Small enough to fit any frame, the R311A is a magnetic contact that reports when a door, window, cabinet or hatch is opened or closed over LoRaWAN. Its reed switch and separate 43 mm magnet fix to the frame and leaf with no wiring, and two CR2450 coin cells power the 57 × 35 mm unit. Because it only transmits on a change of state, network traffic and battery drain stay low. Typical uses include monitoring fire doors and emergency exits, tracking access to stores, plant rooms and server cabinets, and confirming that fridge or freezer doors have been shut.
