Can anybody recommend the sensors which may be used with XR480 (XRxx)? Motion sensors, infrared sensors/detectors etc.? PMI has lots of XR480 installed in Russian and would like to use external sensors connected via LIB box to add some functionality totheir conveyor app. We had KT-70102-01 in the pricelist but looks like it's obsolete (together with XR itself) Any recommendations/experience? Thanks, Valery
