Parker Hannifin announces the release of its MX45S linear positioner. The device is a 45 mm wide miniature screw-driven positioner, which like its predecessor, has been engineered for OEMs requiring reliable linear positioning in space-restricted applications and is available as single and multi-axis systems (x-y, x-z, x-y-z). Designed with anti-cage creep crossed roller bearings, this positioner allows users to position up to 7 kg of normal load across the available three standard travel lengths (5 mm, 15 mm and 25 mm). The product can be supplied with a high-efficiency leadscrew or a high- precision ballscrew, both of which are capable of producing 40 N of thrust at linear velocities of 20 mm/s and 30 mm/s respectively. Depending on the encoder used up to ±1µm repetability and 6µm accuracy can be achieved. In addition to the standard features designed into the MX45S, there are several options available to help match the positioner's performance to the application requirements. These options include rotary and linear encoders, digital limit/home sensor packs and the ability to order one of eleven pre-engineered multi-axis systems helping to reduce time to market compared to customer designed solutions. The positioner is designed for applications requiring small incremental movements, micron repeatability, smooth motion and high stiffness, all in an ultra-compact package, and is suited to applications such as biomedical imaging, fiber optic alignment, semiconductor inspection and laser diode research.
