are critical. The jump is worth it for applications requiring up to 60 m maximum sensing range with visible red light. The 1 000 Hz switching frequency and 500 µs response time support high-speed production lines. Potentiometer adjustment allows fine-tuning for specific installation conditions.

60 m Range With 100 mA Output Capacity

The sensor comfortably handles long-distance detection up to 60 m with a 700 mm light spot at 50 m. It runs out when ambient temperatures exceed 60 °C during operation or 75 °C in storage. The 100 mA maximum output current limits direct drive of high-power loads. The M12 4-pin male connector requires compatible cabling for integration into control systems.

Questions about this item

What are the dimensions and mounting requirements for the WS/WE24-2B430 sensor?

The sensor measures 27 mm wide, 87.5 mm high and 65 mm deep. It has a rectangular metal housing made of zinc diecast and weighs 660 g.

How do I wire the M12 connector and select the correct output mode?

Connect the 4-pin M12 plug to a 10–30 V DC supply. Use the PNP/NPN selector and the light/dark selector on the housing to match your controller logic.

What maintenance does the sensor need and which parts can be replaced?

Clean the PMMA optics periodically to maintain the 60 m maximum range. The sender and receiver are separate units (part number 2021) so either can be replaced individually.
