Reed Relay Circuit Diagram
Reed contact protection circuits it is assumed that the ideal reed switch load is a resistive load but it is almost impossible to reduce any load to purely resistive.
Reed relay circuit diagram. A reed relay is a type of relay that uses an electromagnet to control one or more reed switches the contacts are of magnetic material and the electromagnet acts directly on them without requiring an armature to move them. They require a much lower level of power to actuate them than other traditional types of relay and as a result they find many uses in various forms of electronic circuits. Pickering electronics explains what a reed relay is and how it is manufactured. Sealed in a long narrow glass tube the contacts are protected from corrosion the glass envelope may contain multiple reed switches or multiple reed switches can be inserted.
In this circuit we will simply demonstrate the use of a reed switch by placing it in a very basic circuit. Some circuits would be illegal to operate in most countries and others are dangerous to construct and should not be attempted by the inexperienced. Simply put it is a magnetic switch. Electronic circuit schematics note that all these links are external and we cannot provide support on the circuits or offer any guarantees to their accuracy.
Need help for small circuit run timed reed relay. We will connect it to an led just to demonstrate how a reed switch works. They have faster switching speed compared to the electromechanical ones but their switching current and voltage is lower mainly because of its contacts thickness. How to build a reed switch circuit.
The reed relay consists of a switch with magnetic contacts that move under the influence of an external magnetic or the induced field from its solenoid. Reed relays contain a reed switch a coil for creating a magnetic field an optional diode for handling back emf. This high voltage reed relay series features an insulation resistance 5 x 10 12 ω and utilizes minimum pcb area at only 50 compared to our dip and dil reed relay series. Reed relays are small and fast acting.
There are normally open reed switches and normally closed reed switches. There are 2 basic types of reed switches. Using a window sensor reed switch to control audio system speakers using a relay. The shv reed relay is a single in line and high voltage relay or instrumentation grade reed relay supplied in a molded housing capable of switching up to 1kvdc and breakdown voltage of 4kvdc.
Change direction of 9v dc motor rotation using reed switches and relay s 120v lighting power pack 24v low voltage switching controlled by reed relay. Therefore when a reed switch is to be connected to an inductive load or a load where inrush current flows such as a capacitive load or a lamp load contact protection circuits are required in order to increase the life of.
