Attention Hubbell-Wiegmann Enclosure Customers: Please note that any lead-time enclosures purchased Monday, Oct 15th or Tuesday, Oct 16th will require 2 extra lead-time days in addition to the published lead-time shown in our store. Backordered items will also require an extra 2 days. This is due to production stoppage during their inventory process. We apologize for any issues this may cause. Stock items will ship normally.
Rectangular photoeyes with round threaded lens detect presence several ways: diffuse with background suppression (light reflects from the target object back to the sensor), retroreflective (object interrupts light rebounding off a fixed reflector), or through-beam (object obstructs light traveling from an emitter to a receiver). Models are available in a variety of sensing distances.
