8 / 15 page 8 Electrical Characteristics Electrical Characteristics over Recommended Operating Range, typical at 25 °C. Part Number Symbol* Min. Typ. Max. Units Notes HEDS-6500 Icc 17 40 mA VOH 2.4 V IOH = -40 µA max VOL 0.4 V IOL = 3.2 mA tr 200 ns CL = 25 pF, RL = 11 kΩ pull-up. tf 50 ns HEDS-6540 Icc 30 57 85 mA VOH 2.4 V IOH = -200 µA max VOL 0.4 V IOL = 3.86 mA tr 180 ns CL = 25 pF, RL = 3.3 kΩ pull-up. tf 40 ns *Explanation for symbols. Icc – Supply current, VOH – High Level Output Voltage, VOL – Low Level Output Voltage, tr – Rise Time, tf – Fall Time. Electrical Interfaces To insure reliable encoding performance, the HEDS-6540 three channel encoder requires 2.7 k Ω pull-up resistors to the supply voltage on each of the three output lines Ch. A, Ch. B, and Ch. I located as close as possible to the encoder (less than 4 feet). Parameter Symbol Dimensions Tolerances [1] Units Moment Of Inertia J 7.7 (110 x 10-6) gcm2 (oz-in-s2) Required Shaft Length [2] 15.9 (0.625) ± 0.6 (.024) mm (inches) Bolt Circle [3] 46.0 (1.811) ± 0.13 (.005) mm (inches) Mounting Screw Size [4] 2.5 x 0.45 x 5 mm Pan Head Style #2-56 x 3/16 Inches Encoder Base Plate Thickness 3.04 (120) mm (inches) Mounting Screw Torque 1.0 (0.88) Kg (in-lbs) Hub Set Screw UNC #2-56 Hex head set screw Notes: 1. These are tolerances required of the user. 2. Through hole in the encoder housing are also available, for longer shafts. 3. The HEDL-65X0 must be aligned using the aligning pins as specified in the section on “MOUNTING CONSIDERATIONS.” 4. The recommended mounting screw torque for 2 screws is 1.0 Kg (0.88 in-lbs).
