HS25A

Durable and Reliable for Industrial Use

The HS25A magnetic encoders are designed to fit shafts from 3/8″ to 3/4″ using a durable shaft insert, which can be resized by replacing or removing the insert. This flexibility allows for quick adaptation to various needs, ensuring timely availability through factories, distributors, and stockrooms.

These encoders also feature superior shaft seals, insulated bearings for motor shaft current isolation, and robust design elements that offer long-term performance in challenging industrial environments.

HS25A

Durable and Reliable for Industrial Use

The HS25A magnetic encoders are ideal for a wide range of industrial applications, offering versatility and fast adaptation to different shaft sizes. They fit shafts ranging from 3/8″ to 3/4″, with a durable shaft insert that can be resized by replacing or removing it.

This feature allows quick responses from the factory, distributors, and customer stockrooms, ensuring that your specific encoder needs are met promptly. The shaft insert also provides isolation from motor shaft currents and permits case grounding to meet NEC requirements, ensuring safe and reliable operation.

Built to withstand harsh environments, the HS25A encoders feature superior shaft seals and bearings that keep contaminants out, even through temperature cycles and exposure to liquid sprays.

The seals are protected by mechanical barriers to prevent flexing and failure, while synthetic lubricants in the bearings extend their life. Unlike many optical encoders that are vulnerable to vibration and shock, the HS25A uses unbreakable disks and a sensor-to-disk gap more than 8 times larger than the competition.

This robust design ensures that the HS25A encoder performs reliably under demanding industrial conditions, providing long-lasting and high-quality operation.

  • Simple Installation
  • Unbreakable Optical Disk
  • Up to 8192 PPR
  • Wide-Gap Technology: Up to 8X larger gap between sensor and rotor
  • Replaces Competitive Models without Rewiring
