Description

The Honeywell SS411P is a versatile, board-mount Hall-effect sensor integrated circuit that responds to bipolar magnetic fields. Its operation is based on the Hall effect principle, where a voltage difference is generated across a conductor when a magnetic field is applied perpendicular to the current flow. This IC converts that analog phenomenon into a clean digital output signal, triggered when the applied magnetic flux density crosses its specified operating point between -30 G and 140 G.

Housed in a robust TO-92 package, the sensor is designed for through-hole mounting, offering mechanical stability and ease of soldering. Its capability to function from a 3 Vdc supply makes it ideal for modern low-power electronics and battery-operated devices. The device’s wide operating temperature range ensures reliable performance in applications from industrial controls to automotive systems, providing a durable and precise solution for magnetic sensing needs.

Key Features

  • Precise Bipolar Switching: Accurately detects both north and south magnetic poles within a defined -30 G to 140 G operating window.
  • Low-Voltage Operation: Supports a 3 Vdc supply, enabling integration into energy-efficient and portable electronic designs.

Frequently Asked Questions

What is the operating voltage range for the Honeywell SS411P sensor?

The Honeywell SS411P is designed for low-voltage operation, specifically from a 3 Vdc supply. This makes it highly suitable for battery-powered devices, portable electronics, and other energy-efficient system designs where minimizing power consumption is critical.

How do I interface the SS411P digital output with an Arduino or microcontroller?

The SS411P provides a digital output signal. Connect the sensor's Vcc to a 3V supply (or use a voltage regulator), GND to ground, and the output pin to any digital input pin on your microcontroller (e.g., Arduino, ESP32). The pin will switch logic states (HIGH/LOW) when the applied magnetic field crosses the sensor's operating point threshold.

What does 'bipolar' mean for this Hall-effect sensor?

A 'bipolar' Hall-effect sensor responds to both the north and south poles of a magnet. The SS411P will switch its output state when a sufficient magnetic field of either polarity is applied within its -30 G to 140 G range. This is different from unipolar sensors, which only respond to one magnetic pole.

What is the significance of the operating point range (-30 G to 140 G)?

The operating point range defines the magnetic flux density required to activate the sensor's digital output. The SS411P requires a minimum field strength between -30 G (south pole) and 140 G (north pole) to reliably switch. This specification is crucial for selecting the appropriate magnet strength and air gap for your specific application.

Can the SS411P withstand high-temperature environments?

Yes. The SS411P is rated for an extended operating temperature range of -40°C to +150°C. This industrial-grade temperature resilience makes it suitable for demanding applications in automotive under-hood environments, industrial machinery, and other settings where thermal conditions are extreme.
