Permanent magnet safety door lock JNCH-D1A | With a rated current of 6A, it adopts passive magnetic induction and does not require external power supply. Only the red and blue leads can be connected to the translation control circuit. In order to ensure the normal operation of the internal status indicator light of this device, please choose to use it in the correct circuit. Product Description: Permanent Magnet Safety Door Lock JNCH-D1A | 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 the crane end beam boarding door. It can replace the door bolts and safety switches on the end beam boarding door, 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 door is close to this product, the strong magnetic device tightly attaches the boarding door to the device, and at the same time, outputs a signal to the electrical control system, playing a synchronous role in locking the door and signal output, so as to prevent safety hazards. When the staff pass through the end beam boarding gate, the operation is simpler and the passage is more convenient. Technical parameters: 1. Rated current: 6A2, rated circuit voltage: 110-380V3, ambient temperature: -20 ℃ -+65 ℃ 4. Relative humidity:< 95% (+25 ℃/5), suitable for environments with severe dust, including conductive powder. 6. Suitable for places with moderate or lower vibration or impact. 7. Housing protection level: IP67. Usage: Fix the safety door device on the angle steel with M8 screws and wire it according to the requirements. Voltage naming method: Permanent magnet safety door lock JNCH-D1A (110-380V/Permanent magnet safety door lock JNCH-D1B (12-36V/When the magnet passes through the mining proximity switch from one direction, the output contact is closed and held. When passing through the proximity switch again from another direction, the output contact is disconnected and held. g/Sealing products are strictly prohibited from striking during operation and modification is strictly prohibited to affect explosion-proof performance. The surface magnetic field of the matching magnetic steel must be ≥ 1300GS. JNCH-D1B permanent magnet safety door lock
