Safety Limit Switch
D4B-
@N
Snap-action contact with certified direct
opening operation certification
.
Maintenance, seal, and resistance to
shock increased and direct opening
mechanism added.
Three-conduit switches and 2NC
switches are also available.
Direct opening mechanism (NC contacts only) added to
enable opening contacts when faults occur, such as fused
contacts.
Safety of lever settings ensured using a mechanism that
engages a gear between the operating position indicator plate
and the lever.
Equipped with a mechanism that indicates the applicable
operating zone, as well as push-button switching to control left
and right motion.
Head seal structure strengthened to improve seal properties
(TV: IEC IP67, UL: NEMA 3, 4, 4X, 6P, and 13).
Wide standard operating temperature range:
–40 to 80
°C (standard type).
Models with gold-plated contacts added to the series to
enable handling microloads.
Certified standards: UL, CSA, EN (TV), and CCC.
