WATERBURY, Conn., June 17, 2011 — The motorized SplineRail linear actuator with an integral connector is now available from Haydon Kerk Motion Solutions Inc.

Offered alone or with a harness assembly, the integral connector features a positive latch for high connection integrity and is rated for up to 3 A. The mating connector will handle a range of wire gauges from 28 to 22, a configuration that is ideal for users who want to plug directly into a pre-existing wire harness.

The device combines mechanical drive, guidance and a stepper motor actuator into a single compact component. It uses a size 17 single- or double-stack stepper motor with either a 1.8° or 0.9° motor step angle. In addition, screw leads are available from 0.05 to 1.2 in. per revolution, providing a range of performance profiles that include self-locking threads, which can support a load without external power or breaks.

The company’s SplineRail technology uses its lead screw, supported by bearings and contained within a concentric aluminum spline.

Applications include pick-and-place mechanisms and robotic assemblies in life sciences instrumentation, semiconductor equipment, business machines, and packaging and assembly, as well as a variety of factory automation applications.

When combined with the company’s range of motion control components, the linear actuator can be used to create custom systems for many types of motion.
