JNCA-D1A Permanent Magnet Safety Door Lock Specification Parameters JNCA-D1A Permanent Magnet Safety Door Device End Beam Boarding Gate Rated Current 6A, also known as Permanent Magnet Safety Door Device, is a new product for crane permanent magnet anti-collision safety door device. It is designed to address safety hazards in on-site use of crane end beam boarding gates and can replace door bolts and safety switches on end beam boarding gates. It has a long service life, strong seismic resistance, simple installation, no need to change the electrical control system, and prevents safety hazards. This product is equipped with a strong magnetic device. When the end beam boarding gate is close to this product, the strong magnetic device tightly attaches the boarding gate to the device, while outputting signals to the electrical control system. The synchronization between locking the door and signal output makes it easier for staff to operate and pass through the end beam boarding door.
