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.

Timing Diagram

- CPR
- The number of Cycles (C) of the A or B outputs Per Revolution.
- Index (I)
- The index output goes high once per revolution, coincident with the low states of channels A and B, nominally 1/4 of one cycle (90°e).
- One Shaft Rotation
- 360 mechanical degrees.
- One Electrical Degree (°e)
- 1/360th of one cycle.
- One Cycle (C)
- 360 electrical degrees (°e). Each cycle can be decoded into 1, 2, or 4 states, referred to as x1, x2, or x4 resolution multiplication.
- PPR
- The number of resolvable Positions Per Revolution of the encoder disk with x4 quadrature decoding.
- Quadrature (Z)
- The phase lag or lead between channels A and B in electrical degrees, nominally 90°e.
- Symmetry
- A measure of the relationship between (X) and (Y) in electrical degrees, nominally 180°e.
