## Summary description

Lapp RJ45 CAT.5e FM45 is a straight RJ45 wire connector in grey. Designed for CAT.5e structured cabling, it provides a standard 8P8C interface for Ethernet terminations. Suitable for wiring and patch panel connections, the connector supports typical CAT.5e uses such as 100BASE-TX networks and general data cabling installations.

## Long description

Lapp RJ45 CAT.5e FM45 straight, grey is a single-piece RJ45 wire connector designed for CAT.5e structured cabling. The connector provides a standard 8P8C interface for Ethernet terminations and is intended for use in typical CAT.5e installations such as 100BASE-TX networks, patch panels and point-to-point cable runs. Constructed for straightforward cable termination, this straight connector accommodates stranded and solid conductors commonly used in data cabling.
Advantages
The connector offers a compact, colour-neutral design that integrates with existing network hardware. It enables reliable electrical contact for CAT.5e performance levels and supports quick terminations without need for specialized tools beyond standard crimping or insertion implements. The grey housing provides visual consistency in installations and helps distinguish CAT.5e terminations from other categories in mixed-cable environments.
Suitable for
 100BASE-TX Ethernet horizontal and patch cabling
 Termination of CAT.5e twisted-pair cables in wall outlets and patch panels
 Field repairs and point-to-point network cable assembly
 Small office and residential structured cabling projects
Key specifications
 Cable category: CAT.5e
 Connector type: Straight RJ45, 8P8C
 Housing colour: Grey
 Conductor compatibility: Solid and stranded twisted-pair conductors
 Intended application: Ethernet data transmission up to CAT.5e performance
 Mounting/connection: Inline termination for patching and cable ends
How to use
Prepare the CAT.5e cable by stripping the outer jacket to expose the twisted pairs and untwist pairs only as much as required for reliable contact. Arrange the conductors according to the chosen wiring standard (T568A or T568B) and insert them fully into the connector until each conductor seats into its contact. Use an appropriate crimping or insertion tool designed for RJ45 terminations to secure the connection and ensure stable contact. Verify continuity and pair integrity with a cable tester after termination.
Usage recommendations
For consistent CAT.5e performance, keep untwist length minimal and avoid excessive bending or strain on the terminated end. Use cable testers to confirm wiring and signal integrity before deploying the cable in active network installations.
