The Limitless Series of switches is based on 802.15.4 point-to-point communications and can be configured to allow potentially up to sixteen devices to communicate with one receiver module. The products are based on Honeywell's proven harsh-duty and medium-duty limit switches. They have the same mechanical life, temperature ratings, and sealing as standard switches, but they're wireless. Wireless functionality is implemented through an 802.15.4 open protocol RF board operating in the 2.4 GHz globally license-free frequency band. The wireless signal is received by either a panel-mount receiver, or an industrial DIN-rail module, that converts it to an output. Outputs can be LEDs, buzzers, or electrical signals. The capability also exists to provide CAN, ProfiBus, and standard Ethernet communications
