A single ended signal simply transmits an electrical signal, in the form of varying voltage (A, B, and Z pulses), over one wire while the other wire is grounded. Single ended is the most cost-efficient option to implement because fewer wires are required for transmitting multiple signals. However, single- ended signaling can create “noise” by design.

It very possible for our dual output encoders to have multiple PPRs. All NorthStar SlimTach encoders offer different PPRs. However, the NorthStar RimTach dual output encoders must be from the same PPR family. For example, an encoder with a 256 PPR can be paired with a 512 but not a 600.

The difference in single and dual output encoders is simple. A Single output encoders has one connector while a dual output encoder has two. Having a dual output encoder is like having two encoders contained in one housing. However, both outputs are electrically isolated from one another.

A unidirectional encoder, also known as a single channel encoder, is primarily used for speed sensing applications. A single channel encoder only generates one signal  as an output (signal A).

The index pulse signals when the encoder shaft completes a single revolution. An index pulse is used for precision homing and count verification is various applications. It is better to have an index pulse on your encoder and not need it, rather then need it and not have that option.
