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.
