Application notes
MOUNTING DISTANCE BETWEEN RELAYS
Applicable to XL, X, XA, XCL, XC,

Definition and applicability
This application note defines the minimum distance between relays to insure relay performance as specified in our
data sheets.
Phenomenon analysis
Each relay generates a magnetic field either when the relay is de-energized because of the permanent magnet or
in the energized position because of permanent magnet and coil. The magnetic field generated by one relay could
affect the performance of another relay when the below minimum distance between relays is not respected. If the
relays are mounted adjacent to each other, it is advisable to alternate direction of magnetic path on every other unit
and to keep a 1/16-inch space between relays (figure “A”). Or when mounted in the same direction, separate each
relay from the other by 1/8 inch (figure “B”). If two or more rows of relays are installed, allow clearance of 1/8 inch
between rows, (figures “C” and “D”). Provide 3/16-inch space between relays if used in opposition (figure “E”).
