🔌 9–65 Cores
📳 Vibration: 10–2000Hz, 196m/s²
💥 Shock: 196m/s²
- 1 The J63A series mini-rectangular connectors feature twist-pin contact, bolt-nut locking, 0.635mm pitch (9–65 cores), and −55°C ~ +125°C tolerance, resisting vibration (10–2000Hz, 196m/s²) and shock (196m/s²).
- 2 They are ideal for aerospace circuits, portable medical devices, and industrial instruments needing high-density, stable connections in tight spaces.
✅ Advantages
- 1 Compact and light in weight, compatible with 0.035mm² wires. Ensures reliable signal transmission with ≤2MΩ contact resistance and 500MΩ insulation.
- 2 Unmatched combination of compactness, mechanical reliability, and environmental sealing — an outstanding choice for harsh environments, especially in the automotive sector.
- 3 Its success is a testament to its design meeting the rigorous demands of modern electronic systems.
🏭 Applications
- 1 Applications are overwhelmingly skewed towards mission-critical, harsh-environment electronics. Its dominance in the automotive sector cements its reputation as a connector for serious engineering.
- 2 Primarily applied in mezzanine board connections — the most classic use. Allows a secondary PCB to be stacked directly on the main motherboard, saving enormous horizontal space.
- 3 Applied in high-density interconnections in compact devices where space is at an absolute premium and many signals need to pass between two closely spaced boards.
