General-purpose Limit Switch
D4A-@N
The Limit Switch with Better Seal, Shock
Resistance, and Strength
• A double seal on the head, a complete gasket cover, and other features ensure a better seal (meets UL NEMA 3, 4, 4X, 6P, 12,
13).
• Block mounting method to reduce weight to 290 g.
• Block mounting method also reduces downtime for mainte- nance.
• Wide standard operating temperature range:
–40°C to 100°C (standard type).
• Models with fluoro-rubber available for greater resistance to chemicals.
• DPDT, double-break models available for complex operations.
