The ENC-A4TD is a miniature differential encoder designed for high-volume applications with space limitations. The ENC-A4TD accepts a minimum shaft length of 0.275" and maximum shaft length 0.395". Shaft sizes ranging from 0.079" to 0.250" in diameter. When attached to the end of a shaft, the encoder provides digital feedback control using an encoder module designed to detect the rotary position with a code wheel. This differential encoder consists of an LED source lens and a monolithic detector IC enclosed in a small polymer package. These modules implement phased array detector technology providing superior performance and tolerances over traditional aperture mask type encoders. The ENC-A4TD series provides digital quadrature outputs on all resolutions and are capable of sinking or sourcing 8 mA each. These encoders are powered from a single +5VDC power supply and are RoHS compliant and REACH Certified.
