Limitless™ WLS Series
Wireless Limit Switches
The Limitless™ product line combines the best of MICRO SWITCH™ heavy-duty limit switches with the latest commercial off-the-
shelf wireless technology. Wireless enabled limit switches can be used for position sensing and presence/absence detection for an
endless number of applications.
The Limitless™ Series is especially beneficial for remote monitoring applications where wiring or wire maintenance is not physically
possible or economically feasible. Combining this greater flexibility with proven harsh duty packaging can result in increased
efficiencies and improved safety for machines, equipment, OEMs, and operators.
What makes our wireless solutions better?
•
Enables control and/or notification from remote parts of
applications/machinery/manufacturing plants, where wiring is
too costly or not possible
Ability to reconfigure and network multiple switches and
interfaces with unique addresses that allows for adding,
subtracting, or relocating Limitless™ inputs easily
Limit, eyelet pull, and non-contact switches along with
single switch adapters allow for multiple wireless solutions to
accommodate almost any application
Reduced installation and maintenance costs eliminate the
need to wire switches, install conduit, apply strain relief,
mounting clips, connectors, junction boxes, etc.
Eliminates issues with wire connection integrity and cable
degradation on moving equipment

Features
and Benefits
WIRELESS DESIGN
Radio (license-free and global): WPAN 802.15.4, 2.4 GHz, point-to-point to deliver
reliable, flexible, and secure wireless transmission.
Offers control from
remote locations where wiring is too costly or not practical (up to 305 m [1000 ft]).
SEALED FOR HARSH ENVIRONMENTS
The Limitless™ Series features
industrial and NEMA ratings,
sealed zinc
die-cast and powder coated housings with direct or remote mounted antenna
options.
Range of 305 m [1000 ft]
REMOTE CONTROL AND MONITORING
When paired with the Limitless™ Monitor or Receiver, the WLS product line can
enable users to monitor and/or control equipment, access points, and presence/
absence detection in remote locations where wiring is too costly or impractical
to install. The WLS Series is designed to consume ultra-low power that helps to
prolong battery life and has
direct or remote mounted antenna options.
Consumes ultra-low power to prolong battery life
DESIGN OPTIONS
The WLS Series offers a broad range of actuator styles. Side rotary, top plunger,
eyelet pull, wobble stick, single switch adapter, and non-contact switch are all
available within the product line. Actuator heads on most models can be
rotated
in 90° increments
to allow for flexibility in applications. Multiple actuators can
also be applied to any side rotary WLS Limitless™ switch.
CONFIGURABILITY
All of the WLS Series Limitless™ switches can be easily paired with a WPMM
monitor or WDRR receiver providing multiple inputs that
easily allow for adding,
removing, or relocating Limitless™ switches.
This unique feature helps to
eliminate issues with wire connection integrity on moving equipment.
REDUCES COSTS
With no wires, conduit, strain relief, connectors, or junction boxes to install or
maintain, the WLS Series can
reduce maintenance costs and inventory
associated with maintaining and repairing equipment and facilities.
