The PA125-E is a spring-loaded test probe (also known as a pogo pin) designed for testing printed circuit boards (PCBs) and other electronic components. 

Specifications 

• Model series: P125, PA125
• Head/Tip style: E-type, which is often described as a conical or spearhead tip, suitable for contacting solder joints and pads.
• Overall length: 33.35 mm.
• Probe tube diameter: 2.02 mm.
• Probe head diameter: 2.5 mm.
• Minimum test spacing: 3.18 mm.
• Construction: Gold-plated phosphor brass for durability and corrosion resistance.

The PA125-E and similar spring test probes are widely used in the electronics manufacturing and testing industry for quality control. Its specific e-type tip design makes it particularly suitable for making reliable contact with flat solder pads and solder joints on a PCB.

The probes are used for several types of PCB tests, including:

• In-Circuit Testing (ICT): Checking for electrical connectivity and component values on a populated circuit board.
• Flying Probe Testing (FPT): An automated, fixtureless testing method where the probes "fly" between test points.
• Open and short-circuit tests: Verifying the integrity of the circuit paths.

• Through-hole components
• Terminals
• Wire wraps
• Other conductive points on a circuit board
