Converts angular position or rotation into digital pulse signals for precise measurement of speed and displacement.

Detects physical changes (e.g., temperature, pressure, or light) and converts them into electrical signals for monitoring or triggering control actions.

Uses mechanical pressing of a metal actuator to open or close electrical circuits, typically for start, stop, or mode selection.

An electronic switching device with no moving parts, using semiconductors to control loads quietly, rapidly, and with high durability.

Protects circuits from overcurrent or short circuits by melting its internal element when current exceeds its rated value.

Efficiently converts AC input to regulated DC output to power control systems and electrical loads.

Electromagnetically controls the opening and closing of high-current AC circuits, ideal for frequent motor starting and stopping.

Connects and disconnects AC circuits manually or automatically, and trips to protect wiring and equipment during overloads or short circuits.
