Astrosyn’s latest linear actuators offer high thrust, compact dimensions and an attractive price – even for small quantities
Astrosyn International Technology is launching two linear actuators that are driven by permanent-magnet (PM) stepper motors.
The use of PM stepper motors offers manufacturers the advantages of simple construction, high thrust and low price.
However, unlike most permanent-magnet devices, the minimum order quantities from Astrosyn are low, at only 100 pieces.
Both of the new models have a shaft stroke length of 12.7mm with a push/pull force of 35N. Step angles are 15 or 7.5 degrees, producing a pitch/step of 0.0254mm and 0.0127mm, respectively.
The compact units, which have a 25 mm outside diameter and weigh only 45g, have a patented end cap on their front flange to provide extra protection to the sleeve bearing.
These 12V DC actuators are said to offer advantages for a wide range of applications, such as three-way valve control in HVAC systems, antenna adjustment, emission controls, and in medical and laboratory instruments.
