120-M-227-SMD/02 - 

The solder retention devices (SMT anchors) provide an exceptionally high retention force for the terminal block to the PCB. The most significant benefit of this design is the protection it provides to the solder joints against stresses encountered in field-installations. This is the strongest SMT retention method in the industry. The anchoring element constitutes a Universal SMT retention method (can be licensed for other applications). It eliminates completely CTE mismatch (Coefficient of thermal expansion) and provide total coplanarity (contains position adapting pin). Removable thermo resistant pick caps are supplied when packed in tape and reel. This allows automated pick & place applications.
