H2W Technologies offers miniature versions of both their moving coil and moving magnet voice coil actuators. Additionally, they offer custom-designed solutions to meet application specifications.
This actuator uses a hardened shaft and sliding contact bushing to ensure long life. It is ideal for oscillatory motion. The compact design allows the actuator to be used in a number of handheld applications. Moving magnet voice coil actuators have built-in bearings so there is no need for the customer to add mass or complexity to their motion system to integrate a bearing, and there are no moving leads to worry about cable management.
- Smallest moving coil voice coil actuator (NCC01-04-001-1X) has an outside diameter of 0.44 in [11.1 mm] and a length of 0.36 in [9 mm]
- Stroke of 0.13 in [3.2 mm] and generates a continuous force of 0.06 lbs [0.27 N] and a peak force of 0.18 lbs [0.8 N]
- Weighs 0.20 ounces [5.7 grams]
- Bobbin has been constructed of plastic to prevent any damping forces that a metallic bobbin would create
