Absolute rotary encoders use optical, mechanical, or magnetic indexing for angular measurement. They do not lose their position after power-down, but instead provide absolute position upon power-up without requiring a home cycle or any shaft rotation.
|
|
AC motor drives interface controllers to AC motors. They match the control signals (voltage and power levels) as well as the signal type (analog or digital). They also provide power conversion, amplification, and the sequencing of waveform signals.
|
|
AC servomotors are responsive, high-acceleration motors typically constructed as permanent magnet synchronous motors.
|
|
AC-DC adapters accept AC input voltage directly from a wall outlet, and output DC voltage.
|
|
Ballasts are electrical devices that condition the line voltage (amplitude, amperage and waveform) to operate fluorescent and HID lamps. Basically they serve two functions: to provide the starting kick, and to limit the current to the proper value for a particular lamp.
|
|
Counter and timer boards are computer cards that perform digital counting and/or timing functions.
|
|
Current sense transformers are used to detect and measure current. There are two basic types of products: switch-mode transformers for power conversion applications, and precision-measurement transformers for instrumentation applications.
|
|
DC motor drives act as the interface and power supply between a motion controller and a DC motor.
|
|
DC motors are most commonly used in variable speed and torque applications. They include brushless and gear motors, as well as servomotors.
|
|
DC-DC converters accept DC input and provide regulated and/or isolated DC output in various applications including computer flash memory, telecommunications equipment, and process control systems.
|
|
Electronic cooling fans move air to cool electronic devices.
|
|
Electromagnetic (EMI) filters and radio frequency interference (RFI) filters purify signals by attenuating the high-frequency RFI (typically 150kHz and up) and passing the low frequency EMI.
|
|
Fiber optic transceivers include both a transmitter and a receiver in the same component.
|
|
Flat panel displays (FPDs) are thin, flat, electronic devices used to display data. They are commonly used in notebook computers. Most styles include the housing and ports necessary to connect them to a computer.
|
|
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.
|
|
Human machine interfaces (HMI) are operator interface terminals with which users interact in order to control other devices.
|
|
Incremental rotary encoders are multi-turn sensors that use optical, mechanical, or magnetic index-counting for angular measurement. They contain no absolute reference, but instead count relative to the turn-on position.
|
|
Inductors coils and chokes are passive components that are designed to resist changes in current and store energy in the form of a magnetic field.
|
|
Industrial computer monitors are ruggedized for use in control room, factory floor, or process applications.
|
|
Lamps are light sources that emit incoherent light for illumination. There are many different types of products. Examples include fluorescent lamps, halogen lamps, heat lamps, incandescent lamps, LED lamps, projection lamps, spectral lamps, and stage lamps. Specialized and proprietary lamps are also available.
|
|
LED lamps are light emitting diode arrays with traditional lamp ballasts.
|
|
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.
|
|
Programmable logic controllers (PLCs) are the control hubs for a wide variety of automated systems and processes. They use a wide variety of inputs and outputs and provide network capability.
|
|
Projectors receive data from a computer or video source and project this data onto a screen via internal light sources, power sources and converters.
|
|
Pulse transformers interface a pulse forming network (PFN) and a load. They match the impedance of the load to the PFN in order to maximize power-transfer efficiency.
|
|
RF modules are partially finished circuits that can be incorporated into larger designs.
|
|
Stepper motors use a magnetic field to move a rotor in small angular steps or fractions of steps. They provide precise positioning and ease of use, especially in low acceleration or static load applications.
|
|
Tachometers are used to measure the velocity of a rotating object. They operate on the principle that a driven motor (i.e., a motor operated as a generator) produces a voltage that is proportional to the angular velocity of the motor shaft.
|
|
Temperature controllers accept inputs from temperature sensors or thermometers, and then output a control signal to keep the temperature at the desired level.
|
|
Three phase uninterruptible power supplies (UPS) operate in conjunction with existing electrical systems to provide power conditioning, back-up protection, and distribution for electronic equipment loads that use three-phase power.
|
|
Uninterruptible power supplies (UPS) are backup batteries that provide emergency power to electrical systems in case power becomes unavailable. They are connected between a power source (such as an electrical outlet) and the equipment to protect (such as a motor or computer).
