Reed switch, also known as Magnetic reed switch or Motion sensor switch, is a switching element controlled by magnetic field signals. It is to lead the wire of the reed switch encapsulated in the casing, and the plastic casing with the magnet is fixed at the other end.
When the magnet is close to the switch with the wire, a switch signal is sent to turn on the wire. Generally, the distance to connect the signal is 10mm.
When there is no magnetism, the wire is disconnected and can be used to detect the state of electrical circuits or mechanical movement.
◆ Switch type: Normally open
◆ Operating Voltage: 5~240V DC/AC
◆ Ambient temperature: -10~70℃
◆ Switching current: 100~200mA max.
◆ Contact rating: 6~10W max.
◆ Easy to install
◆ Complete variety, can be applied to various of cylinders
◆ Very Sensitive
◆ Long work life
◆ The length and color of the lead wires can be customized according to your requirements
◆ The voltage and current should not exceed the usage range.
◆ It is strictly forbidden to connect the magnetic switch directly with the power supply, and it must be used in series with the load (such as relay, etc.).
◆ Before selecting and connecting the magnetic switch, 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 pole of the power supply.
◆ Please avoid using the magnetic switch cylinder in an environment with strong magnetic field and high current. If you want to use it, please add a shielding device.
◆ Select the cylinder accessories: according to the requirements of action and connection, select the cylinder accessories.
◆ For round cylinders without mounting grooves, you need to purchase mounting clamps for the reed switches.
The magnetic switch is mainly used to control and detect the movement position of the piston in the cylinder, so as to control the running position of the equipment or machinery. It can also be used to control the actions of industrial machinery, such as conveyor belts, rotating discs, lift tables, etc.
◆ According to the installation method on the cylinder, it can be divided into: CS1-M series, CS1-S series, CS1-U series, CS1-F series, etc.
◆ According to the number of wires, it can be divided into: two-wire type and three-wire type. And the three-wire type is classified into two types: NPN type and PNP type.
A reed switch is a magnetic sensing switch typically composed of two ferromagnetic metal reeds sealed within a glass tube.
When an external magnetic field is applied, the reeds are drawn together by magnetic force, closing the circuit.
When the magnetic field is removed, the reeds return to their original state, opening the circuit.
This type of switch is commonly used for position detection, counting, limit switches, and other applications.
First, check the reed switch for any physical damage, such as broken glass or damaged internal reeds.
Use a strong magnet near the reed switch to observe its response. The switch should close the circuit when the magnet is nearby and open the circuit when the magnet is removed.
Set a multimeter to continuity mode and test the two terminals of the reed switch.
The multimeter should show an "open" state when there is no magnetic field, and a "closed" state when the magnetic field is present.
You can also test the reed switch’s ability to handle current by connecting it to an appropriate power source and load, ensuring it performs reliably under typical operating conditions.
Avoid Magnetic Interference: Since the reed switch operates by magnetic induction, it’s important to avoid strong or erratic magnetic fields that might interfere with its operation.
Proper placement during installation can help minimize this issue.
Protect from Moisture and Dust: Although reed switches are sealed in glass tubes, they should still be kept in dry and clean environments to avoid degradation of performance over time.
Ensure the surrounding environment is free of excessive moisture or contaminants.
Regular Inspection: Periodically check the reed switch for proper operation, especially when used in high-vibration or high-temperature environments.
Ensure the switch responds to magnetic field changes and isn’t stuck or failing.
Avoid Overload: Never exceed the reed switch’s rated voltage or current. Overloading can cause damage to the internal structure, affecting its reliability and lifespan.
Replace Damaged Reed Switch: If the reed switch fails to respond to magnetic fields, is physically damaged, or shows signs of malfunction,
replace it promptly to ensure the system continues to operate correctly.
