DESCRIPTION
The LM, LX, and LQ series provide reliable low-power switching for telecom and general purpose loads. The
bifurcated contacts are a silver alloy with a gold cap so that loads from microamps to 2 Amps can be switched.
Due to the highly efficient magnetic structure, a low coil power of 140 to 300 mW is needed to drive these relays.
These relays also have UL and CSA listing at 2 Amps and meet FCC part 68 surge strength of 1500 Volts.
