NEC's new generation EF2 relay, exclusively available from IMO, is one of the world's first 50mW signal relay, with power consumption around a third of the previous lowest power relay (140mW).
NEC's new generation EF2 relay, exclusively available from IMO, is one of the world's first 50mW signal relays, with power consumption around a third of the previous lowest power relay (140mW).
This represents a major technological advantage for the global telecommunications industry, with the significant reduction in power rating enabling the EF2 to be driven directly by the output of a CMOS IC without the need for driver circuitry, which in turn reduces costs and bulk.
In addition to saving crucial weight, space and money, the relay boasts ultra high sensitivity and reliability, achieved by optimising magnetic circuit parameters such as armature travel, core cross section and magnetic pole area using accurate magnetic simulation.
Furthermore, the EF2 relay has a reduced mounting space of 15mm x 7.5mm and features non-latching, single- and double-coil latch type relays.
Capable of withstanding 1500 VAC and 2500V surge voltage (2 x 10_s) between coil and contact, the relay meets FCC Standard part 68, is UL recognised and CSA certified, and is conveniently available in tube or tape packaging.
A through-hole version, ED2, is also available for applications unable to take advantage of surface mount construction.
