FEATURES
Standard Size 20 Package (2x2)
Flange and Servo Mounng
Up to 30,000 CPR
80 lb Maximum Axial and Radial Sha Loading
IP67 Sealing Available
The Model 702 Size 20 Accu-Coder™ is a heavy duty, extremely rugged,
reliable, yet compact industry standard 2" diameter encoder, designed for
harsh factory and plant floor environments. The double shielded ball bearings
are rated at 80 lb maximum axial and radial shaft loading to ensure a long
operating life. Made to withstand the harsh effects of the real world, both
the flange and servo models are rated IP67 with the optional heavy duty
shaft seal. With a variety of mounting options in both the flange and servo
models, the Model 702 is ideal for both new applications and replacements.
If you need an encoder that won't let you down, the Model 702 is it.
COMMON APPLICATIONS
Moon Control Feedback, Conveyors, Elevator Controls, Machine Control, Food
Processing, Process Control, Robocs, Material Handling, Texle Machines

internal resistor, 100 mA max per channel
Push-Pull – 20 mA max per channel
Line Driver – 20 mA max per channel
(Meets RS 422 at 5 VDC supply)
Index ......................... Occurs once per revolution. The index for
units >3000 CPR is 90° gated to Outputs A
and B. See Waveform Diagrams.
Max Frequency ......... Up to 1 MHz
Electrical Protection .. Reverse voltage and output short circuit
protected. NOTE: Sustained reverse
voltage may result in permanent damage.
