Challenges & Opportunities
Small connector, big impact
The very powerful and robust MP11 connectors in the Fischer MiniMax™ Series are used in the 6-axis force sensors. What makes them special is that, during cable assembly, the individual strands are encapsulated several times and the cable sheath is overmolded using special molding technologies to prevent resistance changes from occurring during vibrations and cable movements. The cable from the sensor to the amplifier must demonstrate stable resistance behavior under thermal and mechanical stress, which is usually achieved through a special drag chain-compatible cable design and supported by the molding process on the connector. This combination results in very high vibration resistance.
Connecting and disconnecting the interconnect cable is equally safe and robust with this connectivity system. This saves service technicians a considerable amount of time when assembling, installing, servicing or calibrating the system. Moreover, the MiniMax connectors compel on account of their low weight, very compact dimensions, and resistance to liquids up to IP68.
“In the past, we’d tested various connectors from different manufacturers, but we’d always came up against the same problems: The connectors were either prone to vibration, not waterproof, too heavy or complicated to assemble. All in all, they didn’t meet our requirements nor those of the application. When we came across the Fischer MiniMax(™ Series connectors, we’d found our solution. The MiniMax connectors are compelling, particularly due to their low weight, very compact dimensions and resistance to liquids in compliance with IP68.”Dr. Holger Kabelitz Managing Director of ME-Meßsysteme GmbH
Since ME-Meßsysteme also has even smaller multiple sensors in its portfolio, with the K3R 3-axis force-torque sensor and the K3D 3-axis force sensor, the company was also looking for a solution with the same requirements here. The K3R and K3D measure forces on the X, Y and Z axes. For this, 12 connections are required, namely four per strain gauge. Since this application is even smaller than the K6D, a special solution was needed here too. Again, Fischer Connectors was able to help with its MiniMax connectors. For such small and special applications, the MiniMax in size 06 with 12 contacts and a reduced diameter offers the same benefits as in the K6D family for all three measuring channels. Even the smallest connectors in the Fischer Minimax™ Series enable extremely robust signal transmission. Not even machine vibrations influence the transmission resistances or the resultant signal stability.
