E4T

Description

The E4T miniature transmissive optical encoder is designed to provide digital
quadrature encoder feedback for high volume, limited space applications. The
E4T is designed to be a drop in replacement for the E4P that offers higher
maximum speed and increased output drive. The E4T utilizes an innovative,
push-on encoder disk which accepts shaft diameters of 2.0mm to .250".
The E4T miniature encoder base provides mounting holes for two #3-48, length
3/16" or two M2.5, length 4mm screws on a .586" bolt circle. The encoder cover
is easily snapped onto the base and is marked with the connector pin-out.
The E4T series encoder is connected using a 4-conductor, high retention,
polarized, 1.25mm pitch connector. Mating cables and connectors (see the
Cables / Connectors web page) are not included, and are available separately.
