What is the difference between magnetic lock and electric lock?

The principle of the magnetic lock is the same as that of the electromagnet. It is the principle of using electro-magnetic and then the opposite pole attracting. When the current passes through the silicon steel plate, the electromagnetic lock will generate a strong suction force to hold the adsorbed iron plate tightly to reach the door. effect. As long as the small current electromagnetic lock will generate great magnetic force, the access control system that controls the electromagnetic lock power supply will identify the personnel and then turn off the power, and the electromagnetic lock will lose its suction to open the door. Because the electromagnetic lock has no complicated mechanical structure and the structure of the bolt, it is suitable for the access control of the escape door or the fire door. Its interior is protected by epoxy resin. At present, the suction strength of the electromagnetic lock is represented by LB (pounds), and the test method is static pressurization. The so-called static pressure is the electromagnetic lock gradually increases the tension on the adsorption iron plate after the energization, when the electromagnetic lock's suction exceeds the moment when the absorption of iron plate, the tensile force data is the value of the electromagnetic lock pull. In addition, the force of the electromagnetic lock and the adsorption iron plate must be face-to-face and linear pressure, so that the suction force of the electromagnetic lock is the largest. Adsorption iron plates may be magnetized for a short period of time due to the magnetic induction of the electromagnet for a long time.

The electric plug lock is an electronic control lock, and the function of locking or opening the door is achieved through the opening and retraction of the “tongue” through the on-off of the current. Usually the electrical latch consists of two main parts: the lock body and the keyhole. The key component in the lock body is the "lock tongue", and the "keyhole" cooperation can realize the "closed door" and "open door" two states. That is, the lock tongue is inserted into the lock hole to close the door, and the lock tongue leaves the lock hole to open the door. It is because of the retractable function of the tongue that the name of the “electric plug” is awarded. It is also because of this feature that electrical plug locks are often used for various swing doors (two-way opening). At the same time, the characteristics of its “hidden” installation are more suitable for places where the confidentiality of the lock body is relatively high.

The design of the magnetic lock is the same as that of the electromagnet. When the electric current passes through the silicon steel plate, the electromagnetic lock will generate a strong suction force to firmly attract the adsorption iron plate to achieve the effect of locking the door. As long as the small current electromagnetic lock will generate great magnetic force, the access control system that controls the electromagnetic lock power supply will identify the personnel and then turn off the power, and the electromagnetic lock will lose its suction to open the door.

The output of the signal output between the card and the magnetic lock and the electric lock. Usually the signal transmission way between them is through, RS422, RS485, RS232 several kinds of commonly used data transmission ways, among them RS422 is the duplex data transmission way. Transferred outside. Transmission data is generally odd. 3-wire and 5-wire signal lines are used for wiring. In the door sill system, it is connected with magnetic lock or electric lock signal sensing.

Clutch Release Bearing

The clutch release Bearing is a bearing fixed on the shaft going into the gearbox, which is movable along it. It is operated when you push clutch pedal to floor and cause the clutch mechanism to operate thus stopping driving force from engine being carried through to gears.

Whenever we change a clutch, we should change entire assy, including release bearing at same time. Best have a specialist do this for you. That is what we do. Various models of clutch release bearings, more than hundred different types, are applying in American, European, Japanese and other cars.

The clutch slave cylinder is a component found on vehicles equipped with manual transmissions. It works together with the clutch master cylinder to disengage the clutch when the pedal is pressed so that the transmission can be safely shifted. now clutch slave cylinder bearing works.
