RAST connectors are standardized wire-to-board interconnect systems based on IDC (insulation displacement contact) technology, enabling fast termination without stripping or soldering. Variants such as RAST 2.5 and RAST 5.0 indicate different contact pitches, supporting flexible design requirements and efficient assembly. Designed with keying and locking features, RAST connectors help prevent mismating and ensure reliable connections. Supporting both signal and power transmission, they are widely used in automotive, industrial, and appliance applications.
