The Ilme CTSEF24L, manufacturer reference CTSEF 24 L, is a female 24-pole plus protective earth multipole connector insert with an incorporated terminal block and left-side mounting. Part of the Ilme CTSE series, it combines a compact wedge-style arrangement with spring terminal technology for dependable industrial machinery, automation and control connections.
Rated at 16 A and 500 V, the CTSEF24L has a rated impulse withstand voltage of 6 kV and pollution degree 3. Its spring terminals accommodate conductors from 0.14–2.5 mm² (26–14 AWG), providing secure conductor clamping without the routine tightening associated with conventional screw terminals.
Designed for the Ilme size 104.27 format, the CTSEF24L incorporates turned, silver-plated female contacts and a durable polycarbonate insulating body. It can be installed from either the front or rear of a suitable enclosure and is designed to mate with compatible Ilme CNE, CCE, CCS, CSE and CSH inserts, providing flexibility for industrial connector system design.

Reliable Left-Side Spring-Terminal Connectivity
The Ilme CTSE series combines an incorporated terminal block with spring-pressure conductor termination, providing an efficient alternative to conventional screw-terminal wiring. The CTSEF24L accepts conductors from 0.14–2.5 mm² and maintains consistent terminal pressure, supporting reliable electrical connections in machinery and automation installations.
Its left-side mounting configuration and ability to be fitted from either the front or rear of the enclosure provide useful flexibility when planning wiring access. When installed in a compatible Ilme enclosure and paired with a suitable mating insert, the CTSEF24L creates a robust detachable interface for power, control and machine wiring.
