ACML-7420 Units Conditions
Minimum External Air Gap
(Clearance)
L(101) 8.1 mm Measured from input terminals to output terminals,
shortest distance through air.
Minimum External Tracking
(Creepage)
L(102) 8.1 mm Measured from input terminals to output terminals,
shortest distance path along body.
Minimum Internal Plastic Gap
(Internal Clearance)
0.05 mm Through insulation distance conductor to conductor,
usually the straight line distance thickness between the
emitter and detector.
Tracking Resistance
(Comparative Tracking Index)
CTI >175 V DIN IEC 112/VDE 0303 Part 1
Isolation Group IIIa Material Group (DIN VDE 0110, 1/89, Table 1)
All creepage and clearance pertain to the isolation component itself. These dimensions are needed as a starting point
for the designer when determining the circuit insulation requirements, and not re ective of the equipment standard
requirements.
