Industrial photoelectric sensor

The Wenglor OTDK502A0002 is a new PNP photoelectric sensor designed for industrial automation tasks. It detects objects up to 500 mm away using an infrared light source with a 5 ° opening angle. The sensor suits electricians and maintenance engineers who need reliable presence detection in harsh environments.

Supply voltage and switching limits

The unit operates from a 10...30 V DC supply and draws less than 30 mA at 24 V. Its PNP normally-open output switches up to 200 mA with a voltage drop below 2,5 V. Short-circuit, reverse-polarity and overload protection are built in, while the switching frequency reaches 500 Hz with a 1 ms response time.

IP67-rated plastic housing

The red plastic housing meets IP67 so it withstands dust and temporary immersion. Connection is via a 4-pin M12 × 1 connector, and a potentiometer allows range adjustment. Operating temperature spans -25...60 °C, and the MTTFd to EN ISO 13849-1 is 3706,54 a.

Questions about this item

Should I choose the 500 mm range version or a shorter-range model for my application?

This sensor detects objects up to 500 mm away using an infrared light source with a 5 ° opening angle. Select it when your target distance falls within that range; a shorter-range model would only be needed for closer, more precise detection.

What does the 500 Hz switching frequency mean when the sensor is installed on a production line?

At 500 Hz the sensor can complete a full detect-and-switch cycle every 2 ms, with a 1 ms response time, so it reliably tracks objects moving at typical conveyor speeds without missing pulses.

How does the M12 × 1, 4-pin connection limit the wiring options?

The 4-pin M12 connector carries the 10…30 V DC supply, the PNP normally-open output (200 mA max) and the error indicator signal. It fits standard M12 cables but cannot carry additional auxiliary contacts beyond those four pins.
