Its wireless range extends up to approximately 500 ft in typical conditions. The transmitter is weather-resistant (IP66) and incorporates RF anti-scan protection to guard against unauthorized capture of signals. It uses a CR2032 lithium coin-cell battery. This pendant is ideal for gate controls, access control systems, garage doors, lighting automation and other wireless release applications where reliability, security and compact design matter.
