The temperature range of environment
The temperature range of environment refers to the range (from the highest environmental temperature to the lowest environmental temperature) in which the relay is allowed to operate.
The temperature range of storing
The temperature range of storing refers to the range (from the highest environmental temperature to the lowest environmental temperature) in which the relay is allowed to be stored.
Vibration (sinusoidal motion)
Vibration refers to a sinusoidal motion of repeat cycle, its acceleration value is the function of displacement and frequency. Under the influence of the frequency range and acceleration stipulated by the product standard, the open time of any pair of the relay's closed contacts is less than 10μS or 100 μS and the closed time of any pair of open contacts is less than 10μS.
Shock strength
Shock strength refers to the capability with which the product can keep its normal operation after the product is influenced by a force impulse of a given-size, waveform, sustaining time and continuous one-way. Under the shock influence of the acceleration and shock times stipulated by the product standard, in the relay, there are no loosened parts and mechanical damage, and the electrical parameters are in accord with requirements.
Shock stability
Shock stability refers to the capability with which a product keeps normal operation under the influence of a force impulse of a given size, waveform, sustaining time and one-way. Under the shock influence of the acceleration and shock times stipulated by the product standard, the jittering (i.e. the opening of closed contacts and the closing of open contacts) time of any pair of contacts should be in accord with the stipulation. The longest allowable value of the jittering time of contacts is: 10 μS, 100μS.
Constant acceleration
Constant acceleration refers to the acceleration with which the product rotates around a certain axis. Under the influence of the constant acceleration stipulated by the product standard, the pick-up and release voltages of the relay should correspond to the stipulation of the product standard.
Insulation resistance
The relay's insulation resistance refers to the presented resistance value of the insulating parts between disconnected conductive parts when a certain DC voltage is applied to the insulating parts.
Dielectric withstanding voltage
The relay's dielectric withstanding voltage refers to the capability with which the insulating parts between disconnected conductive parts, are free of breakdown and excessive leakage current when the insulating parts are influenced by the stipulated voltage.
Contact resistance
It is the resistance of a pair of contacting pieces under stipulated conditions.
Actuating voltage
The lowest value of the winding voltage (or current) is needed by all the relay's contacts, from the releasing state to the operating state.
Sustaining voltage
The lowest value of the winding voltage (or current) is needed by all the relay's contacts when they remain in the operating state.
Release voltage
The highest value of the winding voltage (or current) is needed by all the relay's contacts when they are restored to the releasing state.
Actuating time
The time is needed from the beginning of the power-on of winding to the time when all the contacts go into the operating state.
Release time
The time is needed from the beginning of the power-off of winding to the time when all the contacts are restored to the release state.
The rebound time of contact
For the contacts which are closing (or opening) their circuits, the rebound time of contact refers to the time interval from the instant when the contact circuit closes (or opens) for the first time to the instant when the contact circuit finally closes (or opens).
Sensitivity
Sensitivity refers to the lowest power the coil has when the contact is switched over.
Power consumption
The power is consumed by the relay's coil to which the rated voltage is applied
The peak load
(1) The highest load current : It refers to the highest current which the relay's contact can switch over.
(2) The highest load voltage : It refers to the highest load which the relay's contact can switch over. |
