What is an Electronic Chopper?

An Electronic Chopper (CHOPPER,ELECTRONIC) is an electromechanical or electronic (includes solid state semiconductor items) device designed to convert an electrical signal into a modified square wave output signal. For items excited by an alternating current, the output signal is the same frequency as, and bears a definite phase relationship to, the excitation voltage. For those electronic items designed to operate on direct current only, the output frequency of the item is dependent upon the inherent properties of the item, or the internal or external circuit constants, or the applied driving coil voltage impressed on the input signal. For an electromechanical item whose coil is designed for direct current only, see VIBRATOR, INTERRUPTER and VIBRATOR, SELF-RECTIFYING.

What is a Solenoid Plunger?

A Solenoid Plunger (PLUNGER,SOLENOID) is a metallic item used as a core which reacts to the magnetic flux produced by a surrounding electrical coil(s). It travels on a longitudinal plane with reciprocating motion to perform a mechanical function. It may have facilities for attaching mechanical and/or electrical items such as linkage and/or contacts. It is a maintenance part for such items as RELAY, SOLENOID; RELAY-SOLENOID, ENGINE STARTER, ELECTRICAL; and SOLENOID, ELECTRICAL.

What is a Resonant Reed Relay?

A Resonant Reed Relay (RELAY,RESONANT REED) is an item consisting of one or more metallic reeds, mechanically resonant at a specific frequency and mounted in a permanent magnetic field. Actuation of the relay occurs when an alternating current signal at the resonant frequency of one of the reeds is introduced into a field winding. Excludes RELAY, ELECTROMAGNETIC.

What is a Reed Relay?

A Reed Relay (RELAY,REED) is a relay consisting of an energizing coil and a metallic reed switch mechanism. The reeds serve as both core and contacts, which are not hinged or pivoted and which move by flexure when acted upon by a magnetic field induced by energization of the coil. It may also include a biasing magnet. The biasing magnet, either aids or opposes the movement of the reeds and the opening or closing of the contacts. For items in which actuation is dependent on the resonant frequency of the reeds see RELAY, RESONANT REED. Excludes RELAY, ELECTROMAGNETIC.

What is a Hybrid Relay?

A Hybrid Relay (RELAY,HYBRID) is a self-contained device that performs the function of opening or closing an electrical circuit in response to electrical changes in an external circuit. It consists of a combination of semiconductor and passive circuit devices, which in turn control an integral electro-magnetic relay. Excludes relays which employ diodes, rectifiers or other passive devices to achieve contact protection or coil modification. Excludes RELAY, SOLID STATE.

What is a Solid State Relay?

A Solid State Relay (RELAY,SOLID STATE) is a self-contained device that performs the function of opening or closing an electrical circuit in response to electrical changes in an external circuit. In lieu of separable contacts and their actuator(s), the switching function is accomplished by means of an arrangement of semiconductors and passive circuit devices. The device is designed to have electrical isolation between control circuit and output circuit. Excludes RELAY, HYBRID.

What is an Electromagnetic Relay?

NATO Supply Class 5945 is a classification within NATO Supply Group 59, which is dedicated to Electrical And Electronic Equipment Components.

Specifically, NATO Supply Class 5945 focuses on Relays And Solenoids. Relays are electrical switches that use an electromagnet to control the flow of current in a circuit. They are commonly used to control high-power devices or to switch between different circuits. Solenoids, on the other hand, are devices that convert electrical energy into mechanical motion. They typically consist of a coil of wire wrapped around a metal core and are used in various applications such as valves, locks, and actuators.

In the context of NATO supply classification, Class 5945 includes a wide range of relays and solenoids that are used in military and defense equipment. These components are essential for the proper functioning of electrical and electronic systems in various military applications, including communication systems, radar systems, weapon systems, and more.

The classification system helps in standardizing the identification and procurement of these components across NATO member countries. It ensures that the right components are available for military operations and facilitates interoperability among different nations.

If you need more specific information about a particular relay or solenoid within NATO Supply Class 5945, please provide more details, and I'll be happy to assist you further.
