How Our Latching Solid State Relays Will Transform The Space Industry
"When the mission is critical, there’s no room for failure."
There are two types of relays in the market, electromechanical and solid-state relays. However, the electromechanical relays have reliability issues.
Our latching solid-state relays (LSSRs) are designed to address many issues encountered in outer space, ultimately saving time, costs and lives.
Precision, reliability and good performance are non-negotiable when it comes to manufacturing space mission products. Failures during launch can jeopardise years of hard work and development, causing delays in research and space exploration.
A single malfunction can endanger missions, drain resources, and, particularly in the realm of space equipment, endanger lives. When you’re pushing the boundaries of technology for a brighter future, incorporating fail-proof components into your designs becomes crucial.
Latching SSRs Vs Mechanical Relays
LSSRs possess superior characteristics compared to mechanical relays. Mechanical relays have been a mainstay in various industries; however, a closer examination reveals that mechanical relays exhibit notable shortcomings.
In the world of space and aerospace engineering, the mechanical relay's vulnerability to failure is its Achilles' heel. Here are six critical reasons why LSSRs outperform their non-latching SSR counterparts:
- Contact Failure: Over time, relay contacts face wear, oxidation, and resistance issues, leading to failures.
- Coil Failure: Burnouts, insulation breakdowns, or mechanical damage can result in catastrophic relay failure.
- Mechanical Failure: Components such as armatures and springs may exhibit erratic behaviour due to wear.
- Environmental Factors: Extreme temperature swings, humidity, dust invasions, and unyielding vibrations can disrupt relay components.
- Welded Contacts: High current or arcing can cause contacts to fuse, resulting in a permanently stuck state.
- Manufacturing Defects: Defects can occur during assembly, leading to intermittent or catastrophic failures.
In the demanding space and aerospace sectors, the mechanical relay’s extensive list of issues starkly contrasts with the steadfast performance and durability of true LSSRs.
In an era where safety is paramount, these risks are unacceptable. Our latching relays offer a safer alternative.
Latching SSRs Advantages
Our LSSRs are designed to have more advantages than standard solid-state relays:
- No Moving Parts: This design eliminates wear and extends their lifespan, enhancing reliability.
- Faster Switching Speeds: They excel in applications requiring rapid response.
- Status Control: LSSRs are microcontroller compatible.
