ST Series Relays

Panasonic’s ST Series Polarized Power Relays feature a high switching capacity of 8A 250VAC in either 2 Form A or 1 Form A 1 Form B contact arrangement. These Relays use Panasonic exclusive 4-gap balanced armature to realize high sensitivity, high reliability, and long life in a small package. The ST Series Relays have high breakdown voltage and surge voltage to ensure they are suitable for 250V power circuit control.

ST Series Relays are also available with terminal socket options.
