The DAT71215-HR is a high voltage reed relay from the D-HR series, designed for applications requiring high insulation resistance and high voltage switching. It provides 15kV isolation across its normally open (SPNO) tungsten contacts and operates with a 12V DC coil. This relay can switch up to 10000V at a maximum of 50W, features a minimum insulation resistance of 1x10^14 Ohms, and has a maximum contact resistance of 250 mΩ. With its high vacuum reed switch construction, it is well-suited for high-reliability applications such as cardiac defibrillators, high voltage power supplies, and sensitive test and measurement equipment.
