Miniature actuator for non-captive
applications
Applications requiring precise positioning and rapid motion are best suited for this motor, such as in medical equipment, laboratory automation, X-Y tables, and valve control
Servotechnic introduces a size 8 non-captive linear actuator from Haydon Switch, saying that this means that equipment designers and engineers now have an even more compact option for their linear motion applications The new size 8 linear actuator occupies a minimal 0.8" (21mm) space and includes numerous patent pending innovations that provide customers high performance and endurance in a very small package

More cost-effective solution than both rotary feedthroughs, which require a ferrofluid or O-rings, and magnetic feedthroughs which do not provide a positive connection
Lightweight gearheads have zero backlash
Miniature items measure as little as 33mm in diameter and are suitable for laboratory automation and semiconductor applications requiring precise positional accuracy
In fact, it says, the Haydons size 8 is by far the smallest commercially available hybrid linear actuator on the market today.
In the non-captive linear actuator design, the lead screw runs axially through the centre of the motor and must be restrained from rotating for proper operation.
This is normally accomplished by attaching the screw to a non-rotating member of the mechanical assembly.
As the internal threaded rotor rotates the lead screw will move axially but will not rotate.
This design is especially suited for long linear travel requirements and applications where the lead screw is secured at both ends and the motor translates along the lead screw.
When incorporating the latter approach, the motor must be prevented from rotating.
This non-captive hybrid linear actuator is available in a wide variety of resolutions ranging from 0.0015mm to 0.04mm per step and delivers thrusts of up to 4.5kg without compromising long life or cost.
Built for long life (several million cycles) and superior performance, the size 8 linear actuator features engineering thermoplastics in the rotor drive nut and a stainless steel Acme lead screw, which Servotechnic says have made Haydon products so popular.
With this patented design, quiet and maintenance free operation are ensured.
Applications requiring precise positioning and rapid motion are best suited for this motor.
Typical applications include medical equipment, laboratory automation, X-Y tables, automation of any kind, valve control and many more.
Servotechnic says the product is priced aggressively, and can be custom design this motor to meet specific application requirements.
