Mueller was founded in 1908 by Ralph S. Mueller, the inventor of the alligator clip. Located in Cleveland, Ohio, the Company has held numerous patents on early alligator and electrical test clip designs. For over 95 years, Mueller has been the world's only manufacturer of a complete line of electrical test clips and insulator boots. In the 1980s Mueller added a full line of test leads and electronic test and measurement accessories to complement its line of electrical test clips. The Company also developed custom test leads for leading manufacturers of electronic test tools, test and measurement equipment, and electrical testers, such as for Agilent, Tektronix and Fluke meters and multimeters. It rounded out its test lead and patch cord line to include a full solution of test lead kits, grabber test clips, test probes, spade terminals, banana plugs, banana jacks, coaxial cable assemblies and BNC connectors.
As a supplier to leading electronic test and measurement equipment manufacturers, Mueller's test leads are designed for compatibility with electronic test tools and electrical testers produced by the leading meter manufacturers, including Tektronix, Agilent and Fluke. Mueller's products for test equipment connection are a safe and reliable replacement test lead for meters by leading electrical and electronic test and measurement equipment manufacturers.
In 2003, the acquisition of J.S. Popper, Inc. added a line of insulation-piercing test clips and test leads for telecom test applications. The J.S. Popper insulation-piercing test clip is Bell standard, and called out in the designs of leading manufacturers of telecom test equipment such as Harris, Fluke and Tektronix.
Mueller purchased Crane Connectors in 2004, adding a broad line of board to board connectors, pin headers and sockets. Crane Connectors cross to full pc board connector brands such as Samtec, while offering flexibility and custom manufacturing capability.
Today, Mueller markets its three core product lines of board to board connectors, electric test clips and test leads/accessories through leading authorized distributors. The Company also sells direct to qualifying manufacturers. Mueller strives to live up to its distinguished heritage as a pioneer and leader; Mueller clips were on Admiral Byrd's arctic expeditions and its pin headers are circling the globe today in the International Space Station.
