Miniature Rotary Encoder Package with Big Benefits
July 29, 2019
Quantum Devices, Inc. is announcing a new step forward in miniaturization of commutating/incremental, optical encoder technology. The new QM22 series of incremental encoders offers a super compact 22mm diameter and a 12.4 mm thickness. Ideal for high volume OEM applications and fits on a NEMA 11 BLDC servo motor. The QM22 offers high resolution and a great variety of electrical commutation options.
Miniature Optical Encoder with High Resolution & Built-in Brushless DC Motor
Along with its miniature form factor, the unit is capable of high precision positioning and is available with line counts up to 2500. Multiple integrated commutation output options including 4, 6, or 8 pole configurations eliminate the necessity for additional external commutation peripherals such as Hall Boards. Immunity from EMI/RFI noise greatly extends the range of suitable applications in which the QM22 series can be incorporated.
Features & Benefits
The QM22 miniature optical rotary encoder offers several advantages:
- Modular, bearingless design
- Easy to install Lock-n-Twist method reduces assembly time
- Hermetically sealed LED
- Patented sensor design
- High noise immunity
- REACH & RoHS compliant
- Elimination of ancillary commutation devices with built-in BLDC motor commutation signals
- Attractive OEM pricing
For OEMs with existing designs that utilize the now obsoleted Heidenhain/Renco R22i encoder line, the QM22 is an ideal replacement.
Quantum Devices offers drop-in replacements for many Renco and Heidenhain models:
Additional tiny rotary encoders manufactured by Quantum Devices:
