The Aerospace & Defense Team's Business Service Providers (BSP) Directory is designed to help U.S. aerospace & defense companies identify professional service providers to assist them in the assessment, completion, and/or financing of an export transaction.

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.

Features

Intended for gaseous media
Environmentally sealed with optional hermetically sealed contacts
Proven diaphragm and leaf spring technology for high cycle life

A lightweight high tensile aluminium frame, suspended by elastomeric anti-vibration mounts, provides superior ‘sway-space’ between the frame and the outer container and is the best possible way to safeguard delicate equipmentMore robust and stainless steel variants are custom-made for heavy payloads and corrosive environments. Enhanced ‘sway space’ between inner frame and outer case to prevent contact with outer container All our 19 inch Amazon Racks have a ‘user adjustable’ inner frame allowing back to front movement of 50mm within the outer container to accommodate front panel and rear wiring/ connector needs. Optional ‘EasyGlide’ removable, self anchoring, internal frame system Standard, stainless steel M6 threaded fasteners secure electronic equipment into floating stainless steel cage nuts at both front and rear of frame. All our 19 inch Amazon Racks have positive stacking, aligning at the front face regardless of rack depth

Adjustable stator vanes that control airflow angle entering the rotor blades.

Powering front-line fighters globally and backed by a continuous infusion of new technology, the F110 remains the engine of choice around the world.

Vehicle-type RF Jammer Systems provide protection to VIPs and convoys against remote-controlled explosives. These systems create a protective shield through RF broadcasting and neutralize threats activated by radio, mobile phones and wireless remote-controlled devices. Vehicle-type RF Jammer Systems can be easily integrated aboard all kinds of vehicles, and allows for reprogramming against changing situations.

Our XR-based aircraft maintenance simulator is officially certified by the Ministry of Land, Infrastructure and Transport (MOLIT) of South Korea for training and education. It provides specialized training environments for the A321, B737-MAX, and B737-800NG aircraft, featuring over 80 detailed modules—including procedures for engine removal, main landing gear installation, and more. This subscription-based simulator is fully compatible with smartphones, tablets, and wearable XR devices, enabling seamless access through a cloud-based web service. Users can train anytime, anywhere—perfect for both remote learning and remote maintenance scenarios. Compared to traditional classroom learning, the XR platform is 4 times more effective and requires only one-third the training time. It also improves user confidence in real-world technical applications by up to 275%. By transforming traditional paper manuals into immersive, interactive training environments, the simulator delivers the next generation of aircraft MRO education for both civil and defense sectors.

Lumir, in collaboration with the Electronics and Telecommunications Research Institute (ETRI), developed and integrated this device for lunar exploration aboard Danuri (KPLO, the Korea Pathfinder Lunar Orbiter), Korea's first lunar probe. This device successfully demonstrated its performance by receiving BTS music videos transmitted from the Moon to Earth, achieving Technology Readiness Level (TRL) 9.
