H contact form: the contact group that is closed in the operating state of the relay and disconnected in the release state; D contact form: the contact group in which the relay is open in the action state and closed in the release state; Z-contact form: a combination of tw..
IEC61810-Basic Electromechanical Relays; GBT 21711.1 - Basic electromechanical relays – Part 1: General provisions and safety requirements; UL508 - Industrial Control Devices. IEC 60335-x standard: Safety Code for Household and Similar Electrical Appliances
Manual soldering: manually use an electric soldering iron for soldering, soldering iron tip temperature: 340°C-360°C, soldering time: within 3s.
Special requirements for the main materials of various types of relays
Working principle: the coil generates electromagnetic force through the current to attract the armature, the armature drives the moving contact to close with the normally open static contact, when the coil removes the current to make the electromagnetic force disappear, the movi..
The structure of electromagnetic relay mainly includes: Magnetic circuit system: core, yoke, armature, coil and other parts; Contact system: static reed, moving reed, contact, base and other parts; Return mechanism: Composed of restored reed or tension spring.
Please note that there is a risk of electric shock if you touch it with your hands while the relay is working properly.
Relays play a vital role in countless consumer, commercial, and industrial applications and systems. They are often inadvertently used in everyday systems.
