Features
Standard Models
Many Variations in Standard Limit Switches
A Wide Range of Models
The WL Series provides a complete range of Limit Switches with a
long history of meeting user needs. Select environment-resistant
specifications, actuators for essentially any workpiece, operating
sensitivity matched to the workpiece, operation indicators to aid
operation and maintenance, and various wiring specifications.
Environment-resistant Models
Select from Six Types of Environment Resistance
The series includes Airtight Switches, Hermetic Switches, Heat-
resistant Switches, Low-temperature Switches, Corrosion-proof
switches, and Weather-proof Switches. Select the one required by the
onsite environment.
Spatter-prevention Models
Excellent Performance on Arc Welding Lines or Sites with
Spattering Cutting Powder
Ideal for Welding Sites
Stainless steel and resins that resist adhesion of spatters are used to
prevent troubles caused by zinc powder generated during welding.
Long-life Models
Mechanical Endurance of 30 Million Operations
Long-life Models for High-frequency Applications
Long life has been achieved by increasing the resistance to friction
and creating better sliding properties in the head mechanism. Greater
visibility is provided when setting with a fluorescent display for setting
the stroke.
Features Common to All Models
DPDB Operation
The double-pole, double-break structure ensures circuit braking.

Degree of Protection; IP67
O-rings, cover seals, and other measures provide a water-proof, drip-
proof structure (IP67).
Approved Standards to Aid Export Machines
Various WL/WLM switches are approved by UL, CSA, TÜV, EN/IEC,
and CCC making them ideal for export machines.
High-precision Models Available in All Switch Types;
Ideal for Position Control
High-precision models achieve a very small movement to operation
(approx. 5°) and a repeat accuracy that is twice that of basic models.
Operation Indicators for Easier Daily
Inspections*
Confirm operation with a neon lamp or LED for
easier startup confirmations and maintenance.
* Operation indicators are provided on Indicator-
equipped switches, Spatter-prevention Basic
Switches, and Long-life Basic Switches.

Models with Connectors to Reduce Wiring
Reduce wiring with one-touch connection. Models with direct-wired
and prewired connectors that make Switch replacement easier are
also available.
