Altimeter for Missile Application

Introducing the FoldIR 30-450mm f/3.4 continuous zoom lens with Ophir's innovative folded optical design, offering lightweight, compact design while maintaining long optical lengths and improved tolerance sensitivity. This design ensures exceptional performance even in challenging environments, addressing stabilization and athermalization issues. Its unique f/3.4 aperture guarantees superior image quality, surpassing larger aperture zoom lenses in diffraction limit MTF and IR signal collection. The lens features a built-in mechanical shutter for NUC control, enhancing image quality through Ophir's control system. Weighting under 2kg, offering an impressive detection range of over 20km, and a horizontal field-of-view of 26.9º (WFOV) and 1.7º (NFOV). This compact, lightweight, long-range, high-performance lens is the ultimate selection of for optical air-land-sea optical gimbals and payloads. Key features include: • Efficient folded optics design for min. volume use • Physical shutter for NUC • Designed for MWIR 10μm SXGA sensors • For air-sea-land gimbals and payloads • Weight <2kg • Detection range >20km • HFOV 26.9º WFOV/ 1.7º NFOV

aviation fuel refueling cart : Mobile refueling cart that can easily refuel light aircraft and helicopters Sump recovery system : Collect the drained/sumped aviation fuel from the aviation fuel refueling system, easily sample and test it, and then decide whether to drain it or return it to the system. Aviation fuel refueling system : The aviation fuel refueling system is compactly constructed with a skid for easy use and installation.

The D56M differential pressure switch provides high precision measurement across a wide range of low-differential pressure conditions in a package smaller than other units of comparable capability. The membrane senses changes between the “high” and “low” pressure inlets while offering excellent repeatability and high cycle life. Optional hermetically sealed contacts mean the D56M can be well suited when vapor ignition is a concern.

Typical uses include airflow control plenums.

For a similar switch with a higher resistance to shock and vibration, refer to the D16M

For qualification information, please consult the sales or engineering departments.
