Z Pass Box Bloqueio Magnético

A compact fail-safe electromagnetic lock set for retaining an interlocked pass box door during the transfer sequence.

Fail-Safe Electromagnetic Holding
Matched Armature Plate
Compact Chamber Mounting
Two-Core Electrical Lead

Introdução do produto

The pass box magnetic lock retains one transfer-chamber door while the opposite door is in use. The set combines a compact aluminum-bodied electromagnet, a matched armature plate, a stainless L-bracket and a short two-core lead for connection to the interlock controller. When correctly aligned, the floating armature seats evenly against the magnetic face and releases when power is removed. Replacement selection must match supply voltage, controller output, available mounting space, door geometry, holding requirement and the fail-safe sequence of the existing pass box.

Características-chave

The matched electromagnet and armature provide repeatable holding across frequent transfer cycles.

A compact rectangular body fits restricted header or side-jamb service spaces.

The stainless L-bracket provides slotted adjustment for face-to-face alignment.

A dedicated red-and-black lead simplifies polarity identification during replacement.

Preocupações do produto do cliente

Reliable magnetic holding depends on electrical compatibility and full, parallel contact between the magnet face and armature.

A tilted armature contacts only one edge and substantially reduces holding force.The mounting bracket and armature position are adjusted to provide flat, parallel face contact when the door closes.

The wrong coil voltage can cause weak holding or premature coil failure.The lock voltage and current demand are matched to the pass box controller output before connection.

A rigidly mounted armature may not accommodate small door-alignment changes.The armature is installed with the intended limited compliance so it can seat evenly on the magnetic face.

Residual magnetism or incorrect control logic can delay door release.A compatible low-residual lock and fail-safe control sequence provide prompt release when the output is de-energized.
