Why Choose the Partex RR120/RA M12 Red Right-Angled Ring Terminal?
The Partex RR120/RA is a red pre-insulated right-angled ring crimp terminal designed for terminating copper conductors onto M12 threaded studs and bolted electrical connections. Featuring a right-angled terminal configuration, it provides a practical alternative to straight ring terminals where cable routing, connection orientation or installation space requires a different approach.
Designed for 0.5–1.5 mm² copper conductors (22–16 AWG), the RR120/RA combines a conductive copper terminal with high-quality red PVC insulation around the crimp barrel. The colour-coded insulation helps installers identify the appropriate conductor size range and supports consistent terminal selection during electrical assembly and maintenance.
The M12 closed-ring connection is designed to fit compatible 12 mm threaded studs, providing secure retention when installed beneath a correctly tightened fastening assembly. Supplied in a convenient pack of 100 terminals, the Partex RR120/RA is suitable for electrical contractors, panel builders, machinery manufacturers and industrial maintenance teams requiring right-angled cable terminations.

Secure Right-Angled M12 Connections for Electrical Wiring
Ring terminals are widely used to connect electrical conductors to threaded studs, terminal posts and bolted connection points. The Partex RR120/RA provides a right-angled M12 ring termination that allows the conductor to approach the fastening point in a different orientation from a conventional straight ring terminal. This can be particularly useful when wiring arrangements or equipment layouts make a straight cable entry less convenient.
The closed-ring design helps retain the terminal on the stud while the fastening assembly remains correctly installed. Unlike an open-ended fork terminal, a ring terminal generally requires the fastening nut to be removed before the terminal can be detached. This makes it suitable for connections where secure mechanical retention is a priority.
The RR120/RA is intended for 0.5–1.5 mm² copper conductors, with its red PVC insulation providing a convenient visual indication of the applicable wire size category. Using the correct terminal size and crimping profile is essential for producing a reliable electrical and mechanical connection.
For correct installation, the conductor should be stripped to the appropriate length, inserted fully into the crimp barrel and compressed using a suitable tool designed for red pre-insulated terminals. The completed crimp should be inspected for conductor retention and proper compression before the ring is secured to the compatible M12 connection.
The right-angled construction may also assist with cable management by allowing the wire to follow a more suitable route away from the connection point. The finished assembly should be checked for adequate cable clearance, suitable bend radius and compliance with the equipment manufacturer's installation requirements.
Typical Applications
- Termination of 0.5–1.5 mm² copper conductors onto M12 threaded studs.
- Electrical control panels requiring right-angled cable connections.
- Industrial machinery and equipment wiring.
- Bolted electrical connections with restricted cable routing space.
- Electrical equipment manufacturing and assembly.
- Industrial maintenance and replacement of existing ring terminals.
- Cable harness production requiring angled terminal arrangements.
- Commercial and industrial electrical installations.
