Spring probes provide reliable electro-mechanical performance through hundreds of thousands of cycles. They are available in a variety of sizes, spring forces and terminations. Smiths Interconnect compression mount connectors utilizing spring probe technology offer tremendous advantages in reliability, performance and efficiency in comparison to conventional technologies like stamped metal, wire mesh, pin-and-socket or elastomer. Standard spring probes offering includes battery contact and connector probes designed to optimize contact performance in high-reliability, multiple-cycle interconnect applications.

EM21 is designed to be used behind the EOST EDS Red Dot Reflex Sight. EM21 can be mounted right behind the EOST EDS (or any of other dot and holographic sight) to give 3 times magnifying view. EM21 helps shooter convert the optical magnification so that he can have better target acquisition and fast target engagement capability. The ability to transition between the two distances almost instantly and still maintain weapon accuracy is easily achieved with our EM21. Simply switch the magnifier out of the way for a quick 1X targeting. EM21 can be used for hunting/recreational purpose.

Ultra-High Accuracy MEMS Certus Evo features some of the highest accuracy MEMS accelerometers and gyroscopes currently available. Certus Evo’s inertial performance exceeds some FOG IMUs and is up to 100x smaller and 10x cheaper.

The Haigh-Farr Wraparound™ is a self-contained omnidirectional antenna for cylindrical or conical shaped bodies. A single point feed is used and no external splitters, combiners or cable harnesses are required for installation. The antenna is conformal, and may be mounted flush, or on the exterior of the vehicle. Designs are available from 300 MHz to 13 GHz with typical applications including Flight Termination, GPS, Telemetry, Data Links and Transponder. Multiple antenna elements may be combined within the same physical Wraparound™, providing multi- band capability in a single, compact package. Wraparound™ antennas have been flown on vehicles from subsurface sea to space, including high-mach kinetic kill weapons, high-G projectiles and re-entry vehicles. The Wraparound™ has been qualified for use on several high performance vehicles flown on test and launch ranges throughout the United States and Europe. For high aero-heating applications an ablative heat shield may be added to the antenna for additional thermal protection.
