Products/Services for limiting device current
Current limiting diodes (CLD) regulate current over a wide voltage range. There are several types of current limiting diodes (CLD). Examples include a current regulator diode, constant current diode, and current limit diodes. Search by Specification | Learn More about Current Limiting Diodes
Current sensors measure AC and/or DC current levels. They receive current inputs and provide outputs as analog voltage signals, analog current levels, switches, or audible signals. Search by Specification | Learn More about Current Sensors
Current transformers are used to step down current in a very predictable fashion with respect to current and phase. They are generally used as inputs to current instruments. Search by Specification | Learn More about Current Transformers
Current sense amplifiers are integrated circuits with operational amplifiers and sense resistors that are used in measuring the amplitude and direction of current in circuits. Search by Specification | Learn More about Current Sense Amplifiers
Current sources provide reliable current for electrical component testing and for powering specialized components. Search by Specification | Learn More about Current Sources
Eddy current proximity sensors and switches detect the proximity or presence of a target by sensing the magnetic fields generated by a reference coil. Search by Specification | Learn More about Eddy Current Proximity Sensors
Current-to-voltage converters scale and convert current signal input to the desired output voltage range. Search by Specification | Learn More about Current-to-Voltage Converters
Current leakage testers measure the amount of current that leaks to ground. Search by Specification | Learn More about Current Leakage Testers
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. Search by Specification | Learn More about Circuit Protection Devices
Eddy current instruments are nondestructive testing (NDT) devices that induce detectable eddy currents in conductive materials. They are used to detect flaws, determine thickness, inspect welds, measure conductivity, and sort alloys. Search by Specification | Learn More about Eddy Current Instruments
Analog ammeters are metered instruments that measure current flow in amperes. They display current levels on a dial, usually with a moving pointer or needle. Search by Specification | Learn More about Analog Ammeters
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. Search by Specification | Learn More about Current Sense Transformers
Limit switches are electromechanical or solid state devices that require the physical contact of an object with the switch’s actuator to make the contacts change state. Search by Specification | Learn More about Limit Switches
Rotary limit switches use physically-actuated levers to rotate a shaft and operate the contacts in a switch, making them change state. Search by Specification | Learn More about Rotary Limit Switches
Eddy current linear position sensors detect the distance from a target by using magnetic fields generated by a reference and sensing coils. Search by Specification | Learn More about Eddy Current Linear Position Sensors
