The SC2462SO with Magnetic Sensors SOT-23 RoHS is a four-pin surface mount device (SMD) manufactured by Semiment. It is a biased Hall Effect switch designed for use as a low current switch in non-contact sensing applications. It is equipped with a low-power internal voltage regulator for using with a single supply voltage in the range of 1 to 24 VDC, or it can be omitted to work with dual supply voltage of 2.7 to 5.5 VDC. In an open circuit, it has a high on-state resistance, minimizing detected leakage current. Its built-in hysteresis feature makes it immune to vibration, temperature change, and noise. The device is also RoHS compliant for ease of handling for large volume production.
