Bourns announced the release of three new series of incremental potentiometers: the Bourns PST065 Series 6 mm, PST10 Series 10 mm and PST155 Series 15 mm. These compact hollow-shaft position sensing solutions are designed to deliver accurate rotary position feedback, long-term reliability and maintenance-free operation in industrial and commercial equipment.
The series combine space-saving mechanical designs with contact sensing technology. They provide stable analog output throughout their service life while eliminating mechanical wear associated with conventional contact potentiometers. Hollow-shaft configurations simplify mechanical integration, and the compact packages support space-constrained designs. Horizontal and vertical PC board mounting configurations are available across the series, with a standard resistance range from 1 kΩ to 5 MΩ.
“The PST10 Series expands our position sensing portfolio with a compact solution that helps customers improve reliability and reduce maintenance in applications requiring rotary position feedback,” said Javier Navarro, Product Line Manager, Sensors & Controls, Bourns. “Its contact sensing technology and hollow-shaft design simplify mechanical integration while providing consistent electrical performance over an extended operating life.”
“Designers of compact control and position feedback systems often need to balance limited available space with requirements for long operational life and stable performance,” Navarro said regarding the PST065 Series. “The PST065 Series combines a 6 mm package size, a hollow-shaft mechanical design, and a 10,000-cycle rotational life rating to help simplify integration into industrial controls, motion systems, and other equipment where long-term reliability is an important design consideration.”
“Position feedback components used in industrial equipment must maintain consistent electrical characteristics while fitting within increasingly compact mechanical designs,” Navarro added for the PST155 Series. “The PST155 Series combines a 15 mm hollow-shaft configuration, multiple mounting orientations, and a 10,000-cycle rotational life rating to support automation and control equipment that requires dependable rotary position sensing over extended operating periods.”
