It outputs an analog voltage proportional to the magnetic flux density applied perpendicular to the branded face. Engineers and makers use it for precise, contactless magnetic field sensing in measurement and positioning systems.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSupply Voltage\u003c\/td\u003e\n\u003ctd\u003e4.5 V to 5.5 V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput Type\u003c\/td\u003e\n\u003ctd\u003eAnalog (ratiometric)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSensitivity\u003c\/td\u003e\n\u003ctd\u003e2.5 mV\/G typical\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eQuiescent Output\u003c\/td\u003e\n\u003ctd\u003e2.5 V at zero field (Vcc\/2)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMagnetic Range\u003c\/td\u003e\n\u003ctd\u003e±1000 Gauss\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePackage\u003c\/td\u003e\n\u003ctd\u003eTO-92 (3-pin)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eContactless DC current sensor (sensing magnetic flux around a wire)\u003c\/li\u003e\n  \u003cli\u003eProximity switch triggered by a magnet\u003c\/li\u003e\n  \u003cli\u003eRotary or linear position encoder with a magnet array\u003c\/li\u003e\n  \u003cli\u003eMagnetic field strength logger for experiments\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThe SS49E runs on 5V logic and outputs up to 5V, so it works directly with 5V Arduino boards (Uno, Mega). For 3.3V systems like ESP32 or Raspberry Pi Pico, use a voltage divider or logic-level converter on the output pin to avoid ADC damage. Common pairings include op‑amp buffers for weak fields and comparator circuits for threshold‐based switching.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003ePin 1 is supply (Vcc), pin 2 ground, pin 3 analog output. Current consumption is around 8 mA. Connect the output directly to an analog input – no pull‑up needed. Keep sensor leads short to avoid noise; a 0.1 µF decoupling capacitor between Vcc and ground near the sensor is recommended.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino?\u003c\/summary\u003e\u003cp\u003eYes, directly with 5V Arduino boards. Connect Vcc to 5V, GND to GND, and output to an analog pin like A0. Use analogRead() to get a value proportional to the magnetic field. For 3.3V Arduinos, a level shifter on the output is required.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhat voltage does it output when no magnet is near?\u003c\/summary\u003e\u003cp\u003eThe quiescent output is half the supply voltage – typically 2.5 V with a 5 V supply. A south pole field increases the voltage above 2.5 V, a north pole decreases it below 2.5 V.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan it work with a 3.3V supply?\u003c\/summary\u003e\u003cp\u003eNo, the SS49E is designed for a 4.5 V–5.5 V supply. Operating it from 3.3 V may result in unstable or incorrect output. Use a separate 5 V rail and level-shift the output for 3.3 V microcontrollers.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
