Not only can you access amazing prices when you buy direct, but at you have access to a wide range of sellers, all in one place. Have a look today and see how much easier it is to buy a relay sensor switch directly from a wholesaler or manufacturer. Our photoelectric sensors satisfy applications found in many industries. This technology is an ideal alternative to inductive proximity sensors when you require long sensing distances or when the item you want to sense is non-metal. In addition to the relay switches themselves, you'll also find essential accessories such as relay sensor switch clips. Photoelectric sensors use a beam of light to detect the presence or absence of an object. As well as specific options, you can also find general purpose relays listed at. Whether you need a small, large or even slim relay switch, you'll find exactly what you need here. They are most commonly needed in circuits where the amperage rises significantly at certain points.Īvailable in a variety of types, including time delay, latching, solid state, sequential and automotive, as well as 4 pin, 5 pin, 6 pin and 8 pin varieties. These clever devices are used extensively in appliances, cars and other vehicles and are absolutely essential for the effective working of these machines. This conversion is carried out through electromagnetism. The purpose of a relay sensor switch is to convert a small electrical input into a high output. These essential electrical accessories have an important job to do. Used in Automobiles electronics for controlling indicators glass motors etc.There are numerous reasons to seek wholesale prices on your relay sensor switch order, especially for producers of circuits who use large quantities of relays, and for retailers or small wholesalers who sell to the automotive or electrical engineering industries.Used in safety circuits to disconnect the load from supply in event of failure.To Control (On/Off) Heavy loads at a pre-determined time/condition.For Home Automation projects to switch AC loads.If connected to NO the load remains disconnected before trigger and if connected to NC the load remains connected before trigger. As shown one end of the load can be connected to the Common pin and the other end is either connected to NO or NC. The purpose of the diode is to protect the switch from high voltage spike that can produced by the relay coil. You can also notice a diode connected across the coil of the relay, this diode is called the Fly back Diode. This switch can be anything from a small transistor to a microcontroller or a microprocessor which can perform switching operating. Since the relay has 5V trigger voltage we have used a +5V DC supply to one end of the coil and the other end to ground through a switch. The above circuit shows a bare-minimum concept for a relay to operate. Make sure the load you are using falls into this range. The other parameter is your Load Voltage & Current, this is the amount of voltage or current that the NC,NO or Common terminal of the relay could withstand, in our case for DC it is maximum of 30V and 10A. Our relay here has 5V trigger voltage, but you can also find relays of values 3V, 6V and even 12V so select one based on the available voltage in your project. Once is the Trigger Voltage, this is the voltage required to turn on the relay that is to change the contact from Common->NC to Common->NO.

If connected to NO the load remains disconnected before trigger The other end of the load is either connected to NO or NC. If connected to NC the load remains connected before trigger Used to trigger(On/Off) the Relay, Normally one end is connected to 5V and the other end to groundĬommon is connected to one End of the Load that is to be controlled
