Description

The SS41 is a robust digital Hall-effect sensor that responds to alternating North and South magnetic poles, making it ideal for speed sensing, rotary encoding, and position detection in mechanical systems. Its internal voltage regulator ensures stable operation across a broad supply range, while protective circuitry guards against accidental reverse-polarity connection.

Engineered for reliability, the sensor provides a digital sink output that switches in response to magnetic field transitions. This design offers excellent noise immunity and straightforward integration into both industrial automation environments and embedded electronics projects requiring precise magnetic event detection.

Frequently Asked Questions

What is the operating voltage range for the Honeywell SS41 sensor?

The SS41 operates from a wide supply voltage range of 4.5 to 24 volts DC. Its built-in voltage regulator ensures stable performance across this entire range, making it compatible with common logic levels (5V, 3.3V with a pull-up) and standard industrial power supplies (12V, 24V).

What type of output does the SS41 Hall sensor provide?

The SS41 provides a digital, current-sinking (open-collector NPN) output. When activated by a magnetic field, the output transistor sinks current to ground. This requires an external pull-up resistor to Vcc (compatible with the sensor's supply voltage) to provide a logic-high signal to your microcontroller or PLC input.

How do I connect and use the SS41 with an Arduino or Raspberry Pi?

Connect Vcc to your board's 5V (or 3.3V with a suitable pull-up), GND to ground, and the output pin to a digital input pin on your microcontroller. You must add an external pull-up resistor (e.g., 10kΩ) between the output pin and Vcc. The sensor will pull the line low when a magnetic South pole is detected.

What is the difference between unipolar and bipolar Hall sensors?

A unipolar sensor activates in the presence of one magnetic pole (e.g., South) and deactivates when the field is removed. A bipolar sensor, like the SS41, switches its output state in response to both North and South poles, making it ideal for detecting alternating magnetic fields in applications like speed sensing and rotary encoding.
