　　Triconex 3721 Frequently Asked Questions

    　Is it hard to find 3721 units?

Some of the parts on Triconex Parts can be very difficult to find. A great deal of them have reached end-of-life status and are therefore no longer in production. Aotewell Automation will make every effort to locate the 3721 in response to your quote request, and we will be able to get you better pricing if no one stirs up the market.

　　What is meant by “stir up the market”?　Why is it a problem?

Stirring up the market is the result of many different suppliers all receiving requests to locate a certain part. It makes other suppliers believe the part is in much higher demand than it might actually be, resulting in raised prices and lower availability. To keep costs down and ensure a smooth transaction, Aotewell Automation recommends requesting quotes from suppliers in a limited, stragegic manner.

　　When should I expect to receive the 3721?

The 3721’s availability will be the primary determining factor for lead time. We will check with our trusted suppliers in the event that we do not currently have the 3721 in our inventory. Lead time may also be affected by additional services performed, such as repair or refurbishment.
