3M and Digi-Key Introduce the Extended Line of Compact Mini-Clamp Connectors for Demanding Applications

The 3M Mini-Clamp Connector doesn't require any special tooling for wire preparation or termination. All you need is a pair of pliers. It accepts 20-26 AWG wire and wire diameters ranging from 0.8 to 2.0 mm. The semi-transparent cover allows the IDC wire termination to be inspected for reduced maintenance work. Its compact design also saves board space. Get the 3M Mini-Clamp Connector and take advantage of proven IDC technology from 3M today. It really is that easy!


3M Mini-Clamp Connectors

3M Mini-Clamp Connectors are designed to provide connection reliability and cost performance in I/O applications commonly found in a wide range of sensor control systems, including factory automation and industrial controls. 3M Mini-Clamp products use 3M’s advantageous IDC technology which does not require any special tooling or pre-treatment of cables, and can be terminated using a standard pair of pliers. Benefits of the Mini-Clamp products include a simple installation process that does not create material debris or waste; a labor saving IDC termination process relative to traditional interconnect alternatives; ease of assembly for system building; and a design that provides for consistent quality and reliability. Features include a semi-transparent cover, color-coded covers to provide for the proper wire usage, and wire alignment and retention built into the cover. These features allow proper wire termination along with latches and polarization to allow for proper mating of the connectors.

3M Mini-Clamp Connectors are part of a serial field bus system solution that is designed to reduce the space of sensor wires in factory automation machines when compared to parallel wiring approaches. The total field installation costs (assembly and wiring) can be reduced when the 3M Mini-Clamp products are used – especially in combination with the 3M Link Connector offering. The termination process of traditional connectors (crimp connectors or terminal blocks) is complicated, labor intensive and typically creates debris and waste which may be an issue in clean room environments found in semiconductor, LCD and medical applications. The 3M Mini-Clamp connector will provide for an easier and debris-free wire termination process.
