Specification and Application Equipment Selection Reference for 0.5mm-3mm Spring Pogo Pins

In the field of precision connections for electronic devices, the specifications of spring pogo pins directly impact the stability and adaptability of connections. The commonly used specification range of 0.5mm-3mm covers application scenarios from miniature to medium-sized. Below is a detailed breakdown of key selection points!

1. 0.5mm-1mm Ultra-Miniature Specification

These spring pogo pins feature a slender diameter, making them ideal for devices with extremely strict space constraints, such as TWS Bluetooth headsets, smart bracelets and other wearable devices, as well as micro-cameras and sensor modules. Their primary advantage lies in space-saving design and compatibility with small circuit boards. However, they have limited current-carrying capacity, making them suitable for low-power signal transmission scenarios.

2. 1mm-2mm Universal Specification

As the most common specification, 1mm-2mm spring pogo pins strike a balance between performance and size. They are widely used in consumer electronics such as mobile phones and tablets, applicable for battery connections, charging interfaces, antenna contacts, etc. In industrial handheld devices and medical monitors, they are a mainstream choice due to reliable contact stability and moderate plugging/unplugging durability.

3. 2mm-3mm High Current-Carrying Specification

Larger-diameter spring pogo pins excel in high-current transmission, suitable for power connections in new energy vehicle battery management systems, wireless charging bases, and industrial automation equipment. They feature stronger spring pressure and a larger contact area, capable of withstanding high current loads and vibration/impact in harsh environments.

Ø Reference for Key Selection Parameters

Ø Selection Tips: Besides diameter, pay attention to spring pressure, coating materials (e.g., gold plating, nickel plating), and working temperature range. Evaluate comprehensively based on the device’s usage environment and performance requirements.
