Contacts, Spring Loaded (Pogo Pins), and Pressure Connectors & Interconnects

Definition:
Contacts, Spring-Loaded (Pogo Pins), and Pressure connectors are specialized interconnect components designed to establish temporary or semi-permanent electrical connections through mechanical pressure. These solutions excel in applications requiring repeated mating cycles, compact spacing, or reliable conductivity under dynamic conditions. Pogo pins (spring-loaded contacts) leverage compressed springs to maintain consistent contact force, while pressure-based connectors rely on sustained mechanical pressure for conduction eliminating the need for soldering in many cases.

Types of Products in This Category:
1. Spring-Loaded Contacts (Pogo Pins):
- Single/Dual/Multi-Point Spring Probes
- High-Current Pogo Pins (e.g., battery charging contacts)
- Miniature Coaxial Pogo Pins (RF/testing applications)

Pressure Contacts:
- Conductive Elastomer Connectors (for LCD/PCB interfaces)
- Land Grid Array (LGA) Sockets
- Anisotropic Conductive Films (ACFs)
Hybrid Solutions:
- Magnetic + Spring-Loaded Connectors (e.g., charging docks)
- Self-Cleaning Pogo Pins (oxidization-resistant coatings)

Purchasing Recommendations:
- Current Rating: Verify ampacity matches your load (e.g., 1A for signal vs. 5A+ for power transfer).
- Cycle Life: Industrial applications may require 100K+ cycles; consumer devices often suffice with 10K.
- Contact Material: Gold-plated for corrosion resistance (ideal for harsh environments), beryllium copper for high elasticity.
- IP Rating: Select sealed designs (IP67+) if exposure to moisture/dust is anticipated.
- Alignment Tolerance: For pogo pin arrays, ensure plunger travel distance compensates for PCB misalignment ( 0.5mm typical).

Ideal for test fixtures, wearable devices, and modular electronics where durability and space efficiency are critical.
