Small powerful relays still the choice for telecoms

19 May 2004 Switches, Relays & Keypads

Major innovations in recent years have revolutionised electro-mechanical actuated telecommunications relays. In spite of a noticeable reduction in their physical size, all significant characteristics have actually been improved. Their outstanding reliability and their legendary robustness still make relays the first choice for switching in telecommunications.

Axicom's IM Relay with a size of 10 x 6 x 5,65 mm only, is said to be the smallest and most efficient telecom/signal relay on the market. Its innovative technology allows a slim line and low profile relay in one design. The IM Relay combines minimum board-space and minimum height in one relay.

Three different versions of IM relays are available, one through-hole type and two surface mount types, a J-Leg and a Gull Wing version. The relays are capable of withstanding soldering conditions with a maximum temperature of up to 255°C. Hence the IM Relay is suitable for all current soldering techniques. The small size and as a consequence, the low weight, allows the assembly of relays on the board with all the standard high speed pick-and-place machines.

The IM relay covers the global requirements on telecom relays regarding agency approvals and safety requirements. The IM relay is the first relay which is approved according to the IEC 61811-55 standard for 4th generation telecom relays.

Available coil voltages are: 1,5, 3, 4,5, 5, 6, 9, 12, 24 V; power consumption: 140 mW/200 mW; and rated contact load: 60 W/62,5 VA with rated current equal to 2 A.
