CII solenoids have been custom-designed and built to exacting aerospace and government specifications for more than 50-plus years. These "top-end" devices are engineered for applications where extreme temperatures and other severe environmental conditions may exist. High altitude, shock, acceleration and vibration associated with aircraft and missile systems are conditions which our solenoids meet with predictable reliability.

CII solenoids are used extensively in various types of air, fuel, and hydraulic valve actuators in aircraft, aerospace, medical equipment and other high reliability applications. Other typical uses include door locking and unlocking, hatch and fin latching/unlatching mechanisms, bomb rack and thrust reversing interlocks, engine throttle control and other critical designs.
Product Options
Our linear motion, tubular solenoid line ranges from models only one-half inch in diameter producing ounces of force at short strokes, to three-inch diameter models capable of 100 pounds force at one-inch strokes. Push, pull or combination motion is available.
Continuous or intermittent coils for virtually any DC voltage typically encountered in aerospace applications can be provided. AC voltages can be handled, as well, through the use of internal rectifiers. Dual coil models with low holding power may be appropriate in power sensitive equipment.
For service in harsh environments, we can build solenoids with plunger seals. As required, we can make solenoids water-resistant, fuel-resistant and with encapsulated coils. All ferrous parts are plated for protection against corrosion.
We use 200°C magnet wire insulation as our standard, and we offer higher-rated insulation as an option. Coil leads are normally provided with TEFLON or TEFZEL insulation, or we can use customer-specified mil-type connectors on the solenoids.
CII solenoids are nominally rated at 100,000 operations; however, solenoid life is related to load and duty cycle. Trade-offs in application details can provide life into the millions.
The usual operating and storage temperature range of CII solenoids is -65°C to +125°C.
Solenoids may be provided with either a flat or conical plunger face. Our solenoid engineers, with nearly 100 years combined experience, will determine the optimum plunger shape for each application.
We can supply solenoids with plungers that are internally or externally threaded, as well as clevis plungers. Additionally, we can design captive plunger solenoids, as well as units with a spring assist. For mounting purposes we can fit a solenoid with a threaded bushing or with an application-specific mounting flange.
Complete U.S. government approved qualification test facilities are on-site at our North Carolina production facility.
A prototype solenoid, custom built to a customer's requirements, can usually be shipped within 30 days.
