How many amps can a magnetic reed switch handle?
Conversely, unlike electromechanical armature style relays, the Reed Relay can switch or carry currents as low as femptoAmperes (10-15 Amperes).
What is the contact rating of a magnetic switch?
Contact Rating or Maximum Switching Power, in Watts, is the maximum power a reed contact can switch. The contact rating for a reed switch application is the product of switching voltage and switching current that will pass through the reed switch.
What is the current rating of a switch?
The voltage and current ratings for the switch are 115 volt dc, 5 amperes.
What is the contact rating of a reed switch?
Contact rating or power rating is defined as the product of maximum switching voltage and maximum switching current. Contact rating is also a very important of a reed switch (or any other switch). For reliable performance of the switch, contact rating should never be exceeded.
Can a permanent magnet work with a reed switch?
The wider the distance between switch and magnet, the stronger the magnet will need to be to interact with the switch. Any permanent magnet will work with a reed switch but it is important to remember that different materials have different strengths and different sized magnets produce different sized magnetic fields.
What are the different types of reed switches?
Reed switches come in two basic types: Normally Open and Normally Closed. Normally Open Reed Switches. In a Normally Open reed switch design, the switch defaults to an open position, breaking the circuit. When an outside magnet approaches, it polarizes the two contacts, allowing them to attract each other and snap together.
What should be the Gauss value of a reed switch?
If your switch only states the ampere-turns and not Gauss value it is possible to use the conversion of 1 Gauss = 1 ampere-turn but this is not an exact science and should only be used as a guide. The lower the AT rating or Gauss, the lower the magnetic field strength required to actuate the reed switch.
