Miniature rotary encoder boasts high resolution and built-in brushless dc motor commutation

By Lisa Eitel | August 9, 2019

Quantum Devices Inc. now offers a new miniaturized commutating/incremental optical encoder option. The new QM22 series of incremental encoders offers a super compact 22-mm diameter and a 12.4-mm thickness. These are suitable for high-volume OEM applications and fit on NEMA 11 BLDC servo motors.

The QM22 offers high resolution and a great variety of electrical commutation options.

Along with its miniature form factor, the unit works for high-precision positioning and is available with line counts up to 2,500. Multiple integrated commutation output options — including 4, 6, or 8-pole configurations — eliminate the need for additional external commutation peripherals such as Hall boards.

Immunity from EMI/RFI noise means the QM22 series excels in an especially wide variety of applications.

The QM22 miniature incremental encoder consists of a modular, bearingless design that features an easy to install Lock-n-Twist assembly method. With its hermetically sealed LED and Quantum’s patented sensor design, the QM22 optical encoder is designed to maximize performance and reliability in its miniature package. The QM22 is also REACH and RoHS compliant.

For OEMs with existing designs that use the now obsoleted Heidenhain/Renco R22i encoder line, the QM22 is a suitable replacement. Attractive OEM pricing, reduction of assembly time and elimination of ancillary commutation devices are the top benefits of the super compact QM22 encoder.

Quantum Devices Inc. is an ISO 9001:2015 certified company that specializes in design and development of standard and custom high-performance incremental encoders. Vertically integrated manufacturing ensures full control of product quality based on expertise in photodiode fabrication, electrical assembly, injection molding, and metal component machining.
