We will be performing maintenance on several web store related systems on Saturday, December 15th, begining at 6:00 AM EST and ending by 6:00 PM EST. There may be brief outages and some store features may be unavailable periodically during this time. We regret any inconvenience this may cause.
5mm round stainless steel photoelectric sensors detect presence several ways: diffuse (light reflects from the target object back to the sensor), or through-beam (object obstructs light traveling from an emitter to a receiver). Using infrared light, available models offer a selection of sensing distances and connection styles.
