Varenr:
H42713
EAN:
5705412427135
Hall-effekt sensor registrerer magnetisme. I sin enkleste form fungerer sensoren som en analog transducer, der direkte returnerer en spænding. Med et kendt magnetfelt kan dets afstand fra Hall-pladen bestemmes. Ved hjælp af grupper af sensorer kan magnetens relative placering udledes.
Elektricitet, der føres gennem en leder, producerer et magnetfelt, der varierer med strømmen, og en Hall-sensor kan bruges til at måle strømmen uden at afbryde kredsløbet. Typisk er sensoren integreret med en viklet kerne eller permanent magnet, der omgiver lederen, der skal måles. Ofte er en Hall-sensor kombineret med kredsløb, der gør det muligt for enheden at fungere i en digital (tænd/sluk) tilstand og kan kaldes en switch i denne konfiguration.
Tekniske detaljer:
- Producent (varemærke): ALLEGRO MICROSYSTEMS
- Type sensor: Hall, non-latching
- Hus: SIP3 (TO92S)
- Måleområde: 50...330Gs
- Operationel forsyningsspænding (Vcc): 4,5...24V
- Maks. forsyningsspænding: 28V
- Operationel temperatur: -40...85°C
- Udgangsstrøm: 25mA
- Montering: Printhul
Ben konfiguration:
- 1: +5V (Vcc), Til strømforsyning af hall sensor, typisk +5V
- 2: Ground. Tilslut til kredsløbets jord
- 3: Digital output. output går lavt, hvis magnet detekteres. Udgangsspænding er lig med driftsspænding.
Tips:
- Brug en pullup modstand til at holde output høj (f.eks. 10Kohm) når ingen magnet er detekteret.
- Brug en 0,1uF kondensator til at filtrere eventuel støj, der måtte være forbundet med den digitale udgang.
Også kendt som: A3144E, A3144EUA, OH3144E.
Hall effect sensor registers magnetism. In its simplest form, the sensor operates as an analog transducer, directly returning a voltage. With a known magnetic field, its distance from the Hall plate can be determined. Using groups of sensors, the relative position of the magnet can be deduced.
Electricity carried through a conductor will produce a magnetic field that varies with current, and a Hall sensor can be used to measure the current without interrupting the circuit. Typically, the sensor is integrated with a wound core or permanent magnet that surrounds the conductor to be measured.
Frequently, a Hall sensor is combined with circuitry that allows the device to act in a digital (on/off) mode, and may be called a switch in this configuration.

- Case: SIP3
- Measuring range: 50...330Gs
- Operating supply voltage (Vcc): 4,5...24V
- Max. supply voltage: 28V
- Operating temperature: -40...85°C
- Output current: 25mA
- Mounting: PCB
Pin konfiguration:
- 1: +5V (Vcc), Used to power the hall sensor, typically +5V is used
- 2: Ground. Connect to the ground of the circuit
- 3: Digital Output. This pin goes high, if magnet detected. Output voltage is equal to Operating voltage.
Tips:
- Connect a pullup resistor to keep output high (eg. 10Kohm) when no magnet is detected.
- Connect en 0,1uF capacitor to filter any noice that might be coupled with the digital output.
