HZCH-D1-A Permanent Magnet Safety Door Lock Device Permanent Magnet Safety Door Lock JNCH-D1B is a new product aimed at addressing safety hazards in on-site use of crane end beam boarding doors. It can replace door bolts and safety switches on end beam boarding doors, and has the advantages of long service life, strong seismic resistance, simple installation, no need to change the electrical control system, and prevention of safety hazards. Magnetic proximity switches are domestically produced products that replace imports. Due to the use of magnetic induction principle, they fundamentally solve the impact caused by any electric field interference. This series of switches has a long operating distance, strong performance, good sealing performance, stable and reliable magnetic force, and a hemispherical working characteristic. They have the characteristics of easy installation, long service life, and can work in high temperatures, high temperatures, and other harsh environments. They are widely used as position control switches in steel rolling, coking, shipbuilding, mining, lifting, transportation, and other fields, or replace the original slide contactor mechanical limit switches. They are an ideal component to replace imported domestic products and achieve contactless transmission of control signals& nbsp; Usage of permanent magnet magnetic field source; This usage is to fix a permanent magnet on the side wall of the lifting container, and install a magnetic switch on the designated position of the wellbore, wellhead, or mast, so that the switch end face sensor runs up and down the track space against the magnet. During the lifting process, when the magnet on the container reaches the magnetic switch position, the switch will act and send out signals such as deceleration and parking. Technical parameters:
