Core offering

Leach International Corporation manufactures power distribution and switching components, including relays, contactors, control devices, sockets, and solid-state power controllers, for aerospace, military, and commercial aviation applications. The company offers a catalog of more than 3,000 active parts qualified to MIL-PRF-6106, MIL-DTL-12883, and MIL-PRF-83726 standards, and provides custom engineering solutions tailored to specific customer power distribution requirements.

Product overview

Leach International Corporation offers a comprehensive portfolio of power distribution and switching components organized into six core product categories: Relays (military-qualified miniature, subminiature, and half-crystal can relays ranging from 0.25A to 75A in DC and AC versions with hermetic sealing), Contactors (high-power units from 25 to 1000 amps in hermetically or environmentally sealed configurations), Control Devices (fixed/adjustable AC/DC time delays, solid-state time delays, programmable time delay devices, and power monitors), Sockets (complementary relay socket accessories), Solid State Power Controllers, and Power Distribution products. The portfolio includes specialized products like the Hyperion-270 hybrid contactor combining electromechanical and solid-state technology, and the CA450 variable frequency contactor for aerospace applications. Products are designed to MIL standards including MIL-PRF-6106, MIL-DTL-12883/48, and MIL-PRF-83726/30. The company catalogs over 3,000 active parts and offers customized solutions.
