8mm round through-beam photoeyes offer high accuracy in minimal mounting space. They detect presence when an object obstructs light traveling from emitter to receiver. Using infrared light, these DC-powered metal sensors offer a sensing distance of 1m, and are available with integral 1m pigtail cable or quick-disconnect. Emitters and receivers are sold separately.
HEE/HER series through-beam sensors feature miniature 8 mm tubular stainless steel housings.
Small size and rugged IP67 rating make the HEE/HER series a good solution for sensing applications
with limited mounting space in harsh environments.
The M8 miniaturized HEE and HER series thru-beam sensors are available with NPN or PNP, and NO or NC outputs.
In the PNP models the load is connected between the output (black wire) and the negative (blue wire).
In the NPN models the load is connected between the output (black wire) and the positive (brown wire).
In the Normally Open models, the output is ON when the target is present (beam interrupted); in the Normally Closed models the output is ON when the target is absent (beam free).
All models feature a maximum switching frequency of 10 kHz that accommodates high speed counting or motion control applications.
