Output frequency stability is crucial for the correct operation of the circuits they are used in.

Connectors:

Connectors are used to establish electrical connections between different parts of an electronic device or between different devices:

Card Edge Connectors, D-subminiature, RJ11/45, BNC, and USB are some common types of connectors.

They are characterized by the number of contacts, pitch (distance between contacts), and mating cycles (how many times they can be connected and disconnected without failure).

Sensors:

Sensors are used to detect changes in the environment and convert them to electrical signals:

Types of sensors include Accelerometers for motion detection, Gyroscopes for orientation, Proximity Sensors, Ambient Light Sensors for lighting conditions, and Hall Effect Sensors for magnetic field detection.

Important parameters are sensitivity, dynamic range, accuracy, linearity, and hysteresis, which affect how the sensor performs in different conditions and applications.
