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.
