Gold plated Spring Test Probe PA50-J1 Pogo Pin

Test Pin Test Tool 16.35mm Dia0.68mm Gold Needle Tip

The PA50-J1 is a spring-loaded test probe, also known as a "pogo pin," used for creating reliable temporary connections during the testing of electronic components and printed circuit boards (PCBs). 

• Head shape: Round, designed for soft contact to prevent damage to sensitive components and PCB pads.
• Full stroke: The maximum distance the plunger can travel is 2.6 mm.
• Spring pressure: Pushes the plunger with about 75 grams of force, which ensures a solid electrical connection.
• Current rating: Can handle a maximum rated current of 3A.
• Resistance: Has a low contact resistance of approximately 50 mΩ.
• Materials:
  • Plunger: Made from heat-treated beryllium copper.
  • Barrel: Constructed from gold-plated phosphor bronze for excellent conductivity and corrosion resistance.
  • Spring: Made from music wire and is also gold-plated.
• Physical dimensions:
  • Probe tube diameter: 0.68 mm.
  • Probe rod diameter: 0.48 mm.
  • Probe length: 16.35 mm.

• Testing PCBs: Used to make contact with test points, pads, and "gold fingers" (edge connectors) to check for electrical continuity or other faults.
• In-circuit testing (ICT): Often integrated into custom test fixtures to program or check assembled PCBs on a production line.
• Component verification: Used to test individual electronic components.
• Prototyping and DIY projects: Provides a flexible and reusable solution for making temporary electrical connections.
