From printers to robotic arms, optical encoders tell devices when, how and where to move when performing a function. GMN understands the importance of high-quality components and has focused on producing custom optical encoder media to achieve superior incremental movement accuracy and component durability for leading global brands including HP, Epson and Avago Technologies.
Types of encoders
Used to measure rotations, disk encoders are a critical to the functionality of devices that use them. GMN ensures the precision needed to manufacture a quality disk encoder.
These linear encoders measure linear motion or speed. GMN’s engineering team can help develop the right construction for the life of your encoder.
Long encoder strips
Long encoder strips are required in large devices such as large format printers. GMN has extensive experience working through the complex manufacturing required to produce long encoders.
GMN encoder component advantages
- Use of polyester film for added durability and lower cost
- Long strip encoders to enable large format printing
- Available stainless steel bands to provide stability and reinforcement for the length of the encoders
- Technical imaging to create highly exact images on optical wheels or strip encoders
- Mechanical stiffeners to prevent warping during acceleration
- Unassembled motor, sensor and encoder components for custom application motion controls
GMN produces optical encoders in a variety of materials and formats to meet our clients’ exacting standards. We meet ISO 9001:2003 quality standards to manufacture encoding components for a wide variety of industries.
