Supported types

Digital incremental and BiSS absolute

Power

5V at 250 mA max. is available to power the encoder, protected by self-resetting fuse.

Connection

Female 26 way high density D-Sub.

Encoder connects via adapter cable according to encoder type.

Adapter cables for supported encoders are available from AML.

Incremental encoder support
