The SS360PT, SS460P and SS460P-T2 High Sensitivity Latching Hall-effect Sensor ICs with Built-in Pull-up Resistors are small, sensitive, and versatile devices that are operated by the magnetic field from a permanent magnet or an electromagnet. They are designed to respond to alternating North and South poles. The SS360PT is turned on by a North pole while the SS460P and SS460P-T2 are turned on by a South pole.These products offer reliable switching points with a high magnetic sensitivity of 30 Gauss typ. (55 Gauss max.). They do not use chopper stabilization on the Hall element, providing a clean output signal and a faster latch response time when compared to competitive high sensitivity Hall-effect latching sensor ICs that do use chopper stabilization.The internal pull-up resistor often eliminates the need for external components, helping to reduce the system cost. These high-performance, yet economical, sensor ICs are well suited for demanding, cost-sensitive high-volume applications. These products offer reverse polarity protection, deliver a stable output over a wide temperature range, and can operate from a dc supply voltage from 3 Vdc to 24 Vdc.
