About
The Dcubed Nano Release Nut (nD3RN) is a highly compact and powerful Shape Memory Alloy (SMA) based release actuator designed for securing sensitive equipment during launch and safely releasing it once in orbit. It is available in two material options: Stainless Steel or Aluminum-Titanium. This device is highlighted as one of the smallest yet most powerful High-Reliability Release Mechanism (HDRM) solutions on the market. A key feature is its resettability, allowing for on-ground and in-space resetting up to 400 times in seconds. It boasts fully redundant actuation and utilizes a smart SMA trigger, resulting in ultra-low shock during release. The nD3RN offers customizable interfaces and is readily available as a Commercial Off-The-Shelf (COTS) part with a short delivery time of 6-8 weeks. It is ITAR Free, simplifying export processes. Its robust design is evidenced by its proof load capabilities and wide operating temperature range.
