H2W Technologies offers miniature versions of both our moving coil and moving magnet voice coil actuators. Additionally, we offer custom designed solutions to meet your application specifications.
H2W has built its smallest moving magnet voice coil actuator (NCM01-04-001-2IB) to date, with an outside diameter of 0.40 in [10 mm and a length of 0.735 in [18.8 mm. It has a stroke of 0.10 in [2.5 mm and generates a continuous force of 0.10 lbs [0.45 N and a peak force of 0.30 lbs [1.35 N. It weighs just 0.20 ounces [5.7 grams. This actuator utilizes a hardened shaft and sliding contact bushing to ensure long life, and 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.
Our 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. It has a 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. It weighs just 0.20 ounces [5.7 grams. The bobbin has been constructed of plastic to prevent any damping forces that a metallic bobbin would create. The compact design allows the actuator to be used in a number of handheld applications.
