The DAT71210SU is a normally open, high-voltage reed relay from the DA(UL) series, designed for high-reliability applications. It provides a high isolation of 10kV DC or AC peak across its tungsten contacts, which are capable of switching voltages up to 7000V. The relay operates with a nominal 12Vdc coil and has a maximum switching power of 50W. This model is configured for PCB mounting with M4 stud fixing and provides high-voltage connections through 0.250-inch spade terminals. Its robust specifications make it suitable for demanding equipment such as cardiac defibrillators, high-voltage power supplies, and test equipment.
