Applications

• PCB QA Jigs: Build custom "bed of nails" fixtures for factory-level batch testing.
• Programming Adapters: Create temporary contact headers for flashing ESP32, STM32, and Arduino bare boards.
• Through-Hole Probing: The conical head is perfect for centering inside through-hole vias and plated pads.
• Battery Contacts: Use as highly reliable spring-loaded terminals in custom 3D printed enclosures.

Unlock New Capabilities

• Past Projects: If you've been manually soldering jumper wires to UART pads or holding header pins at awkward angles to flash code, you know the frustration of a slipped connection.
• The Upgrade: The P75-T2 unlocks the ability to build drop-in flashing jigs. Just press your board down, flash in seconds, and remove it pristine.
• Effort Level (Intermediate): Requires basic CAD/3D printing knowledge or precise perfboard drilling to align the pins with your target board's pads.

Package Includes:

• 1 x P75-T2 Spring Loaded Pogo Pin Test Probe for PCB Jigs

Frequently Asked Questions (FAQ)

• What is the head shape of the P75-T2?
  It features a conical (tapered) head, ideal for piercing flux residue or resting perfectly inside through-hole vias.
• What is the diameter of the P75-T2 conical head?
  The head diameter is exactly 1.3mm.
• What is the overall length of the pin?
  The total length of the P75-T2 is 16.54mm uncompressed.
• What pitch spacing is this pin designed for?
  It is designed to easily fit standard 2.54mm (0.1 inch) PCB grid spacing.
• Can I solder my wires directly to the P75-T2?
  It is highly discouraged. Soldering directly to the barrel can damage the internal spring. Use an R75 receptacle instead.
• Do I need a receptacle for this pin?
  While you can technically friction-fit them into precise holes, using a P75 series receptacle is standard practice for wiring and easy replacement.
• What is the barrel diameter?
  The main barrel diameter is 1.02mm.
• What is the maximum current rating?
  Standard P75 series pins are rated for approximately 3 Amps.
• Is the P75-T2 gold-plated?
  Yes, the body and plunger are gold-plated to ensure ultra-low contact resistance and prevent oxidation.
• Will this pin pierce through PCB oxidation?
  Yes, the sharp conical tip is specifically designed to bite through mild oxidation and flux residue to make electrical contact.
• How do I replace a broken P75-T2 in my jig?
  If you used a receptacle, simply pull the broken pin out with pliers and slide a new one in. No desoldering required.
• Can I use this for an ESP32 programming jig?
  Absolutely. It is the industry standard choice for making contact with ESP32 TX/RX and boot pads.
