👉 Pins fluid, often referred to as PINs (Pulse In/Negative Pulse), is a critical component in electronic systems, particularly in automotive and industrial applications. It represents the electrical signal that indicates the presence or absence of a voltage at a specific pin on a circuit board. The "Pulse In" phase occurs when the power supply is active, and the pin reads a high voltage, while the "Negative Pulse" phase happens when the power is off, and the pin reads a low voltage. This binary-like signal (high/low) allows electronic devices to detect the power status and make decisions based on it, such as turning on or off relays, sensors, or other control circuits. The precision and reliability of PINs are crucial for ensuring the proper functioning of complex systems, making them an essential part of modern electronics.
