Wireless limit switches feature an internal electrodynamic energy generator. No battery required. Displacement of the actuator generates power to send a unique, coded telegram to one or more compatible, easily-programmed Receivers. If limit switch does receive the confirmation signal within 15ms, it transmits a second telegram. Receiver accepts up to 10 discrete telegrams per channel.
