Contact configuration(door open/closed detection switch,
and lock monitor switch contacts): 3NC+3NC.
Conduit opening: G1/2.
Holding Force of 3,000 N.
Two safety circuits and two monitor contacts provide an,
array of monitoring patterns D4F-420-3R PDF datasheet.
Standard gold-clad contacts enable use with ordinary loads,
and microloads D4F-420-3R
Models with trapped keys prevent workers from being locked,
in hazardous work areas.
Models with rear release buttons allow people to unlock the,
Switch and escape if they are locked into hazardous areas.
IP67 degree of protection. Receptacle box: G 1/2 Conduit D4F-420-3R PDF datasheet.

Approved standards: UL, CSA.
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).
Wide standard operating temperature range:
-40°C to +100°C (standard type).
Models with fluoro-rubber available for greater resistance to chemicals D4F-420-3R PDF datasheet.
Block mounting method also reduces downtime for maintenance.
DPDT, double-break models available for complex operations.
Approved by UL, CSA, and CCC (Chinese standard).
