The performance of electronic relays can be impacted by various environmental conditions. An accumulation of contaminant particles and debris between the relay’s coil and contacts is a common occurrence and will damage the relay and affect performance. Regular maintenance is required, and relays will need to be replaced from time to time.

A Common Cause of Breakdown of Electronic Relays

Another common problem relays experience is a failure due to excess voltage. A relay, like other electronic components, has a maximum voltage it is designed to tolerate. If that voltage is exceeded, a catastrophic failure can result. The maximum voltage a relay can accommodate is referred to as the breakdown voltage. Repairing this type of problem can be expensive and time consuming.

Because relays can and do break down due to various factors, it is advisable to keep a supply of obsolete relays on hand to use as replacement parts. Obsolete electronic relays that can tolerate the voltage requirements of an application are inexpensive and widely available components, which companies can either keep in stock or can order from a distributor in the event of a malfunction.

Independent online distributors of obsolete electronic components specialize in the sale of relays and other electronics to companies that can use them in their own applications. Their prices are typically quite low, much lower than suppliers of new components and their selection is wider too. Practically any product can be located online, even hard-to-find electronic relays. If you have excess inventories of electronic relays your company needs to dispose of, the same independent distributors act as inventory buyers. They will purchase your unused, excess inventories and resell them at low prices to their customers.
