מתג מגנטי
תיאור
המתג המגנטי מורכב ממוליכי מגע שטוחים, אשר אטומים הרמטית בתוך צינור זכוכית מלא בגז אינרטי (מגע ריד). כאשר מקרבים מגנט קבוע, קצות מוליכי המגע החופפים נמשכים זה לזה ומתאחדים באמצעות קפיץ לכדי מגע. עם הסרת המגנט הקבוע, מוליכי המגע מתמגנטים-בחזרה מיד וחוזרים למצבם הרגיל.
המרווח האווירי בין קצות מוליכי המגע הוא רק 0.2 ... 0.3 mm ולמוליכי המגע עצמם מסת ההזזה וכוח הקפיץ שלהם קטנים מאוד. לכן המתג המגנטי מיתוג כמעט ללא אינרציה, וניתן להתייחס אליו כאל "רכיב כמעט-אלקטרוני".

מתגים מגנטיים אלה, חסכוניים במיוחד, קלים מאוד להתקנה, מתאימים באופן מצוין לאוטומציה של תהליכים וכן כאינדיקטורי מיקום עבור מחליקים, דפנות ומסתמים.
האמינות של מתגים קומפקטיים אלה מובטחת באמצעות אורך חיי השירות החשמליים שלהם. מאחר שהמתגים המגנטיים מורכבים ברובם מרכיב בודד בלבד, הם בטוחים במיוחד בתפעול.
תכונות מיוחדות
- מפסקים מגנטיים פועלים כהלכה בתנאי סביבה קיצוניים, למשל לכלוך, לחות, גזים, אבק, שבבים וכו'
- נקודת מיתוג יציבה, דיוק נקודת מיתוג ניתן לשחזור 0.01 mm
- מגע Reed ניתן להפעלה ממספר כיוונים
- ניתן להתקנה בכל כיוון
- ניתן להפעלה במצב ללא מתח, גרסאות ביסטביליות יכולות לשמור אותות ומתאימות במיוחד לאורכי מהלך ארוכים במיוחד
שאלות ותשובות
מהו טווח הטמפרטורות המותר לפעולה?
המתג פועל בטמפרטורות סביבה ותהליך של -10 … +80 °C.
מהי דיוק נקודת המיתוג?
נקודת המיתוג יציבה וניתנת לחזרה בדיוק של 0.01 mm.
אילו אפשרויות חיבור מכני קיימות?
הברגות M10 x 1, M12 x 1 או M18 x 1.5, וכן גרסה ללא הברגה עם גוף גלילי.
מהם אותות הפלט הזמינים?
מגע יבש מסוג קנה (reed): נורמלית פתוח, נורמלית סגור, ממיר (change-over), וכן גרסאות ביסטביליות השומרות אות.
האם המתג מתאים לסביבות מזוהמות?
כן — המתג פועל כהלכה גם בהשפעות סביבה קיצוניות כגון לכלוך, לחות, גזים, אבק ושבבים, עם דרגת הגנה IP65.
מה מבדיל את הגרסה הביסטבילית?
הגרסה הביסטבילית שומרת את האות גם ללא הפעלה מתמשכת, ולכן מתאימה במיוחד לאורכי מהלך ארוכים במיוחד.
מאילו חומרים עשויים חלקי המתג?
פליז, פלדת אל-חלד, פוליאמיד מחוזק בסיבי זכוכית ואלומיניום, בהתאם לדגם.
כיצד מבוצע החיבור החשמלי?
באמצעות כבל או מחבר, בהתאם לדגם.
