Benefits & Use Cases

• High Signal Density: Accommodates many lines in a compact connector shell, saving panel space and reducing connector count.
• Modular Integration: Compatible with ILME C‑Type connector housings (hoods, bases) for creating sealed, rugged connector assemblies.
• Industrial Reliability: Crimp terminators ensure low resistance, dependable contact under vibration and industrial conditions.
• Scalable Solutions: Useful in automation, control systems, machine tool connections, robotics, and other applications requiring many signal lines in one interface.
• Serviceability: Since contacts are crimped (not soldered), maintenance or replacement is more manageable in the field.

Ordering & Compatibility Notes

• Insert Only: CDDF‑72 is only the insert; it does not include housing (hood or base) or the crimp contacts.
• To assemble a complete connector system, you will also need:
    • A matching hood / cable-side housing compatible with 77.27 shell size
    • A base / bulkhead housing for the panel side, if needed
    • The correct crimp contact pins (socket type) that match the part series and wire gauge
• When mounted in a hood / base, proper gasket sealing, alignment, and torque are essential to achieve the rated IP protection.
• Confirm that the mating levers / mechanical features (pegs, latch positions) match between your housings and this insert.
• Be sure to verify that your application’s voltage, current, and environmental ratings align with the specs above.
• Some suppliers list variants (e.g. “CDDF‑72N” for double‑module or extended variants) — ensure you order the correct version for your connector layout.
