Optical Encoders
SPECIFICATIONS
Electrical Ratings
Input Voltage: 5.0 ± 5% Vdc or 5-26 Vdc
Input Current Requirements: 40 mA
maximum plus interface loads
Ripple Current: 2% peak-to-peak @ 5 Vdc
Output Circuits: TTL Compatible
VOH >3.80v@-8mA, VOL<0.44v@8mA
VOH >2.50v@-20mA, VOL<0.50v@20mA
Output Format:
Gray code or Binary Code: 8-bit, single turn,
single ended. Gray code option utilizes low
true Chip Enable (CE’) that is pulled down with
internal 10K resistor. Positive TTL signal to
CE’ will force the 8-bit outputs to tri-state
condition allowing for shared data paths
between
encoders,
easing
basic
microprocessor bus interfacing.
Frequency Response: 50 kHz
Output Count Increase: Clockwise rotation
(Option A); counter clockwise rotation
(Option B) See ordering information.
Positional Accuracy: ±0.5 LSB maximum
error
Mechanical Ratings
Maximum Shaft Speed: 8,000 RPM
Shaft Diameter: 0.125" (3,175mm)
Shaft Material: Stainless steel
Bearings: Radial ball bearing, R2 type
Radial Shaft Load: 2 lbs maximum
Axial Shaft Load: 1 lb maximum
Housing: Carbon fiber composite (case
ground via connector)
Housing Volume Resistivity: 10-2 ohm-cm
Termination: 8" 12-conductor ribbon cable
with 2x7 connector
Mounting: Servo
Moment of Inertia: 9.5x10-6 oz-in-sec2
Acceleration: 1x105 radians per second2
Environmental Ratings
Operating Temperature Range: 0 to 70°C
typical; -20°C to 100°C optional (contact
Grayhill for more information)
Thermal Shutdown: Tambiant max. vs.
input voltage max. 40C°= 25.0v, 60°C =
20.0v, 80°C = 15.0v, 100°C = 10.0v (Total
load currents=30 mA)
Storage Temperature Range: -40°C to
125°C
Humidity: 98% non-condensing
Vibration: 20g @ 50-500 CPS
Mechanical Shock: 50g @ 11mS duration
