Application notes N°023



MOUNTING DISTANCE BETWEEN RELAYS
Applicable to M2XX / M3XX / M4XX / M5XX


Definition and applicability
This application note defines the minimum distance between relays to maintain the whole performances of the relays as given in our data sheets.

Phenomenon analysis
Each relay generates a magnetic field either when relay is de-energised because of the permanent magnet or in the energised 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 relay 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 1.6 mm space between relays, figure “A”. Or when mounted in the same direction, separate each relay from the other by 3.2 mm, figure “B”. If two or more rows of relays are installed, allow clearance of 3.2 mm between rows, figures “C” and “D”. Provide 4.8 mm space between relays if used in opposition, figure “E”. Distance in millimetre.
