Hermetically Sealed Relays

Subminiature Relays (Low level to 75 Amps)

For decades, LEACH® subminiature relays have set the industry standard for technology and reliability. With their proven high performance in the most demanding applications, they are ideal for critical subsea, shipboard, ground-based, space, and aerospace applications .

Balanced Armature Relays (10 Amps to 25 Amps)

LEACH® balanced armature relays have been used in commercial and military aircraft, trucks, buses, ships, and tanks – applications that call for proven durability, high performance and long life. Several terminal mounting styles, dust-resistant, moisture-resistant and hermetically-sealed enclosures. A variety of operating ratings and characteristics are available.

Power Contactors (25 Amps to 700 Amps)

LEACH® power contactors are available with optional auxiliary contacts in sealed and unsealed models. “Smart” programmable contactors and special mounting styles are also available.

Time Delay Relays (150 mAmps to 25 Amps)

Time delay devices combine the proven capability of industry standard relays with highly reliable hybrid microelectronics timing circuits.

Power Monitors and Sensors (up to 10 Amps)

Designed to meet the requirements of MIL-R-28894, LEACH® power monitors and sensors constantly monitor and protect critical AC or DC circuits.

Solid-state Power Controllers (1 Amp to 220 Amps)

Ideal for applications where reliability is key and size and weight are major concerns; LEACH® SSPCs employ a FET output stage and are constructed using thick-film technology, they are hermetically sealed, and mainly metal enclosures.
