Industrial Reflex Sensor
The Wenglor HK12PA7 is a PNP reflex sensor designed for industrial automation and machine-monitoring tasks. It detects objects at an adjustable range of 18...120 mm using a red-light source. The sensor operates on a 10...30 V DC supply and draws less than 25 mA at 24 V. Its IP67-rated plastic housing is fully encapsulated for harsh environments.
Upgrade From Basic Switches
This sensor replaces simple mechanical limit switches or fixed-range photoelectric sensors where adjustable detection distance and faster response are needed. The jump is worth it when an application requires a switching frequency of 1300 Hz and a response time of 385 µs. Potentiometer adjustment allows fine-tuning without replacing the unit.
Detection Capacity And Limits
The unit comfortably handles detection tasks within the 18...120 mm window with a switching hysteresis below 10 % and temperature drift under 5 %. It runs out when ambient light exceeds 10000 Lux or when the required switching current surpasses 100 mA. The service life is rated at 100000 hours at +25 °C.

Questions about this item
What size mounting hole or thread does the M8×1 4-pin connector on the HK12PA7 require?
The sensor uses an M8×1 4-pin connector; the panel cut-out must match an M8×1 thread to secure the plug and maintain the IP67 seal.
Which potentiometer adjustment sets the switching distance, and what is the common mistake during setup?
Turn the potentiometer while the target is at the desired distance within the 18...120 mm range; the frequent error is adjusting with no target present, which leaves the threshold undefined.
After how many operating hours should the red light source be checked, and what indicates it needs replacement?
The emitter is rated for 100000 h at +25 °C; a noticeable drop in switching reliability or increased hysteresis beyond < 10 % suggests the light source is ageing.
