Project: 12-volt Power Connector Replacement

Orange power connectors

The orange and red power connectors for 12-volt systems that have been stocked in the HIF warehouse are no longer available from the manufacturer. The manufacturer's mold is broken and they have informed HIF that they do not plan to make these connectors in the future. These connectors have been supplied by HIF and used on 12-volt power systems since the early 1980's. There are literally several hundred thousand of these in use at USGS hydrologic monitoring stations across the U.S.

A market search will continue until Dec. 31, 2008 for additional sources of supply for the 18 AWG (orange) connectors. If none are found, a search for a suitable replacement connector will be conducted.

HIF presently has a 2 1/2 yr. supply of 18 AWG (orange) connectors and a 10 year supply of 22 AWG (red) connectors. As of late March, 2010 a replacement has been designed and a procurement action to manufacture the replacement is in process.
