CDSF27N Ilme Female insert 27 pole and earth 10 amp spring
ILME CDSF27N is a CDS series 27-pole + PE female spring-terminal insert for poles 28–54 of a size 77.62 assembly, rated at 10 A 400 V with a 0.14–2.5 mm² conductor range.
Why Choose the ILME CDSF27N 27-Pole + PE Female Insert?
The ILME CDSF27N is a 27-pole + PE female connector insert designed as the second section of a high-density CDS series spring-terminal connector assembly. ILME identifies this N version with pole numbering 28–54, allowing it to be combined with the corresponding first 27-pole section to create a complete 54-pole + PE connection within a size 77.62 assembly.
The CDSF27N uses spring terminal connections, allowing conductors to be terminated directly without separate removable crimp contacts. It accepts conductor cross-sections from 0.14–2.5 mm², equivalent to AWG 26–14, and incorporates precision-turned silver-plated contacts for dependable electrical performance in industrial machinery, automation and control applications.
Rated at 10 A and 400 V, the CDSF27N provides a 6 kV rated impulse withstand voltage at pollution degree 3 and a UL/CSA rated voltage of 600 V. Its polycarbonate construction, wide operating temperature range and spring termination system make it a robust choice for high-density industrial connector assemblies requiring reliable and serviceable wiring.

High-Density Spring Terminal Connections for Industrial Machinery
The ILME CDSF27N is specifically configured as the 28–54 pole section of a larger CDS connector arrangement. When used with the corresponding first 27-pole section, the size 77.62 assembly provides 54 electrical poles plus protective earth, enabling a large number of control, signal and auxiliary circuits to be consolidated into one detachable industrial connector system.
Its spring terminals accept conductors from 0.14–2.5 mm² and require a stripping length of 9–11 mm. The integral turned silver-plated contacts remove the need to select and install individual crimp contacts, helping simplify connector assembly while providing a secure and serviceable termination system for industrial machinery and automation wiring.
Typical Applications
- High-density industrial machinery connections.
- Factory automation and production equipment.
- PLC and industrial control systems.
- Control panels and electrical cabinets.
- Robotics and automated handling equipment.
- 54-pole multipole control and auxiliary cable assemblies.
