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
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 benecial for remote monitoring applications where wiring or wire maintenance is not physically
possible or economically feasible. Combining this greater exibility with proven harsh duty packaging can result in increased
efciencies and improved safety for machines, equipment, OEMs, and operators.

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.
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.
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.
Consumes ultra-low power to prolong battery life

Potential Applications
Limitless™ WLS Series • Non-Contact Limit Switch
Honeywell’s Limitless™ Wireless Non-Contact Switch provides non-contact presence/absence detection of a variety of different magnet
styles and magnetic actuators installed on the end-users’ product, machine, equipment, etc. The Limitless™ WLS Non-Contact Switch’s
design features an industrial grade reed switch. Customers can choose how the reed switch is oriented within the switch’s plastic head,
i.e., either top- or side-sensing. Combining this greater flexibility with proven harsh-duty packaging can result in increased efficiencies and
improved safety for industrial machines, equipment, OEMs, and operators.

Potential Applications
Limitless™ WLS Series • Single Switch Adapter
Honeywell’s Limitless™ Single Switch Adapter can convert almost any electromechanical switch with low-energy contacts (i.e., gold) into a
wireless switch. A user-supplied electromechanical switch is simply wired to the WLS Series Single Switch Adapter via the internal or exter-
nal connections to then become a wireless-enabled switch for use with the Limitless™ WPMM or WDRR Series of monitors/receivers. The
Limitless™ Single Switch Adapter can be used in a variety of industrial wireless limit switch applications such as reed, contact, pressure,
door actuator, etc. Honeywell offers numerous styles of low-energy contact switches. From sealed heavy-duty limits to small basics and
subminiature switches, Honeywell can provide a low-energy solution that is compatible with the Limitless™ Single Switch Adapter. Contact
your Honeywell representative or distributor for details.
