SS466A-S Datasheet/PDFMagnetic sensors are an important part of many applications. They range from everyday equipment found in automotive, consumer, and industrial devices, to specialized instruments used in aerospace and medical venues. The SS466A-S magnetic sensor switch is one such device that combines low power consumption with high performance.
The SS466A-S is a solid state analog switch that uses an open-drain output to drive an electromechanical relay or logic circuit. The device has two active-low inputs: one for power supply select and the other for external signal. The power supply can be any of the common 5V or 3.3V types, depending on your requirement. The external signal input is a magnetic field monitored by a Hall effect sensor. The strength of the magnetic field can be measured in millivolts, allowing for a range of sensitivity.
The SS466A-S provides three different operating modes: single, double and quad, which all respond differently to magnetic inputs. Single mode uses a single Hall effect sensor, which switches polarized at a certain magnetic field strength. Double and quad mode both use two Hall effect sensors, with the double mode switching with a change in the difference between the two signals while the quad mode switches with a change in the ratio between the two signals. The SS466A-S also comes with an adjustable dead band, allowing for greater control over the sensitivity of the switch.
The SS466A-S is an ideal device for applications where low power consumption, high performance and precision are required. The switch is suitable for use in medical, automotive and industrial applications, including motor detection, level sensing, proximity sensing, pressure sensing, and more. It is also useful in aerospace applications such as vision systems, attitude control, and airspeed measurement.
The power supply used with the SS466A-S must be stable and have minimal ripple voltage. Output must also be free from noise, with the correct filtering to reduce the risk. When operating the SS466A-S switch, the magnetic field should be kept away from any metallic objects, and the switch should be supplied only with an approved power supply.
