In kit form their high speed incremental encoders are available 2500 PPR to 400kHz, and in housed form to 1000 PPR and 1mhz is available.

RSF Electronics offers a wide range of enclosed and open linear encoders, and rotary encoders. The enclosed models are best suited for harsh environments, with extra protection (IP 64) available for very harsh environments. They feature resolution from 5 µm to 0,1 µm. The non-contact open encoders have resolution ranging from 10 µm to 0,05 µm.Depending on the version of the measuring system, two different measuring scales are available: glass (partially ROBAX glassceramic) or steel. They offer several rotary encoder series, features of some of these systems include up to 7.200.000 counts per revolution.

Photocraft manufactures a full line of incremental and absolute rotary encoders. These include shaft encoders, hollow shaft, programmable and wheeled encoders. Their single-turn, absolute encoders provide up to about 10-bit resolution and are vailable in low cost miniature, modular and industrial configurations. Programmable encoders (available on many models of shaft, hollow shaft and wheeled encoders) allow you to select pulses per revolution, output circuit, and other features at installation time.

Turck offers a complete line of incremental and absolute encoders - shaft/hollowshaft and multi- and single-turn. Features of their Kubler line include temperature and aging compensation, plus improved EMI, vibration and shock resistance.

Electronic Machine Parts' encoders feature a dual-bearing design and are shock resistant. They are available with shaft sizes of 3/8" on size 25 and 35 encoders, 1/4" on size 15 encoder, and special sizes upon request. Standard line count is at 1024, with other available line counts from 32 to 1250.
