Spade connectors can be used in various areas such as, machinery, electrical equipment, home appliances, computers, cars workshop and garages plus many more. These electrical connectors are often used by electricians, technicians, home users and hobbyists to disconnect electronic components from circuits.

Selecting the Correct Connector Size
When selecting the right terminal for your application, you should consider the following:

The wire size 'mm' (metric) or 'AWG' (American Wire Gauge) you are using

The tab size to which you will be connecting the ring terminal. The width of the receptacle must match the width of the tab it is mating with and vice versa. The width is usually shown as a series name in inches, the most common ones being 0.110 (2.8mm), 0.187 (4.8mm), 0.205 (5.2mm), 0.250 (6.3mm), 0.375 (9.5mm). The thickness of the tabs can also vary and are usually 0.51 or 0.81mm

How to Crimp a Receptacle Connector
Strip the end of the wire and cut it to the same length as the terminal. Insert the stripped end into the barrel making sure no bare wire is visible. The connector is then ready to be crimped on to the end of the wire. Pliers or a ratchet tool can be used but, for a better-quality crimp, it is better to use a ratchet crimping tool. A ratchet crimping tool is preferable as the handles will remain locked until a full crimp cycle is completed which will prevent partial crimps. Insert the barrel of the receptacle terminal into the appropriate crimping section (indicated by sizes marked on the tool). Squeeze the tool handles together until the ratchet releases. The crimped receptacle terminal is now ready for mating with a male tab terminal to form a secure electrical connection.
