Industrial photoelectric sensor for precise

The Wenglor YN44PA3 is a red laser photoelectric sensor with an adjustable sensing range of 65...400 mm. It operates on 10...30 V DC and provides an NPN switching output with antivalent NO/NC function. The sensor suits automated lines that need accurate presence detection at up to 600 Hz switching frequency. Its IP67 housing withstands harsh industrial environments.

Verify supply voltage and wiring before ordering

Confirm your control system delivers 10...30 V DC and can accept an NPN output with a switching current up to 200 mA. The M12 4-pin connector requires a matching cable; pin assignment must match the antivalent NO/NC configuration. Ensure the operating temperature range of -25...60 °C covers the installation site. A potentiometer on the housing sets the exact switching distance.

Plastic housing with IP67 protection and M12

The sensor body is made of plastic rated IP67, resisting dust and temporary immersion. A red laser class 2 source at 655 nm produces a focused spot for small-part detection. The M12 × 1 4-pin plug enables quick disconnect and replacement without rewiring. Built-in short-circuit, reverse-polarity and overload protection reduce downtime. MTTFd is 1930,46 years per EN ISO 13849-1.

Questions about this item

What items are included in the box and is a mounting bracket or M12 cable supplied separately?

The box contains one Wenglor YN44PA3 photoelectric sensor. Mounting brackets and M12 4-pin connection cables are not included and must be purchased separately.

Should I choose this 65...400 mm adjustable range version or a different sensing distance for my application?

Choose this version when you need a red laser Class 2 sensor with an adjustable range of 65 to 400 mm, 600 Hz switching frequency and NPN/PNP antivalent output. Select a different model if your target distance falls outside this span.

How does the 600 Hz switching frequency and 833 µs response time perform on a fast conveyor line?

At 600 Hz switching frequency and 833 µs response time the sensor detects objects moving at high speed. The <1 % hysteresis and <2 % temperature drift keep detection stable from -25 °C to +60 °C.
