Frequently Asked Questions (FAQ)

Q1: What is the key advantage of a metal sealed relay over a plastic epoxy-sealed one?

A1: Metal hermetic sealing provides a true barrier against gas and moisture permeation over time, which is critical for long-term reliability in vacuum/low-pressure (high-altitude) applications and corrosive atmospheres. It offers superior performance in extreme thermal cycling, making it the only choice for core Military Aviation Contactor applications.

Q2: Can the JKB-53A/TKE-53A be used for both signal switching and power switching?

A2: Yes. Its design specifically accommodates both. It has a proven high-cycle life for 1A power loads and is equally rated for reliable low-level (dry circuit) signal switching down to microamps, making this Precision JKB-53A TKE-53A Relay highly versatile within a single platform.

Q3: How does the lightweight (<3g) benefit my aerospace application?

A3: Weight reduction is paramount in aerospace. Every gram saved contributes to increased payload capacity or extended flight range. Our relay delivers full military-grade robustness without the weight penalty, ideal for drones and satellites.

Q4: What quality documentation is provided with the product?

A4: Standard shipments include Certificate of Compliance (CoC) with key electrical parameters. For qualified defense projects, we can provide test data reports (TDR) and material certifications upon request.

Q5: Is this relay suitable for new high-reliability commercial aerospace programs?

A5: Absolutely. While designed to military standards, its performance and reliability make it an excellent, cost-effective choice for demanding commercial Aviation Engine and avionics systems requiring long service intervals and certification to stringent aerospace standards.
