MicroMo's incremental shaft encoders are based on the optical or magnetic design principles. To reduce the influence of resonant frequencies, the encoders are mounted directly on the shaft or integrated into the motor itself. MicroMo Electronics encoders include integral magnetic, magnetic, optical and capacitive types. Their frequency range can reach as much as up to 250 kHz, and lines per revolution range from 10 to 2048.

Harmonic Drive offers their micro encoder series which are ultra miniature three channel incremental encoders with high resolution. Their measurement is as small as 7.5 mm in diameter, and they provide 360 pulses per revolution (1440 with quadrature) and also provides an index pulse. Single shaft and hollow shaft options are available.

Autotonics' E20S / E20HB Series are micro size Ø20mm (approx. 35g) incremental rotary encoders. Features include resolution of 100, 200, 320, 360 P/R and available to customize; maximum allowable revolution of 6000rpm; and shaft and hollow shaft built-in types available. Power supply specs. are 5VDC±5% and 12VDC±5%. The E50S-C is Ø 50mm Connector type rotary encoder series.  It features a IP65 Water-proof structure, and power supply specifications at 12-24VDC and 5VDC.
