CIF Q4/2 2.4 ILME PCB mount interface 4+2 contacts for CQ04/2, 2.4mm board

Why Choose the Ilme CIF Q4/2 2.4 PCB Interface Adapter?

The Ilme CIF Q4/2 2.4 is a specialised PCB interface adapter for CQ 04/2 industrial connector inserts, designed to provide a direct cable-to-printed-circuit-board connection in machinery, automation and industrial electronics. It supports the CQ 04/2 contact arrangement of 4 main poles + PE with 2 auxiliary contacts and is suitable for printed circuit boards up to 2.4 mm thick.

The adapter accommodates both the higher-current main connections and lower-current auxiliary circuits used by CQ 04/2 inserts. The main circuit is rated at 30 A, 400–690 V with a 6 kV rated impulse withstand voltage, while the auxiliary circuit is rated at 7.5 A, 250 V with a 4 kV impulse withstand voltage, providing a compact interface for combined power and control applications.

Designed for solder mounting to the PCB, the CIF Q4/2 2.4 helps eliminate intermediate wiring between the connector and circuit board, reducing assembly time and the potential for wiring errors. Its robust construction, silver-plated contacts and -40 °C to +125 °C operating temperature range make it well suited to modular industrial equipment and demanding electronic assemblies.

Reliable Combined Power and Signal Connectivity to the PCB

The Ilme CIF Q4/2 2.4 enables CQ 04/2 connector systems to interface directly with a printed circuit board. For the main power contacts, compatible CQF 04/2 female inserts use CXFFA interface contacts and compatible CQM 04/2 male inserts use CXMFA interface contacts. The two auxiliary circuits use CDFA 6A28 female or CDMA 6A male interface contacts as appropriate for the selected insert.

By allowing these interface contacts to terminate directly at the PCB, the adapter reduces the need for intermediate point-to-point wiring and supports more repeatable production assembly. This combination of higher-current power poles and auxiliary contacts makes the CIF Q4/2 2.4 particularly useful where power and control or signal circuits need to pass through a single compact industrial connector interface.

Typical Applications

• Industrial control and automation PCBs.
• Combined power and signal interfaces.
• Motor control and drive electronics.
• Modular machinery and production equipment.
• Replaceable industrial electronic assemblies.
• Cable-to-board connections using Ilme CQ 04/2 connectors.
