Obsolete Contactor Coils

The contactor, along with its operating coil, is an integral part of industrial manufacturing today. Precise machinery and motor control has revolutionized the way we manufacture just about every product in an industrial environment and the contactor coil, in most cases, is a critical part of that system. However, obsolete contactor coils open up a new page in the book of down-time.

When they operate properly, they provide us with the ability to isolate and step up power to motors and other higher current devices using a variety of control voltages. When they fail, they can leave us helpless in a costly situation on the factory floor.

Contactor Coil Trackdown and Troubleshooting

Fortunately, contactor coil problems can be fairly simple to diagnose, sometimes the bigger issue is finding a drop-in replacement for an obsolete contactor coil in an environment where ever-changing technology and design can phase out, or completely eliminate models from the available parts catalog annually.

For ease of use, accessibility, and available industrial contactor coils, we've been referring individuals to eBay. It almost seems too easy but we've found many parts available that we thought we'd never find. Even after checking with larger parts houses, we still come back and check here regularly. It is not unusual to find obsolete Allen Bradley contactor coils, Westinghouse contactor coils, Square D contactor coils, or obsolete GE contactor coils listed daily. Many times you can stumble on vintage Cutler Hammer coils or even coils with less popular voltages like 48V, 250V, 300V, or 480V.

These parts are those that were posted as a result of hard times at other companies and in many cases are NOS (new old stock).

Machine downtime due to an obsolete contactor coil is a reality for many. There are options, however, nothing is ever easy. Here is a systematic approach, a simple yet effective method in dealing with a failed component that has likely been phased out by the manufacturer and no longer readily available.

1. Identify your problem... Making a positive identification of the failed component is the crucial first step. Troubleshooting is not a synonym for guess-work. It is a scientific method of determining a problem. There should be no doubt as to the source of the problem. This is determined through testing and not guessing.

2. Check the shelf... That's right, all too many times has a spare component or unit been passed over and found a day late. It sounds simple, but it is always the next step. Don't go looking for something that doesn't need to be found.

3. Check with the manufacturer... A website visit, email, or quick phone call to inquire about a a drop-in replacement is common sense. This step will deliver the bad news if obsolescence is indeed the case.

4. Check eBay... Believe it or not, this has become somewhat of a flea market for old industrial parts. By many, it is still considered to be a website for collectibles and the like, but a quick search can actually reveal a different side to the 'bay. Many private sellers post industrial components as a buy it now type listing, therefore bypassing the auction format all together.

Take a moment and browse the eBay listings since they are always changing...

5. No positive results? explore other options... If your particular contactor coil is ultimately deemed obsolete and unavailable, you'll need to take the next path of least resistance. This may be upgrade or update your equipment with newer components. The good news is that your machinery or industrial equipment will most likely not need complete re-engineering or a top-to-bottom overhaul to accomodate new components. Adjustments to your system are possible when there is no other choice.
