Sensata Technologies Reed Relays DAR70505FU

The DAR70505FU is a UL-approved, normally open high-voltage reed relay with 5 kV isolation between contacts, rated for switching up to 1000 V DC or AC peak and 3 A DC or AC peak, with a maximum carry current of 4 A. It features a rhodium contact material for low contact resistance, a 5 V DC coil with 28 Ω resistance, and operates with a 3.0 ms operate time and 2.0 ms release time when a diode is fitted. The relay supports PCB mounting with flying leads for high-voltage connections and maintains contact-to-coil isolation of 17 kV. Operating temperature range is -20 to +70 °C, with dimensions of 50.8 mm ±1 mm and mounting holes at 50.8 mm ±0.2 mm centers for M4 studs.
