A 1.6mm stroke pogo pin is a type of spring-loaded connector designed for applications that require a longer compression range, or “stroke,” than standard pogo pins. The stroke refers to the total distance the plunger can travel from its initial free position to its fully compressed state. A 1.6mm stroke is considered an extended travel pin, making it ideal for scenarios with a greater tolerance for misalignment or for connecting to recessed contacts.

The ability to maintain a reliable connection over a longer travel distance is a key advantage of this type of pogo pin. This feature makes them highly suitable for rugged environments and devices where perfect alignment is not always possible.

Key Features and Applications

• Extended Travel: The 1.6mm stroke allows the pogo pin to compress further. This provides a more forgiving and reliable connection. It also compensates for manufacturing tolerances and physical shock more effectively than shorter-stroke pins.
• Stable Contact: Even with a longer stroke, a well-designed pogo pin maintains a consistent and stable contact force. The spring provides the necessary pressure to ensure a low-resistance electrical connection throughout the entire travel range.
• Durability: Like all high-quality pogo pins, these pins are built with durable materials and are often gold-plated. This ensures resistance to corrosion and wear, which is essential for products that undergo frequent mating cycles.

1.6mm stroke pogo pins are commonly used in a variety of industries:

• Medical Devices: They are crucial for portable medical equipment that needs a reliable connection despite handling and movement.
• Industrial and Ruggedized Equipment: These pins are ideal for devices used in harsh environments where vibration and physical stress are common.
• Battery Connections: The longer stroke helps to ensure a solid connection to battery terminals, which may have slight variations in their position.
• Testing Fixtures: They are also used in test fixtures to accommodate variations in PCB thickness and to make contact with deeply recessed test pads.
