Industrial sensing range
The Wenglor YK12NA7 is a photoelectric sensor with an adjustable detection range of 18...120 mm using a 655 nm red laser. It suits automation tasks that require precise presence detection on conveyors or small-part handling. The NPN antivalent output provides both normally-open and normally-closed signals from a single device. Buyers who need a longer sensing distance or a PNP output type will not be served by this model.
Thermal and electrical behaviour
Operating temperature spans -25...60 °C with a temperature drift below 5 %, and the sensor draws under 15 mA at 24 V DC from a 10...30 V DC supply. Switching frequency reaches 1300 Hz with a 385 µs response time, while built-in short-circuit, reverse-polarity and overload protection maintain stable operation. The laser is rated Class 2 per EN 60825-1 and offers a 100000 h service life at 25 °C.
Mounting and connectivity
A fully encapsulated plastic housing rated IP67 resists dust and water ingress in harsh environments. Connection is via an M8 × 1 4-pin plug, and the sensing distance is set with a potentiometer on the body. The package contains one sensor in a box. Installers who require a cable tail or a different connector format must source an alternative.

Questions about this item
How do I mount and wire the M8 4-pin connector, and which step is often missed?
Mount the plastic housing, connect the M8 4-pin plug to a 10...30 V DC supply, then adjust the potentiometer while the target is at the desired distance; the step often missed is fine-tuning the potentiometer after power-up.
What maintenance or replacement will the YK12NA7 need over time?
The laser light source is rated for 100000 h at 25 °C; after that the sensor may need replacement, and the lens should be cleaned periodically to maintain the 18...120 mm range.
What limit appears first during continuous high-speed operation?
The 1300 Hz switching frequency and 385 µs response time set the maximum detection speed; exceeding this rate causes missed signals before thermal or voltage limits are reached.
