1.27mm SMC Connector Socket

Short Description:

Limited space and high-performance demands are characteristics of many modern electronic systems, all of which the connectors must accommodate. There is a corresponding demand for compact, secure, and reliable connectors, with high signal integrity and a relatively high current‐carrying capacity. The comprehensive SMC range helps meet these requirements. The high‐performance SMT connectors come in a number of different designs, heights, and contact densities in a 1.27 mm grid.

Technical information

Limited space and high-performance demands are characteristics of many modern electronic systems, all of which the connectors must accommodate. There is a corresponding demand for compact, secure, and reliable connectors, with high signal integrity and a relatively high current‐carrying capacity. The comprehensive SMC range helps meet these requirements. The high‐performance SMT connectors come in a number of different designs, heights, and contact densities in a 1.27 mm grid.

The basic design criteria for the SMC series include Double spring terminals ensure first-class contact characteristics and maximum contact reliability, a high‐temperature resistant insulator with polarization and insertion chamfers, and a very high mating reliability.

The perfect contact design exhibits a virtually continuous impedance curve and enables secure data transmission rates of up to 3 Gbit/s (differential) if the system is suitably designed.

Advantge

● High reliable contact design

Extremely reliable double contact female terminal

90° torsion spring terminal

The rolling surface has a uniform texture to ensure that the terminals are firmly inserted

Large contact area between male and female terminals

Extremely low bending surface roughness, minimizing surface wear

Low contact  resistance

● Polarization / Mating Face

image8.jpeg

Fool-proof design of the mating surface to prevent incorrect insertion and connection errors

The chamfer around the plastic ensures a large guide tolerance

Unique single hole chamfer design facilitates precise insert

● Robust Solder Clips

Excellent holding power on the circuit board

The fixed piece can absorb mechanical stress and can withstand high impact and vibration loads

SMT connectors are firm and reliable, ensuring sufficient shear and tear resistance (for example: shear force: minimum 1000 N; tear resistance: minimum 100 N)

● Friction Distance

image11.jpeg

Larger friction distance provides contact reliability and compensates for tolerances between different heights

● Positioning Column

Different geometries of positioning posts ensure precise positioning on the circuit board

To achieve the best compensation for PCB holes for positive and negative tolerances

Air-and creepage distance   contact - contact min. 0.4 mm
Operating voltage IEC 60664 The permissible operating voltages depend on the customer application and on the applicable or specified safety requirements. Insulation coordination according to IEC 60664‐1 has to be regarded for the complete electrical device. Therefore, the maxi‐mum creepage and clearance distances of the mated connectors are specified for consideration as a part of the whole current path. In practice, reductions in creepage or clearance distances may occur due to the conductive pattern of the printed board or the wiring used, and have to be taken into account separately. As a result, the creepage and clearance distances for the application may be reduced compared to those of the connector.

High Frequency Characteristics

● High-speed Data Transmission

SMC connectors can be used as solution for unshielded high-speed applications.

The practically continuous impedance profile allows for secure data transmission rates of up to 3 Gbit/s (differential) if the system is suitably designed.
