Mechanical Tolerances (Conforms to EIA Standard RS-217)

• Exterior dimensions A and B are held to maximum tolerance only to insure overall enclosure fit.
• Dimensions D and E are held to  ± tolerance to insure magnetic qualities under all applications.
• Window dimensions F and G are held to a minimum tolerance only to insure coil fit.
• Dimensions K and R are reference dimensions only.

measurment:

• Dimension D is measured by caliper at any point on either core half.
• Dimension E is measured at the butt joint.
• Dimensions F and G are measured at the shortest point but at least twice the radius R from the edge of the window.
