The absolute encoder is a position sensor that maps each mechanical position to a fixed digital code, ensuring that different position codes are non-overlapping. It can be read immediately upon power-on and maintains its position when powered off, eliminating the need for zero return. The Fenac FNC series encompasses both single-turn and multi-turn options, supports SSI/BISS/Profibus/CANopen interfaces, and is ideal for industrial applications such as elevators, winding, and lifting, where position retention is essential even when powered off.

The benchtop DC power supply is connected to a computer or test system via interfaces such as LAN, USB, or GPIB, enabling voltage/current setting, readback, and sequence control.

A precision reference component that switches through a dial and provides stepable standard resistance/capacitance/inductance values, commonly used for on-site calibration and teaching verification.

The temperature at which wet air cools down to the point where water vapor begins to condense into liquid water under a certain pressure serves as a direct criterion for assessing the risk of condensation on compressed air, gas pipelines, and surfaces. This temperature is commonly denoted in ℃ Td.

Displacement sensors are used to convert the linear or angular displacement of mechanical objects into measurable electrical signals, serving as the fundamental component for position feedback and closed-loop control. EsiTron offers types such as inductive (eddy current) and magnetostrictive sensors, covering non-contact measurement needs in industrial scenarios like machine tools, hydraulics, and injection molding.

The PicoScope 5000 series and similar models adopt an ADC architecture that allows flexible switching between sampling rate and vertical resolution according to specific measurement tasks.

The Heavy Duty Connector (HDC) is a rectangular or circular multi-pin connector designed for harsh industrial environments. It utilizes metal/thermoplastic housings, locking mechanisms, and modular plug-in cores to provide pluggable, dust- and water-proof electrical interconnection in scenarios such as equipment cabinets, energy, and rail transit. The HARTING Han® series stands as a representative product line of this type of rectangular heavy-duty connector.

A hydraulic rotary actuator is a device that converts the linear motion of a hydraulic cylinder into rotational output, commonly used for angular positioning of turntables, fixtures, and valves.

A pressure switch is a device that switches the state of an electrical contact when the measured pressure reaches a set value. It is commonly used in pump control, air compressors, hydraulic systems, and safety interlocks.

Sound Pressure Level (SPL) represents sound loudness in decibels and is a crucial parameter to consider when selecting alarms and buzzers. It is important to pay attention to the reference distance and weighting method.

A measurement and transmission device that converts air relative humidity and temperature into standard signals (0–10 V, 4…20 mA) or digital bus data (Modbus RTU) for continuous monitoring and adjustment in controlled environments such as clean rooms, computer rooms, and HVAC systems.

A temperature data logger is an independent device equipped with a built-in sensor, memory, and battery, which automatically collects and stores temperature data at preset intervals. It is designed for use in scenarios requiring continuous traceability, such as pharmaceutical and food cold chain transportation, warehouse monitoring, and GSP verification.

The photoelectric sensor, consisting of a separate emitter and receiver, detects the obstruction of the light beam. It boasts a long detection range and strong resistance to background interference, making it ideal for long-distance object presence detection and counting.

A vibration sensor is a measuring component that converts mechanical vibrations into electrical signals, typically outputting IEPE voltage or 4-20mA current, and is used for condition monitoring and predictive maintenance of rotating equipment such as fans, pumps, and motors. The Wilcoxon PC420 series belongs to the two-wire 4-20mA output type.
