Magnetic Sensors - Switches (Solid State) are electronic devices used to detect the presence or absence of a magnet or some form of magnetic material. SS443A-L is an advanced low-cost Hall Effect based magnetic switch with a hysteresis curve. It is a reliable, miniature, energy-efficient switch with a low power dissipation of only 13mA. It offers excellent off-state leakage current characteristics and a response to mounting orientations. It is suitable for a wide range of applications.

The SS443A-L is a Hall effect based single pole/single throw (SPST) switch. It utilizes a Hall element to detect the presence or absence of a magnetic field. The presence of the magnetic field causes the output of the device to switch states. When the magnetic field is not present, the device returns to its original state.

The SS443A-L has a wide operating supply voltage range. It can operate from a minimum supply voltage of 2.7V up to 12V. The quiescent current at 12V supply voltage is only 13mA. This device features a Hall effect that is extremely sensitive and with a wide and linear hysteresis curve. The hysteresis curve ensures that the output of the device won\'t toggle state back and forth with small fluctuations in magnetic field.

In addition to its low power consumption, the SS443A-L is constructed with a double-layered ceramic package. This package is ideal because it provides superior protection against moisture and ambient temperature environments. The package also offers excellent electrical insulation properties and is resistant to mechanical shock and vibration.

Applications for the SS443A-L include automotive electronic systems, home door/window intrusion detection, industrial automation, robotic systems, medical monitoring systems, and security systems. The device is also widely used in consumer electronics such as speakers, gaming controllers, and smart energy systems.

The SS443A-L features a latching output option with a single-pole/single-throw (SPST) contacts. When the hysteresis range of the device is exceeded by a magnetic field, the output state of the device changes and is locked until the magnetic field is removed. This feature allows the SS443A-L to be used for latching circuit design, position sensing, and motion detection applications for the automated industry.

Overall, the SS443A-L is an advanced low-cost Hall Effect based magnetic switch with a hysteresis curve. Its rugged construction paired with its low power consumption and latching output make it suitable for a wide variety of automotive, industrial, and consumer applications.
