Fairview's new line of electromechanical relay
switches consists of 44 different +12 V and +28 V designs offered in SPDT, SP3T, SP4T, and SP6T configurations that support either latching, failsafe, or normally open actuators with usable features such as indicators, terminations or TTL logic.
The final set of experiments was performed using the electromechanical relays
. Even though the goal was to reduce mechanical components of the system to a minimum, relay was chosen as an acceptable option because the mechanical part which is making the switch is completely electrically controllable and fast-enough not to introduce delays in the operation of the system.
Current transformer should provide secondary voltage rising with frequency in a way which gives stability of the value of current flowing in the electromechanical relay
and its reliable tripping.
Grabbing the lion's share of the market are the general purpose, or electromechanical relays
. The difference between a reed relay and an electromechanical relay
is basically the crux of it.
topologies include SPDT, SP4T, SP6T, and transfer switches (DPDT), all with 1E6 lifetime and SMA connections.
The most widely applicable is the electromechanical relay
because it has the largest signal range capability of the three types.
As an example of an electromechanical relay
, the Omron Electronic Components G6Y High-Frequency Relay provides at least 65 dB isolation at 900 MHz.
All 25 pins of the DB25 interface are switched via break-before-make electromechanical relays
. A, B, and Common ports are DB25 female port connectors.
(EMR) and reed relays have served automated test equipment (ATE) applications well, but they're not likely to satisfy their needs in the future, as ATE manufacturers strive to increase channel densities in a smaller system footprint and as more tests need to be performed, faster, on devices under test.
