20-30 Volts

We developed an underwater version, the DA 22-SUB, based on the DA 22 actuator. The DA 22-SUB is waterproof down to a depth of 100 meters (10 bar / 145 psi).

The housing is CNC machined from marine bronze (DIN 1705 R65/MIL B24480). The integrated overload coupling (ISS system) protects the solid-steel gear train from every kind of radial shock loads.

The standard version (PWM) of the DA 22-SUB comes equipped with analog position feedback and an integrated moisture and temperature sensor. Every actuator is tested in our test lab for six hours in a pressure tank under various atmospheric pressures (0 to 15 bar). Customized variants on request.
