TE Connectivity / Schrack Force Guided Relays SR6 Next Generation
TE Connectivity's (TE) Schrack Forced Guided Relays SR6 Next Generation (SR6nG) features force-guided contacts that monitor contact state with 99% diagnostic coverage, which is ideal for designing safety circuits. The contacts are insensitive to voltage peaks and can withstand short-circuit currents up to 450A. TE Schrack Forced Guided Relays SR6nG offers a minimum contact load of 5V/1mA, which allows direct monitoring through controller input, and a sensitive monostable magnetic coil system to reduce heat generation.
