To improve heat resistance, silicone rubber is used for rubber parts and for the built-in switch. The operating temperature range is +5°C to 120°C.

To improve low temperature resistance, silicone rubber is used. The operating temperature range is –40°C to 40°C.

Diecast parts such as the switch box are made of corrosion-proof aluminum. Rubbersealing parts are made of fluorine rubber and exposed nuts and screws are made of stainless steel. These all aid in resisting oil, chemicals and adverse weather conditions.

--- Rotary shafts are made of unquenched (i.e., untreated) stainless steel to improve corrosion resistance. Exposed nuts and screws are made of stainless steel and rubber sealing parts of silicone rubber. These factors all combine to create a product which is resistant to temperature changes and adverse weather conditions.

Lit when operating and not lit when not operating. WL@-LE: 100 VAC/VDC min. WL@-LD: 115 VAC/VDC min. (Refer to page 71 for detailed ratings.)

■ List of Models

General-purpose Models

These Limit Switches are two-circuit double-break switches housed in rugged diecast, thus making it an oil-tight, waterproof and dustproof construction (complies with IP67).

In addition to the standard models, microload models are also available. A wide range of actuators with a range of functions are available; rotating lever, plunger, flexible rod etc. The rubber material in the standard models is designed to be resistant to water and most oils.

Note: For the model number of Heads without lever, simply remove the numbers after WL-@H. For example, WL-1H1100 becomes WL-1H. WLH2

and WLH12 however, become WL-2H-1, and WLGCA2 becomes WL-1H-1. Other Head models are available, but must be ordered separately.
