Audible alarms provide an audible indication of a hazardous situation.
|
|
Capacitors are electronic components used for storing charge and energy. In their simplest form, capacitors consist of two conducting plates separated by an insulating material called the dielectric.
|
|
Circuit protection devices are used to protect electronic components from unwanted transients such as current and voltage surges, electrostatic discharge (ESD), lightning, spikes and other signals that can imperil the operation or damage the component.
|
|
Coaxial cables have one conductor insulated with a dielectric material and then surrounded by the other conductor, usually referred to as the center conductor and shield. Triaxial cables are specialized coaxial cables.
|
|
Crystals are naturally occurring materials that can be induced to resonate (vibrate) at an exact frequency. Quartz, a piezoelectric crystal that provides excellent mechanical and electrical stability, acquires a charge when compressed, twisted, or distorted.
|
|
Electrical connectors are devices that join electrical circuits together. Male connectors plug into receptacles, jacks, and outlets. Female connectors contain sockets to receive other devices.
|
|
Electromechanical counters and electromechanical timers accept inputs to operate mechanical display, such as rotating wheels or knobs.
|
|
Electromechanical relays are devices that complete or interrupt a circuit by physically moving electrical contacts into contact with each other.
|
|
Electronic enclosures and instrument enclosures house electronic components and instruments. They are usually designed for handheld or desktop applications.
|
|
Electronic cooling fans move air to cool electronic devices.
|
|
Flat cables are typically used in computers for internal connections to peripherals. They are also referred to as ribbon cables.
|
|
Fuse holders are devices for containing, protecting and mounting fuses. Blown fuses can be changed quickly and easily when used in conjunction with a fuse holder.
|
|
Fuses protect electrical devices and components from overcurrents and short circuits that occur in improperly operating circuits.
|
|
Heat sinks are thermally conductive, usually metallic components or devices that absorb and dissipate heat generated by electronic components such as computers. Common heat sink materials include aluminum, copper, and steel.
|
|
Hookup wires are used in low current, low voltage (under 1000 V) applications within enclosed electronic equipment. They are also used in control panels, meters, computers, business machines, and appliances.
|
|
Inductors, coils, and chokes are passive components designed to resist changes in current and store energy in the form of a magnetic field.
|
|
Industrial batteries translate chemical energy into electricity.
|
|
Industrial enclosures are used to house electronic components, equipment and devices. They are designed to protect personnel from accidental injury and to prevent the ingress of environmental contaminants.
|
|
Multiconductor cables contain two or more conductors, each of which consists of a single wire or combination of wires. Cable shielding is placed around an insulated conductor or group of conductors to prevent electrostatic or electromagnetic interference between the enclosed wires and external fields.
|
|
Oscillators are devices that are used to generate repetitive signals. They produce output signals without an input signal. There are two major types of electronic oscillators: harmonic oscillators and relaxation oscillators. Harmonic oscillators produce sine wave outputs. Relaxation oscillators produce non-sine wave outputs such as square wave, rectangular wave, and sawtooth outputs.

|
Potentiometers, rheostats and trimmers are three-terminal resistors that are used to measure or divide voltages, and to protect or control circuits.
|
|
Power cables are solid or stranded conductors surrounded by insulation, shielding, and a protective jacket. These cables are designed for high voltages (>600 V).
|
|
Power supplies are devices that produce AC or DC power. This grouping includes current sources, DC power supplies, AC-DC adapters, DC-DC converters, AC power sources, and DC-AC inverters.
|
|
Power transformers convert power-level voltages from one level or phase configuration to another. They can include features for electrical isolation, power distribution, and control and instrumentation applications.
|
|
Resistors are electrical components that oppose the flow of either direct or alternating current. They are used to protect, operate, or control circuits.
|
|
Resistors and potentiometers are passive electronic components that oppose the flow of either alternating current (AC) or direct current (DC).
|
|
Signal transformers transfer information from one circuit to another by electromagnetic induction. They are used to increase or decrease the voltage from one side of a power transformer to the other.
|
|
Terminal blocks are modular, insulated blocks that secure two or more wires together. Terminal blocks consist of an insulating body and a clamping device. Their flexibility allows wiring to be centralized and makes it easier to maintain complex control circuits.
|
|
Single phase uninterruptible power supplies (UPS) sit between an AC outlet (i.e., a wall outlet or power strip) and an electronic device (e.g., computer, server, or phone equipment) to provide power conditioning, back-up protection and distribution for electronic equipment loads.
|
|
Bare conductor wire and cable conductors are constructed from conducting materials to carry electric current. They are available in two styles; solid conductor or several conductors twisted or braided together for added flexibility.
