Long-life Two-circuit Limit Switch

WLM

New Long-life Limit Switches Added to the
Wide Variety of WL Models

• Improved resistance to abrasion and smoother movement in the

head section means that a mechanical life of 30,000,000 oper-
ations minimum is now a reality.

• Wiring and replacement for maintenance purposes are easy

done.

• Fluorescent indicators improve visibility when setting stroke

zones.
