Description of system
IDC housings
- Direct and indirect connectors with IDC termination in accordance with the RAST 2.5 standard specification for domestic appliances
- Closed cable entries ensure long air and creepage distances
- Trimming polarizing pegs to individual requirements produces a large number of clearly defined connector combinations
- With direct edge versions, polarizing and locking feature for PCB
Pin connectors
- In vertical and horizontal versions facilitate 90° and 180° cable angles
- SMT version for vertical PC board assembly
Pin connector panel mount
- Pin connector with IDC termination for entry through back panel
- Lockable in metal thickness 0.8 ± 0.1 mm
