With an endless variety of electrical connector plug (ปลั๊ก , which is the term in Thai) types and several crucial criteria to consider, choosing the right one can be downright tricky; however, selecting the right connector is the most reliable and efficient way to improve, modularize, or downsize a system so that it runs smoothly without needing frequent repairs.
List Your Requirements
The compound of signals has an impact on the connector type, pin out, and wiring. High-frequency signals, for instance, may require a coaxial connection, while low-level analog signals may require shielding.
Specific signal combinations can’t be involved in a particular connector. If it includes high voltage pins, you may have to consider clearance and creepage distances. If high current paths are included, you may have to make use of bigger wires and multiple pins.
Consider Your Current Rating and Operating Voltage
Current rating is the most vital when choosing electrical cable connectors. It measures in amps per circuit the amount of current that can flow through a mating terminal. The flow of current should be derated or adjusted based on the rate of circuits in a specific housing and the rise in temperature of the adjacent terminal.
Check for Space Constraints
The weight and size of electrical cable connectors and terminal connectors have reduced in correspondence to the reduction in space available for them; however, their ability to withstand an increase in unmating and mating frequency has increased considerably. So, depending on the situation that applies to your project and its design needs, you may have to look for further alternatives in electric connectors.
Verify the Recommended Operating Temperature Range
Most electric connectors are subjected to extreme conditions like shock and vibration. Electrical cable connectors and terminal connectors that are designed for hazardous environments and extreme conditions incorporate unique features that resist shocks and vibration and withstand extreme temperatures.
