Frequently Asked Questions (FAQ)
Q
What makes the 0.65mm Twisted-Pin contact design superior to standard contacts?
The Twisted-Pin design creates multiple redundant contact points simultaneously, which results in lower and more stable contact resistance compared to a single-point contact. Its inherent springiness also provides superior vibration resistance and extends mating cycle durability, making it highly reliable in demanding environments.
Q
Why is the 1.3mm pitch important for modern electronic designs?
The 1.3mm pitch enables significant miniaturization and high contact density within a small footprint. This is essential for modern space-constrained applications such as avionics, portable military devices, and compact medical equipment, where reducing size and weight without sacrificing reliability is critical.
Q
What are the benefits of crimp termination over other connection methods?
Crimp termination forms a gas-tight mechanical bond between the conductor and the contact, which prevents oxidation and ensures a consistently low-resistance connection over time. It is particularly well-suited for flexible cables and provides strong resistance to failure from vibration, pulling forces, and other mechanical stresses encountered in harsh environments.
Q
Why is a thermosetting plastic insulator used instead of a standard thermoplastic?
Thermosetting plastics offer superior thermal stability compared to standard thermoplastics — they do not soften or deform at high soldering or operational temperatures. They also provide excellent dielectric (electrical insulation) properties and resist environmental aging, ensuring that the insulator maintains its integrity and performance over the full service life of the connector.
Q
Are these connectors suitable for use in medical devices?
Yes. These connectors are listed under high-reliability industrial equipment applications, which explicitly includes medical devices. Their combination of miniaturization, stable contact resistance, vibration resistance, and compliance with military-derived standards makes them an excellent choice for precision medical instruments and diagnostic equipment.
Q
What standards do these connectors comply with, and why does it matter?
These connectors comply with a stringent military-derived standard. This is significant because military standards impose rigorous testing and performance requirements covering temperature extremes, vibration, shock, humidity, and other environmental factors. Compliance with such a standard provides engineers and procurement teams with high confidence in the connector's long-term reliability for critical interconnection applications.
