Why Choose the ILME CQF21 Female Connector Insert?

The ILME CQF21 is a compact, high-density female multipole connector insert designed for reliable signal and control connections in industrial machinery, automation equipment and electrical systems. Part of the ILME CQ series, it provides 21 poles within the compact size 21.21 format and uses replaceable crimp contacts for secure conductor termination.

The CQF21 is designed for use with compatible ILME rectangular multipole connector hoods and housings. Its crimp termination system accepts separately ordered female contacts, allowing the appropriate contact to be selected for conductor cross-sections from 0.08–0.52 mm². This makes the insert particularly suitable for applications requiring numerous low-current circuits within a small connector footprint.

Rated at up to 6.5 A with a nominal rated voltage of 50 V AC, the CQF21 provides a space-efficient solution for industrial signal, instrumentation and control wiring. Its thermoplastic insulating body, broad operating temperature range and robust construction support dependable service in demanding industrial environments.

Compact Crimp Connections for Industrial Control Systems

Crimp connector inserts such as the ILME CQF21 provide reliable conductor termination by mechanically securing each wire within a dedicated contact. Correctly executed crimp connections provide consistent electrical characteristics and resistance to vibration while also allowing contacts to be individually installed or serviced.

The CQF21 combines 21 electrical contacts within the compact size 21.21 format. Compatible female crimp contacts are selected according to the conductor cross-section and ordered separately, allowing the connector assembly to be configured for the specific signal and control wiring requirements of the installation.

Typical Applications

  • Industrial machinery and machine building.
  • Factory automation and production equipment.
  • PLC and electrical control systems.
  • Instrumentation and low-voltage signal circuits.
  • Robotics and automated handling systems.
  • High-density industrial control interconnections.
