1 DESCRIPTION
1.1 General
The WBX Series product line combines the best of MICRO
SWITCH™ heavy duty limit switches with the latest commer-
cial off-the-shelf wireless technology. Wireless-enabled limit
switches can now be used for position sensing and presence/
absence detection for a wide variety of applications. The WBX
Series is especially beneficial for remote monitoring applica-
tions where wiring or wire maintenance is not physically pos-
sible or economically feasible. Combining this greater flexibility
with proven harsh duty packaging can result in increased
efficiencies and improved safety for machine and equipment
OEMs and operators. This document will provide installation
instructions to properly install a WBX Series limit switch, or
simply the WBX.
1.2
Principle of Operation
The WBX will transmit the position of its actuator to a wireless
receiver. The wireless receiver will then indicate the actuator po-
sition of the WBX via a visual indicator, audible indicator and/or
electronic output. The WBX supports no electrical signal inputs
and is powered by a replaceable battery.
