Industrial reflex sensor for 500 mm detection

The Wenglor OTDK502A0091 is a PNP reflex sensor designed for automated presence detection up to 500 mm. It operates on a 10...30 V DC supply and carries an IP67 rating for harsh environments. The unit suits machine builders and maintenance engineers who need reliable object sensing on conveyors or packaging lines.

Mounting console and 2 m cable included

A mounting console ships in the box so the sensor can be fixed immediately without separate brackets. The pre-wired 4-wire cable runs 2 m, removing the need to source and terminate a connector in the field. Both items reduce installation time compared with a bare sensor.

500 mm sensing range sets the application limit

The infrared beam detects objects out to 500 mm with a 5° opening angle and less than 15 % switching hysteresis. If the target must be sensed beyond this distance, the sensor will not reach it and a longer-range device is required.

Questions about this item

How long does the infrared light source last before it needs replacing?

The infrared emitter is rated for 100000 hours of service life at 25 °C ambient temperature.

At 500 Hz switching frequency, what is the first limitation during continuous operation?

The 1 ms response time sets the minimum cycle period, so the sensor cannot resolve events faster than one millisecond.

Does the plastic housing stay cool and quiet when running all day on 24 V DC?

Current draw stays below 30 mA at 24 V, so heat is minimal and the solid-state design produces no audible noise.
