Vishay / Sfernice WLMO Wireless Position Data Transfer Modules
Vishay / Sfernice WLMO Wireless Position Data Transfer Modules power, remotely acquire, and wirelessly transmit data from up to two analog position sensors to users' receivers/gateways. The data is further processed within the host system for enhanced operational visibility and informed decision-making. The WLMO supports potentiometric and contactless sensor technologies. These Vishay / Sfernice position data transfer modules operate worldwide in the 2.4GHz ISM band, using a proprietary protocol layer over LoRa modulation. The modules use a private LoRa network with no license required, while maintaining long-range and low-power-consumption capabilities. A sealed mechanical switch provides secure activation and pairing during commissioning. The user can tune the WLMO modules by sending parameterization queries wirelessly.
