Haydon Kerk Motion Solutions Inc. has introduced a microslide linear actuator touting a resolution of 15?/step (0.0006in/step) and a maximum load of 13N (3lb-f). This device is ideal for applications requiring precision motion in a small footprint and is optimized for applications such as microfluidics and optical positioning.

The Haydon Kerk Microslide is about 22 x 25.2mm and is capable of up to a 64mm maximum stroke length. A lightweight anodized aluminum base plate houses the lead screw bushing and is rigidly attached to the aluminum motor mounting plate, described the company. At the heart of the slide is the Haydon 15000 Series 15mm can-stack motor. The LS15 stepper motor requires no complicated controls and can be commanded using a simple pulse and direction signal.

The device boasts a maximum load of 13N (3lb-f).

The slide load carriage is made from self-lubricating polyacetal and features a built-in clearance take-up mechanism for load rigidity during motion. The carriage is supported by stainless steel guide rods coated with Black Ice TFE coating. The Kerk leadscrew is 303 stainless steel and is available in five different leads including 0.3mm, 0.4mm, 0.5mm, 1mm and 2mm. When combined with the LS15 stepper motor, very fine positioning resolution can be achieved with the microscrew, noted Haydon Kerk.

The microslide is easily configured for application-specific requirements including custom mounting, different stroke lengths up to 64mm, magnetic or optical position sensors, and custom wire harnesses.
