One. Damage to glass insulators

Because the glass insulator of Omron relay is mainly made of metal prongs and glass sintering, it is easy to be damaged in the process of cleaning, maintenance, assembly, etc., such as pin bending, falling block, cracking, etc., which causes the performance of Omron relay to be reduced and affects the reliable on-off of Omron relay. This kind of fault situation requires careful handling during inspection, assembly, transportation and cleaning.

Two. Faulty coils

In the use of Omron relays, improper assembly and soldering can lead to the failure of the coil. When the electromagnetic system is riveted, the inappropriate adjustment pressure will bring about local damage to the Omron relay, such as too much pressure will lead to damage to the coil or coil frame, such as the disconnection of the coil, the rupture of the coil frame, deformation, winding breakdown, and affect the use effect of the relay. If the pressure is too small, it will cause the winding to loosen and the magnetic loss to increase. When welding, coil welding errors can also lead to local failures during Omron relay operation. Therefore, care should be taken when assembling and welding Omron relays, otherwise it will lead to failure.

Three. The parameters are unstable

Because most of the parts of Omron relays are riveted, there will be certain potential hidden dangers, mainly manifested in the loose or poor bonding strength of Omron relay riveting, resulting in the instability of Omron relay operation, in the actual operation of the parameters will be unstable, high and low temperature environment parameters fluctuate greatly, poor impact resistance, mechanical vibration resistance, these phenomena reduce the performance of Omron relays. The main reasons for this failure are inaccurate installation, improper placement of parts, unqualified rivet quality, and unqualified mold quality. Therefore, it is necessary to strictly control the assembly process of relays and improve the inspection level of relays.
