Why Choose the Partex RS37N/RA Red Narrow Spade Terminal?
The Partex RS37N/RA is a red insulated narrow fork (spade) crimp terminal designed for connecting electrical conductors to compatible M3.5 screw terminals. Featuring a compact, narrow fork configuration, this terminal is particularly useful where connection space is limited or where adjacent terminal positions require a slimmer fixing profile.
The open-ended fork design allows the terminal to be positioned beneath a suitable screw head without completely removing the fixing. This can simplify wiring assembly, servicing and replacement work in electrical control panels, terminal assemblies and industrial equipment. Its red insulated crimp barrel provides visual identification and helps cover the conductor termination area.
Supplied in a convenient pack of 100 terminals, the Partex RS37N/RA is suitable for electricians, panel builders, equipment manufacturers and maintenance engineers requiring practical, screw-fixed electrical connections. The combination of an M3.5 fixing size, narrow fork design and crimp termination makes it a useful addition to professional electrical wiring supplies.
Key Advantages
- Narrow fork design is useful for compact terminal arrangements and restricted installation spaces.
- M3.5 screw compatibility for suitable electrical terminal connections.

Convenient Narrow Fork Connections for Electrical Wiring
Insulated fork terminals are widely used in electrical installations where a conductor must be attached to a screw-fixed connection point. The Partex RS37N/RA features an open-ended fork that can be positioned around a compatible M3.5 fixing screw. Compared with a closed-ring terminal, this arrangement can make disconnection and maintenance more convenient because the screw may only need to be loosened rather than completely removed.
The narrow fork profile is particularly useful where terminal positions are closely spaced or the available fixing area is restricted. However, the terminal must still fit correctly beneath the screw head or clamping plate, and the equipment's terminal design must be suitable for fork-style connections. The selected fixing should retain the fork securely when tightened to the specified torque.
The RS37N/RA uses a red insulated crimp barrel for attachment to a compatible electrical conductor. Installation involves stripping the conductor to the appropriate length, inserting it into the barrel and applying a correctly matched insulated-terminal crimping tool. A properly formed crimp helps provide mechanical retention and electrical continuity without soldering.
Before installation, users should verify the conductor cross-sectional area, insulation diameter, fork dimensions, terminal ratings and suitability for the electrical equipment. The red insulation colour is useful for identification, but the correct conductor range and crimping requirements should be established from the manufacturer's technical information rather than colour alone.
Typical Applications
- Electrical control panel assembly and terminal wiring.
- Connections to compatible M3.5 screw terminals.
- Compact electrical equipment and terminal arrangements.
- Industrial machinery and automation system wiring.
- Electrical equipment manufacturing and cable harness assembly.
- Maintenance and replacement of insulated fork terminal connections.
