Honeywell SS41

Honeywell SS41 Environmental and export classification status description

The Honeywell SS41 is a subminiature, bipolar, latching Hall-effect sensor. It is designed to detect the presence or absence of a magnetic field and provide a digital output signal. The SS41 operates on a 4.5V to 24V supply voltage and is capable of detecting both north and south poles of a magnet. Functions: - Presence/Absence Detection: The SS41 can sense the presence or absence of a magnetic field, making it suitable for proximity sensing applications. - Latching Operation: Once the sensor detects a magnetic field, it switches its output state and latches it, retaining the state even if the magnetic field is removed. - Digital Output: The SS41 provides a digital output signal that can be easily interfaced with microcontrollers or other digital circuits. Applications: The Honeywell SS41 sensor is commonly used in various applications, including: 1. Position and Speed Sensing: It can be used in speedometers, tachometers, and gear tooth sensors to measure rotational speed and position. 2. Proximity Detection: The SS41 is used in non-contact switches and sensors for detecting the presence or absence of objects. 3. Magnetic Encoding: It is suitable for encoding in rotary knobs, push-button switches, and other user interface devices. Alternative Parts: Some alternative Hall-effect sensors similar to the Honeywell SS41 are: 1. Allegro A3144: A small, versatile, and easily customizable Hall-effect sensor. 2. Melexis MLX92211: A high-sensitivity Hall-effect latch with a wide operating voltage range. 3. TI DRV5033: An ultra-low-power digital switch with adjustable sensitivity. Embedded Modules: Honeywell also offers embedded sensor modules that incorporate the SS41 sensor, such as the Honeywell SEK001 sensor evaluation kit.
