The ENC-A2N is single-ended encoder that requires a minimum shaft length of .445" and maximum shaft length of .575", and is compatible with shaft sizes ranging from .079" to .394" in diameter. The ENC-A2N provides digital feedback information for motion control applications that require position, speed and/or direction control. This line of encoders is RoHS and REACH Certified.

Optical Encoder Module Update: This new transmissive optical encoder module is designed to be an improved replacement for the Avago HEDS-9000 series encoder module. This module is designed to detect rotary position when used with a code wheel. The new module consists of a lensed LED source and a monolithic detector IC enclosed in a small polymer package. The new module uses phased array detector technology to provide superior performance and greater tolerances over traditional aperture mask type encoders. Each module is resolution specific and is matched to the resolution of a code wheel. All standard resolutions offered by the HEDS-9000 series encoder module, as well as additional resolutions, are now supported by the new module. The new module operates with a single 5V supply and provides single ended outputs which are capable of both sinking and sourcing 8mA at TTL levels. An internal 0.1 uF decoupling capacitor is designed into the new module to provide enhanced noise immunity over the HEDS-9000 series encoder modules. Physically, the new module has no external wire loops which can interfere when mounting. The connector pins are 0.051" shorter than HEDS modules, while still providing .30" insertion depth.
