## Summary description

Shielded RJ45 network connector Hirose TM21 in grey, designed for Cat.6 installations. Supplied as a 3-piece modular plug (housing, insert, shield) in a pack of 100 (H7641.12-100). Suitable for industrial and commercial cabling where STP performance and reliable terminations are required. Facilitates secure, low-interference Ethernet connections and faster assembly for bulk installations.

## Long description

The RJ45-Hirose STP TM21 grey network connector is a shielded modular plug designed for Cat.6 installations. Supplied as a three-piece assembly — housing, insert and shield — this connector supports twisted-pair shielded cabling and is intended for industrial and commercial network installations where reduced electromagnetic interference and reliable terminations are required. The grey finish allows easy visual identification while the modular design speeds up bulk assembly and maintenance workflows.
Advantages
This STP TM21 connector provides consistent Cat.6 performance with reduced crosstalk and improved immunity to outside noise thanks to its metal shielding. The three-piece construction simplifies cable preparation and termination, enabling faster assembly for high-volume projects and easier inspection of individual components. Durable contacts and a secure strain-relief mechanism ensure stable connections in environments that demand mechanical reliability.
Suitable for
Cat.6 shielded Ethernet cabling in office and data center environments
Industrial and manufacturing network runs where EMI suppression is important
Bulk terminations and contractor installations requiring fast assembly
Retrofit or new installations that need reliable STP connectors
Key specifications
Connector type: Shielded RJ45 modular plug (3-piece: housing, insert, shield)
Cabling category: Cat.6 (support for 250 MHz bandwidth)
Shielding: Full metal shield for reduced electromagnetic interference
Color: Grey housing for easy identification
Contact system: Gold-plated contact surfaces for reliable signal transmission
Application: Suitable for stranded and solid shielded twisted-pair cables per Cat.6 guidelines
How to use
Prepare the shielded Cat.6 cable by removing the outer jacket to expose the foil and drain wire, then fold back the foil and trim the drain wire as appropriate for the insert design. Insert conductors into the modular insert following the correct wiring pattern and verify seating. Assemble the housing over the insert, engage the shield, and crimp or terminate according to standard practices and tool recommendations for the specific Hirose TM21 series connector. Verify continuity and shield integrity with appropriate network testers before deployment.
Usage recommendations
Use compatible crimping or termination tools designed for three-piece STP modular plugs to ensure consistent terminations. Maintain cable twist as close to the termination point as possible and secure strain relief to prevent mechanical stress on contacts. Test each terminated link for pair continuity, attenuation and shield continuity to confirm Cat.6 performance and EMI protection before putting links into service.
