Why Omron Relays is Best Company in Production of Mechanical Components

Omron Electronic Components is the world’s leading supplier of technologically advanced electronic components. Omron’s product line includes general switches, snap-action switches, control switches, DIP/SIP switches, miniature switches, sub-miniature switches, thumbwheel switches, relays, connectors, optoelectronics, and sensors. Omron distributor in oman is the world’s leading supplier of relays. Omron offers an exceptional variety and technologically advanced relays for virtually any relay requirement.

Omron founder Kazuma Tateisi, a brilliant inventor and determined salesman, tried his hand at a knife-grinder and trouser press before launching Tateisi Electric Manufacturing Co. in 1933 based on a need by hospitals for faster X-ray timers. The three employee staffed factory grew into Omron Corporation, today a $4.5 billion global leader in sensing and control components with over 23,000 employees spread out across 35 countries. With a global reputation for unsurpassed quality and reliability in their switches and relays, Omron is now setting new standards worldwide.

Relay Switch Circuit

Omron relay muscat are electromechanical devices that use an electromagnet to operate a pair of movable contacts from an open position to a closed position.

The advantage of relays is that it takes a relatively small amount of power to operate the relay coil, but the relay itself can be used to control motors, heaters, lamps or AC circuits which themselves can draw a lot more electrical power.

The electro-mechanical relay is an output device (actuator) which come in a whole host of shapes, sizes and designs, and have many uses and applications in electronic circuits. But while electrical relays can be used to allow low power electronic or computer type circuits to switch relatively high currents or voltages both “ON” or “OFF”, some form of relay switch circuit is required to control it.

The design and types of relay switching circuits is huge, but many small electronic projects use transistors and MOSFETs as their main switching device as the transistor can provide fast DC switching (ON-OFF) control of the relay coil from a variety of input sources so here is a small collection of some of the more common ways of switching relays.

NPN Relay Switch Circuit

A typical relay switch circuit has the coil driven by a NPN transistor switch, TR1 as shown depending on the input voltage level. When the Base voltage of the transistor is zero (or negative), the transistor is cut-off and acts as an open switch. In this condition no Collector current flows and the omron relay muscat coil is de-energised because being current devices, if no current flows into the Base, then no current will flow through the relay coil.

If a large enough positive current is now driven into the Base to saturate the NPN transistor, the current flowing from Base to Emitter (B to E) controls the larger relay coil current flowing through the transistor from the Collector to Emitter.
