Reed Switch / Magnetic Sensor

$16.2 $29.32
Reed SwitchA reed switch is an electromagnetic switch used to control the flow of electricity in a circuit. The switch looks like a small glass capsule with electrical leads poking out of each end. When a magnetic field is moved in the direction of the switch, the reeds get magnetized and move together or apart.It features incredibly high reliability for a mechanical switch, and they’re able to function for billions of cycles before failing. Additionally, because of their sealed construction, they can operate in explosive environments where a spark could potentially have disastrous results.Features –Glass Length: 14mmGlass Diameter: 2mmTotal Length: 45mmMax.

They consist of two or more ferrous reeds enclosed in a tiny glass tube-like envelope. When a magnetic field is moved in the direction of the switch, the reeds become magnetized and move together or apart.How Does a Reed Switch Work?Two ferromagnetic blades only a few microns apart make up the switching mechanism. The two blades pull together when a magnet approaches these blades. The blades close the normally open (NO) contacts when they come into contact, allowing electricity to flow. Additionally, some reed switches have a non-ferromagnetic contact that creates a normally closed (NC) output. The switching contact will become disconnected and pull away from an approaching magnet.Several metals, including tungsten and rhodium, are used to make contacts. Some even employ mercury, which needs to be kept in the correct orientation to switch properly. The contacts are sealed by a glass envelope under one atmosphere of internal pressure and filled with inert gas, typically nitrogen.What is the usage of Reed Switch?Electronics ProjectsMedical DevicesSecurity Devices etc.How is a reed switch activated?Although it can be activated by placing it inside an electrical coil, many reed switches and reed sensors are used for proximity sensing and are activated by a magnet. As the magnet is brought into the proximity of the reed sensor/switch, the device activates.What is the price of Reed Switch in Bangladesh?Please check our prices of reed switch at the top of the page. একটি রিড সুইচ হল একটি ইলেক্ট্রোম্যাগনেটিক সুইচ যা সার্কিটে বিদ্যুতের প্রবাহ নিয়ন্ত্রণ করতে ব্যবহৃত হয়। সুইচটি দেখতে একটি ছোট কাচের ক্যাপসুলের মতো দেখায় যার প্রতিটি প্রান্ত থেকে বৈদ্যুতিক সীসা বেরিয়ে আসছে। যখন একটি চৌম্বক ক্ষেত্র সুইচের দিকে সরানো হয়, তখন নলগুলি চুম্বকীয় হয়ে যায় এবং একসাথে বা দূরে সরে যায়। রিড সুইচগুলি একটি যান্ত্রিক সুইচের জন্য অবিশ্বাস্যভাবে উচ্চ নির্ভরযোগ্যতা বৈশিষ্ট্যযুক্ত, এবং তারা ব্যর্থ হওয়ার আগে কোটি কোটি চক্রের জন্য কাজ করতে সক্ষম। উপরন্তু, তাদের সিল করা নির্মাণের কারণে, তারা বিস্ফোরক পরিবেশে কাজ করতে পারে যেখানে একটি স্পার্ক সম্ভাব্য বিপর্যয়কর ফলাফল হতে পারে।Keep an eye on our website to avail the –Reed Switch best price in Bangladesh (BD)
