E16 Product Description
The E16 16mm micro optical encoder is designed to provide A, B and Index digital quadrature signals for high volume, restricted space applications. The E16 utilizes an innovative, push-on encoder disk which accepts shaft diameters of 1.5mm and 2mm.
The E16 is designed to be a one-time installation micro optical encoder, the base provides mounting holes for two M1.6-0.35, length 3mm screws on a 10mm bolt circle. The encoder cover is easily snapped onto the base and is marked with the connector pin-out.
The E16 series encoder is connected using a 5-conductor, polarized, 0.8mm pitch connector (Hirose part number DF52-5P-0.8C). Mating cable (see the Cables web page) is not included and is available separately.
Please Note: Due to the E16's design, it is recommended for use as a one-time installation.
