Q:
What new technologies are influencing electromechanical relay design?
18 answers
Answers:
1.High thermal rating for the winding wires. 2.Bi-metal contacts in place of silver contacts. 3.Mild steel components in place of the nickel iron (like armature, yoke and core) with better and innovative design. 4.Simple approach of the coil design for the induction coils for the Electrical reset relays. 5.Innovative and indigenous design for the flags.

Especially for high end applications, overall size, high reliability switching applications necessitates hermetic seals which in turn calls for utilizing laser weld technologies. Also test requirements such as vibration,shock,fine leak tests,automated test equipments are requirements for MIL grade relays.

MEMS, MEMS, MEMS. It is the only new thing in the world of EM relays in decades. They will replace most EM relays, I expect, within 10 years.
~Dan H, Research & Development, Long Beach, CA
Miniaturization, relay with built in multi fuses, latching relays for power saving are major concepts for new designs.

Q:
From your perspective, which companies are creating the most innovative electromechanical relays?
18 answers
Answers:
OMRON and XCOM are making MEMS devices. Coto has done a good job of cost reducing and miniaturizing reed relays. I don't see much out of the other suppliers that is all that successful, as the surface-mountability and RF performance of true EM relays is still pretty bad for anything in the tens of dollars range.
