Characteristics of cylinder magnetic switch

Magnetic switch cylinders are used to detect the position of cylinder stroke, without the need for machine control valves (or stroke switches) and their mounting brackets at both ends of the stroke, and without the need for collision blocks at the end of the piston rod, making them easy to use and compact in structure. Due to its high performance, long lifespan, low cost, and fast switching response time, it has been widely used.

Installation method of cylinder magnetic switch

1) Fix with steel strip

2) Fixed on the guide rail

3) Fixed on the pull rod

4) Direct installation

Installation position of cylinder magnetic switch magnetic switch

Magnetic switches can be installed at the end of the stroke or at any position in the middle of the stroke.

For situations where the magnetic switch needs to be installed in the middle of the stroke (such as stopping the piston at a certain position in the middle of the stroke), the installation position of the switch can be determined as follows. At the stop position of the piston, fix the piston and allow the magnetic switch to move left and right above the piston. Find the position where the switch starts to engage, and the middle position of the left and right engagement positions is the highest sensitivity position of the switch. The magnetic switch should be fixed at this highest sensitivity position.

When installing the switch at the end of the stroke, in order to install the switch at the highest sensitivity position, the distances A and B from the side end cover and rodless side end cover have been marked on the sample for different cylinders.

Magnetic switch

The magnetic switch has a large operating distance, interference, good sealing performance, stable magnetic force, and a hemispherical working characteristic. It is easy to install, has a long service life, and can work in high temperature, high temperature, and other harsh environments. They are widely used in steel rolling, coking, shipbuilding, mining, lifting, transportation and other fields as position control switches, or to replace the original slide contactor mechanical limit switches. They are an ideal component for achieving contactless transmission of control signals and replacing domestically produced products from abroad

Precautions for using cylinder magnetic switch

1) From consideration, the distance between the two magnetic switches should be 3mm greater than the maximum hysteresis distance.

2) Magnetic switches shall not be installed near strong magnetic field equipment (such as welding equipment, etc.).

3) When the magnetic switches of the two cylinders are used in parallel, the mutual interference caused by the movement of the magnetic body affects the detection. The distance between the two cylinder tubes should generally be greater than 40mm.

4) The speed v of the piston approaching the magnetic switch shall not exceed the maximum speed vmax that the magnetic switch can detect. The relationship between the maximum speed vmax and the minimum action range lmin of the magnetic switch, as well as the action time tc of the magnetic switch locking the load, is: vmax=lmin/tc

For example, if the action time of the solenoid valve connected to the magnetic switch is t=0.02s, and the minimum action range of the magnetic switch is 1min=10mm, then the maximum speed that the magnetic switch can detect is vmax=500mm/s. If the speed of the cylinder piston is less than 500mm/s, this magnetic switch can be used. If the piston movement speed is greater than 500mm/s and there is no suitable universal magnetic switch available, only functional magnetic switches can be selected.

5) The torque for tightening the screws when installing the switch should be appropriate. Excessive torque can damage the switch, while insufficient torque may cause the optimal installation position of the switch to deviate.

6) Regularly check whether the installation position of the magnetic switch is offset. When the piston stops at the set position, for the dual color switch, a green light indicates correctness, while a red light indicates deviation.

Precautions for using magnetic switches
(1) Voltage and current should be avoided from being outside the scope of use
(2) It is strictly prohibited to directly connect magnetic switches to the power supply. They must be used in series with the load (such as relays, etc.)
(3) Before selecting the connection for the magnetic switch, it is necessary to confirm the working power supply used. When using a DC power supply, the red wire of the magnetic switch should be connected to the positive side of the power supply.
(4) Please avoid using magnetic switch cylinders in environments with strong magnetic fields and high currents. If you want to use them, please add shielding devices
Choose cylinder accessories: Select cylinder accessories according to the requirements of action and connection
