Actuator: Roller plunger.
Conduit openings: G1/2 (PF1/2).
1NC/1NO (Snap-action).
Robust safety limit switch with metal housing.
Slow-action and snap-action contact with,
certified direct opening operation certification.
Direct opening mechanism (NC contacts only) added to,
enable opening contacts when faults occur, such as fused contacts A22-DB-20A.
Safety of lever settings ensured using a mechanism that,
engages a gear between the operating position indicator plate and the lever A22-DB-20A
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 A22-DB-20A.
(TÜV: IEC IP67, UL: NEMA 3, 4, 4X, 6P, and 13) .
