Linear voice coil actuators provide precision, linear motion over short distances. They are used in many types of control applications, from drive mechanisms in computers to robotic assembly lines.
Rotary voice coil actuators or motors provide precision, circular motion over short angles. They are used in many types of control applications, from drive mechanisms in computers to robotic assembly lines.

All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
Force constant (KF) is the force that the actuator develops per ampere-turn of coil excitation. It is specified in pounds per amp (lbs/amp) or in Newtons per amp (N/amp).
Search Logic:
User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
Torque constant (KT) is the torque that the motor develops per ampere of coil excitation. It is specified in pounds per amp (oz-in/amp) or an equivalent unit.

Restriction of Hazardous Substances (RoHS) is a European Union (EU) directive that requires all manufacturers of electronic and electrical equipment sold in Europe to demonstrate that their products contain only minimal levels of the following hazardous substances: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl and polybrominated diphenyl ether. RoHS became effective on July 1, 2006.

Waste Electrical and Electronics Equipment (WEEE) is a European Union (EU) directive that is designed to encourage the reuse, recycling and recovery of electrical and electronic equipment. WEEE establishes criteria and requirements for the collection, treatment, recycling and recovery of this equipment. It also makes producers responsible for financing these activities. For their part, retailers and distributors must provide a way for consumers to return used or obsolete equipment without charge. WEEE became effective on August 1, 2005.
