Optical Quadrature Encoders
Anaheim Automation offers a selection of single-ended, differential, and high-resolution Incremental Rotary Encoders. These low-cost, ruggedly constructed encoders are available to cover shaft sizes ranging from .059" to 1" in diameter, capable of tracking up to 100,000 cycles per second, offer 32 to 2,500 cycles per revolution (CPR) and are available with an optional third index channel feature (model dependent).

Anaheim Automation offers encoder cables and centering tools, which are purchased separately.
The ENC-A2N, ENC-A3N, ENC-4APS and ENC-A5SN without Index Series are compatible with shaft sizes ranging from .059" to 1" in diameter and can be easily added to an existing application. This line of encoders features 32 to 2,048 Cycles Per Revolution (model-dependent), with each encoder powered by a single +5VDC power supply. These single-ended output encoders are designed for cable lengths up to 6 feet. It is recommended to use a shielded cable for all encoder wiring.

The ENC-A5DN and ENC-A4PD without Index Series is compatible with shaft sizes ranging from .059" to .394" in diameter. This series features 32 to 1,024 Cycles Per Revolution (model-dependent), with each encoder powered by a single +5VDC power supply. Differential inputs can offer enhanced performance by increasing both dynamic range and signal-to-noise ratio (SNR), and maximizing noise rejection. It is recommended to use a shielded cable for all encoder wiring. The differential series is ideal for cable lengths that are 10 ft. or greater.

The ENC-A5DI with Index Series is compatible with shaft sizes ranging from .079" to .394" in diameter. This series of encoders features 50 to 1,250 Cycles Per Revolution, with each encoder powered by a single +5VDC power supply. An optional third and fourth index channel feature allows for a reference point and position tracking. Differential inputs offer enhanced performance by increasing both dynamic range and signal-to-noise ratio (SNR), and maximizing noise rejection. It is recommended to use a shielded cable for all encoder wiring. The differential series is ideal for cable lengths that are 10 ft. or greater.
