Electrical Interface
Pull up resistors on output pins 2, 3, and 5 have already
been integrated into the mid-sized encoder. Each of the
three encoder outputs can drive a single TTL load in this
con guration.
Connectors
The connector to be used with the mid-sized encoder
is Molex Part Number 51021-0500. This is a 5 connector
crimp wire to board connector.
The connector used on the encoder is orientation proof
type, 2 di erent cables con guration required for connec-
tion to right angle and axial angle type encoder.
