What is the difference between keyed and keyless rj45 jacks?

Keyed RJ45 jacks have a physical mechanism that ensures the connector can only be inserted in one orientation, providing a secure and reliable connection, often used in environments where accidental disconnection is a concern. Keyless RJ45 jacks, on the other hand, allow for insertion in multiple orientations, making them more versatile but potentially less secure. The keyed design is beneficial for applications requiring strict adherence to specific wiring configurations, while keyless jacks are more common in standard networking applications.
