Additional Details:

The HSR412SR2M has a built-in Hall element and signal conditioning circuitry. It operates on a supply voltage typically between 3V and 24V. The output switches based on pre-defined magnetic field thresholds. The device is designed to latch its output state until the magnetic field is reversed. External pull-up resistor may be needed, depending on the logic family it is connected to. Consult the datasheet for specific operating characteristics and magnetic field thresholds.

Typical Specifications: The sensor's operating temperature range is typically -40°C to +85°C. The magnetic operate point (Bop) and release point (Brp) are specified in the datasheet, defining the magnetic field strength required for switching. The output is usually an open-collector or open-drain configuration.
