Why Choose the Partex PXP35 Copper Flat Pin Connector?
The Partex PXP35 is a high-quality copper flat pin connector designed for terminating compatible 35 mm² copper conductors into suitable electrical terminals. Supplied in a convenient pack of 50 connectors, it provides a practical cable termination solution for electrical contractors, industrial panel builders, maintenance engineers and equipment manufacturers requiring reliable crimped electrical connections.
Part of the Partex PXP copper flat pin connector range, the PXP35 combines a conductor crimp barrel with a flat contact pin. The prepared copper conductor is inserted into the barrel and secured using a correctly matched crimping tool and die. When properly installed, this creates a permanent mechanical and electrical connection between the conductor and connector. The flat pin section can then be inserted into a compatible electrical terminal or clamping arrangement.
The Partex PXP35 35 mm² copper flat pin terminal is particularly useful for industrial electrical control panels, power distribution assemblies, machinery and specialist equipment wiring where a flat pin connection is specified. Its copper construction provides good electrical conductivity, while the crimped termination helps retain the conductor securely. The pack of 50 is well suited to panel production, repeat installation work and maintenance stockholding.

Reliable 35 mm² Copper Cable Terminations for Electrical Equipment
Copper flat pin connectors provide a practical method of terminating electrical conductors where the receiving equipment uses a compatible clamping terminal. The Partex PXP35 is designed for 35 mm² copper cable, combining a crimped conductor connection with a flat contact pin that interfaces with an appropriately designed electrical terminal.
The connector's crimp barrel receives the prepared conductor. During installation, a suitable crimping tool compresses the barrel around the copper strands using the correct die profile and compression method. When the connector, conductor and tooling are properly matched, this creates mechanical conductor retention and establishes electrical contact.
The flat pin section provides a defined contact surface for the receiving terminal. This can be useful where the terminal is designed to clamp onto a flat pin rather than directly onto a stranded conductor. However, the connector must be compatible with the receiving terminal's permitted contact dimensions and connection arrangement.
Correct crimping is particularly important for larger conductors such as 35 mm². Incorrect die selection, incomplete conductor insertion or insufficient compression may compromise the mechanical or electrical performance of the connection. Installers should follow the manufacturer's recommended conductor preparation, tooling and crimping procedures.
The completed connection must also be installed in accordance with the equipment manufacturer's instructions. The receiving terminal's conductor capacity, permitted connection types, tightening torque and electrical rating should all be checked. The finished cable should be routed and supported to avoid excessive stress on the connector.
Choosing the Correct 35 mm² Copper Flat Pin Connector
When selecting a flat pin connector, the first consideration is the conductor cross-sectional area. The Partex PXP35 is specified for 35 mm² copper conductors, making it a suitable option for consideration where this conductor size is used and the receiving electrical terminal accepts the corresponding flat pin contact.
Different flat pin connectors are available for different cable sizes. For example, the Partex PXP25 is intended for 25 mm² conductors, while the PXP35 is intended for 35 mm² conductors. Selecting the correct connector helps ensure that the conductor fits the crimp barrel and can be compressed using the appropriate tooling.
Conductor size alone does not establish compatibility with the receiving terminal. The flat pin width, thickness and insertion length must also be appropriate for the terminal's opening and clamping mechanism. These dimensions should be checked against the manufacturer's technical information rather than assumed from the nominal conductor size.
The conductor material and construction must also be considered. The PXP35 is a copper connector intended for compatible copper conductors. Aluminium conductors and mixed-metal connections require appropriately specified components and installation procedures.
Finally, the complete electrical connection must be suitable for the expected load and operating environment. The current-carrying capacity of a 35 mm² conductor does not automatically establish the rating of the connector and receiving terminal assembly.
Flat Pin Connectors vs Ring Terminals and Bootlace Ferrules
The Partex PXP35 copper flat pin connector is intended for a different connection arrangement from a conventional ring terminal. A ring terminal features a circular fixing hole and is secured using a stud or bolt. A flat pin connector instead provides a flat contact section designed for insertion into a compatible electrical terminal.
Flat pin connectors are useful where equipment manufacturers specify a flat contact interface. They allow the conductor to be crimped into the connector before the flat pin is positioned in the receiving terminal, providing a defined connection surface.
Bootlace ferrules are another common method of terminating stranded electrical conductors. A ferrule typically forms a tubular end around the conductor strands for insertion into a compatible clamping terminal. A flat pin connector, by comparison, provides a distinct flat contact shape. The two should not be considered interchangeable unless the equipment manufacturer explicitly permits both connection types.
Choosing between a flat pin connector, ring terminal, fork terminal or bootlace ferrule depends on the design of the receiving electrical equipment. The Partex PXP35 should be selected where a compatible 35 mm² copper conductor and an appropriately sized flat pin connection are required.
Installation Guidance for the Partex PXP35
Before installation, confirm that the cable is a compatible 35 mm² copper conductor and that the receiving electrical terminal is designed to accept the PXP35 flat pin connector. Check the terminal's contact dimensions, clamping arrangement and electrical rating.
The conductor should be stripped to the correct length using a suitable cable preparation tool. Care must be taken to avoid damaging or removing conductor strands. The stripped conductor should then be inserted fully into the connector's crimp barrel.
A compatible crimping tool and die should be used in accordance with the manufacturer's recommendations. The correct compression profile and crimp position are essential for producing a secure termination. After crimping, inspect the connector for complete conductor insertion, suitable compression and visible damage.
The flat pin should then be inserted into the receiving terminal as specified by the equipment manufacturer. Where a screw or bolt-operated clamp is used, the fixing should be tightened to the manufacturer's recommended torque rather than an assumed value.
Where the connector or crimped barrel requires electrical insulation, suitable insulating sleeving, heat-shrink tubing or enclosure protection should be provided. The finished cable should be routed and supported to minimise mechanical loading on the connection. Installation and testing should follow applicable electrical regulations and equipment instructions.
