Why Choose the Ilme CRCKT Fixing Frame?
The Ilme CRCKT, also identified as CR CKT, is an insulating fixing frame for complete size 21.21 free connector couplings. It provides a secure mounting solution for compatible Ilme 21.21 connector assemblies, allowing interconnected hoods to be supported independently of a conventional panel-mounted connector housing.
Designed for flexible industrial installation, the CRCKT can be screw-mounted directly to a backplate or wall or snapped onto a standard DIN EN 60715 35 × 7.5 mm rail. DIN-rail mounting is possible across either the short or long side of the rail, giving panel builders greater freedom when arranging connector interfaces inside machinery and control cabinets.
The frame is manufactured from black polycarbonate (PC), RAL 9005, with a UL 94 V-0 flame-retardant classification. Its base incorporates two flexible lyre-shaped retaining arms that hold the complete 21.21 connector coupling, while two black cable ties are supplied for additional retention of the connector hoods.
Key Advantages
- Purpose-designed for complete Ilme size 21.21 free connector couplings.
- Supports both wall/backplate and DIN-rail mounting.
- Snaps onto DIN EN 60715 35 × 7.5 mm rail.
- Allows DIN-rail installation on either the rail's short or long side.
- Insulating polycarbonate construction avoids the need for a metallic mounting frame.
- Lyre-shaped elastic arms provide releasable retention of the connector coupling.
- Supplied with two black cable ties for additional securing of the connector hoods.
- Allows convenient inspection and replacement of mounted connector assemblies.

Flexible Wall and DIN-Rail Mounting for 21.21 Connectors
The CRCKT extends Ilme's connector support solutions by allowing a complete free 21.21 connector coupling to be mounted directly within machinery or control equipment. Its two elastic lyre-shaped arms embrace the connector hoods and allow the assembled coupling to be inserted and removed without permanently fixing the connector itself to the mounting surface.
For permanent positioning, the base can be fixed to a backplate using screws, which are not supplied, or snapped onto a 35 × 7.5 mm DIN rail. Holes at the ends of the retaining arms accommodate the two supplied cable ties, providing additional security where vibration or mechanical movement could otherwise affect the mounted connector assembly.
Typical Applications
- Mounting complete Ilme size 21.21 connector couplings.
- Industrial control cabinets and panels.
- DIN-rail mounted connector interfaces.
- Machinery wiring and cable-management systems.
- Factory automation equipment.
- Machine building and OEM installations.
- Connector assemblies exposed to vibration or mechanical movement.
- Installations requiring convenient connector inspection or replacement.
