Custom Faston Terminal Wire Harness Manufacturer

Yihetai manufactures custom Faston terminal wire harnesses for appliances, switches, motors, power supplies, lighting systems, control cabinets and automotive electronic equipment.

Faston terminal cable assemblies are widely used where quick connection, stable conductivity and easy installation are required. Compared with permanent soldering, Faston terminals allow faster assembly, easier maintenance and more flexible replacement during equipment production or repair.

We can customize wire length, wire gauge, terminal size, insulation sleeve, heat shrink tube, connector type, label and packaging according to your drawing, sample or application requirements.

What Makes Faston Terminal Wire Harnesses Different?

Faston terminal wire harnesses are different from many other terminal cable assemblies because they are designed for quick connection and disconnection. The terminal can be pushed onto a matching male tab, switch blade, relay terminal, thermostat terminal or equipment contact without soldering.

This makes Faston terminal harnesses especially useful in products that need fast assembly, easy repair, field maintenance or replaceable electrical modules.

Typical Faston terminal connections are found inside:

Home appliances
Heating elements
Motors and fans
Relays and switches
Thermostats
Power supplies
HVAC equipment
Vending machines
LED lighting modules
Control cabinets
Automotive auxiliary systems

For OEM manufacturers, a well-designed Faston terminal harness can reduce wiring complexity, improve assembly efficiency and make product maintenance more convenient.

Faston Terminal Sizes and Selection Guide

Faston terminals are available in different tab widths and structures. Choosing the right terminal depends on the mating component, current requirement, available space, wire gauge and operating environment.

Common Faston terminal sizes include 110, 187 and 250 series. These sizes are widely used in electrical equipment, appliances and industrial control systems.

Faston Series	Approx. Tab Width	Typical Applications
110 Series	2.8 mm	Compact switches, small control circuits, signal connections, small appliances
187 Series	4.8 mm	Appliance wiring, relays, thermostats, medium-load electrical modules
250 Series	6.3 mm	Power circuits, motors, heaters, HVAC equipment, control panels
Flag Faston Terminal	Customized by design	Narrow spaces where a straight terminal is difficult to install
Piggyback Faston Terminal	Customized by design	Shared connection points or branch wiring designs

If the application has limited installation space, a flag Faston terminal may be a better choice than a straight terminal. If two wires need to connect to the same electrical point, a piggyback Faston terminal can help simplify the wiring structure.

Yihetai can manufacture Faston terminal cable assemblies according to your terminal size, wire gauge, mating direction and installation requirements.

Custom Faston Terminal Harness Configurations

Yihetai can manufacture different Faston terminal wire harness configurations according to the electrical design of your product.

Configuration	Description	Common Use

Faston to ring terminal cable	One Faston end and one ring terminal end	Grounding, power connection, chassis connection
Faston to connector cable assembly	Faston terminal on one side, connector on the other	Control modules, sensors, LED drivers, equipment wiring
Faston to open-end wire	One Faston terminal with stripped or tinned wire end	Internal assembly, soldering or custom connection
Multi-branch Faston harness	Multiple Faston terminals in one harness	Control panels, appliances, power distribution
Piggyback Faston harness	One terminal allows another connection point	Shared circuits or branch connections
Flag Faston harness	Right-angle terminal structure	Limited-space installation

Each harness can be customized with different wire colors, labels, heat shrink tubing, protective sleeving, cable ties, terminal insulation and packaging methods.

Faston Terminal vs Ring Terminal vs Spade Terminal

Different terminal cable assemblies are selected for different installation methods. Faston terminals are mainly used for quick-connect and quick-disconnect applications. Ring terminals are used when a screw or bolt-fixed connection is required. Spade terminals are often selected when the connection needs to be installed under a screw but removed more easily than a ring terminal.

Yihetai can manufacture Faston, ring, spade, flag, piggyback and mixed-terminal wire harnesses according to your equipment design.

Terminal Type	Connection Method	Best For
Faston Terminal	Push-on quick disconnect	Switches, relays, thermostats, appliance modules
Ring Terminal	Screw or bolt fixed	Grounding, battery connection, chassis connection
Spade Terminal	Screw connection with open fork	Removable screw terminals, control panels
Flag Terminal	Right-angle quick connection	Compact installation space
Piggyback Terminal	Shared quick-connect point	Branch circuits or multiple connections

If you are not sure which terminal style is suitable for your product, Yihetai can review your drawing, sample or application requirement and help recommend a practical cable assembly solution.

Engineering Considerations for Faston Terminal Harness Design

A reliable Faston terminal harness is not only about choosing the correct terminal. Engineers also need to consider wire size, current load, terminal material, crimping quality, insulation protection and the environment where the product will be used.

When designing a Faston terminal cable assembly, the following points should be confirmed:

– Mating tab size
– Male or female terminal type
– Straight, flag or piggyback terminal structure
– Insulated or non-insulated terminal
– Wire gauge and conductor material
– Working voltage and current
– Operating temperature
– Vibration or movement during use
– Cable length and routing direction
– Need for heat shrink tubing or protective sleeve
– Labeling and polarity identification
– Testing standard before shipment

For higher current circuits, terminal material, plating, crimp height, wire gauge and contact stability should be carefully controlled. For compact equipment, the terminal angle and cable exit direction are also important to avoid stress on the wire or connector.
