Sensata Technologies Reed Relays DAR72475FU

The DAR72475FU is a UL-approved, normally open, high-voltage reed relay with 7.5 kV isolation between contacts and a 24 VDC coil. It features tungsten contacts capable of switching up to 5 kV DC or AC peak at 2 A, with a maximum switching power of 50 W. Contact resistance is 250 mΩ max (typical 100 mΩ). The relay has a coil resistance of 780 Ω, an operate time of 3.0 ms, and a release time of 2.0 ms with a diode fitted. Isolation between coil and contacts is 17 kV. It is PCB mountable with flying leads for high-voltage connections and operates within a temperature range of -20 °C to +70 °C. Physical dimensions include mounting holes at 50.8 mm ±0.2 mm centers with clearance for M4 studs.
