The CH411TB with TO-92S Hall Sensor ROHS is a small Hall effect switch manufactured by Cosemitech. It is a sensitive integrated switch that produces a digital output when exposed to a magnetic field. This output is used to detect changes in the magnetic field strength, indicating the presence of a ferrous pole, a moving object, or even a minor field gradation. It is ideal for use in motor control, positioning sensing, position switches, and current sensing applications. It is available with an operating temperature range of -40°C to 85°C, and required a supply voltage of 3V to 24V. The CH411TB comes in a TO-92S Mini-SIP package with RoHS compliant materials, making it a compact and reliable choice for your sensing needs.
