Introduction RADIALL has designed a complete range of microminiature coaxial connectors, dedicated to Surface Technology (SMT). Better than a simple SMT version of standard connector, MMS and MMT series were the first coaxial designed for SMT applications. Due to its optimized design, MMS and MMT range benefit from the following advantages: • esign adapted to automatic placement D The assymetric footprint of the MMS and MMT connectors allows video micro-positionning using the shadow to analyse its placement. MMS and MMT connectors stand on three pliable legs. This design guarantees the receptacle...

Our Most Important Connection is with You.™ Receptacle packaging ACCORDING TO IEC 286-3 STANDARD MATERIALS Reel: polyester Carrier tape: antistatic PETG (polyester) Cover tape: polyester PRECAUTION FOR USE Automated pick and place machines use standard tooling to peel the antistatic film off. Sometimes the "a" dimension of this tool is shorter than the overall "b" width between the two legs of the receptacle. There is thus a risk for the two legs being deformed while they pass through the tool during the suction operation. The user must then widen the "a" dimension of the peeling tool. Go online...
