Many types of relays exist, but only a few are suitable for ATE applications. Among the more common types are electromechanical (armature) and dry reed. The table below compares some key parameters of these two relays.
Relay Type |
Isolation (El) |
Speed (ms)* |
Power (VA) |
Life at rated load |
Electro-mechanical |
10^7-10^14 |
2-6ms |
1-750 |
10^5-10^7 |
Dry Reed |
10^7-10^14 |
0.5-1ms |
0.5-60 |
10^5-10^7 |
* Speed (ms) represents Operate Time - does not include bounce time.
Marvin Test Solutions' switching products use both types of relays to offer the best benefits for ATE applications.
