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
مقدمة المنتج
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.
الخصائص الرئيسية
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.
مخاوف المنتج للعملاء
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.
