Contact Resistance.
The contact resistance is the electrical contact formed by the conductor resistance and the surface film electricity divided into two sections by a conductor, which has a much larger resistance than the original conductor. This resistance is called contact resistance. The contact resistance of the relay refers to the resistance between the contacts.
Operate-Voltage (Set-Voltage)/ Release-Voltage (Reset-Voltage).
Operating voltage (OV): The minimum voltage required by the coil when all the contacts of the relay reach the working state from the reset state.
Reset voltage (RV): The minimum voltage required by the coil when all the contacts of the relay reach the reset state from the working state.
Action (set) time / release (reset) time Operate-Time (Set-Time)/ Release-Time (Reset-Time).
Action time (OT): the time required from the start of the coil energization to when all the contacts reach the working state.
Reset time (RT): The time required from the moment when the coil is de-energized to when all the contacts are fixed to the reset state.
Insulation-Resistance/Dielectric-Strength
Insulation resistance: The resistance value that appears when measured with a specified DC voltage between conductive parts that are insulated from each other
Withstand voltage: also known as dielectric strength, refers to the maximum voltage gradient that a dielectric material can withstand without failure
Rated Voltage/Rated Current
The rated specification value when the relay is designed. When the relay is used under normal conditions, the voltage (current) applied to the coil is based on this
When using a relay, due to the voltage of the actual circuit or the use environment may fluctuate, the voltage applied to the two ends of the relay coil may also fluctuate. In order not to affect the normal use of the relay, it is stipulated that the relay can be applied during use. The voltage range. (Each product has an allowable voltage range, please refer to the specification when using it. If there is no special instructions, the allowable range is the rated value +/-5%)
Contact form
Normally open contact: a contact that is open in the normal state.
Normally closed contact: A contact that is closed in the normal state.
Conversion contact: one side is normally closed, the other side is normally open
MBB contact: In the conversion contact, the normally closed side has not been disconnected, but the normally open side has been turned on.
