Steute Industrial Controls offers a comprehensive line of wireless, batteryless limit switches that feature an internal electrodynamic energy generator. Displacement of the actuator generates power to send a uniquely coded signal to one or more compatible, easily programmed receivers. If the limit switch does not receive the confirmation signal within 15 ms, it transmits a second signal. The receiver accepts up to 10 discrete signals per channel. Available for operation at 915 MHz (U.S./Canada/Australia) or 868 MHz (Europe), the limit switches have a maximum transmission range of 40 m (130 ft) indoors, 450 m (1475 ft) outdoors, and a mechanical life expectancy of >1 million actuations. Operating temperature range is -20 to +65°C (-4 to +149°F). Options include a variety of actuator styles (e.g., roller plunger, roller lever, rocker lever, spring rod) and transmission range extenders.
