Wide Range of Two-circuit Switches; Select One for the Operating Environment/Application
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.
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.
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.
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
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.
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.
