Magnetic sensors are integral components for many everyday technologies. They are used both industrially and commercially as switches in machines and electronic equipment, but are now also used in consumer applications due to their versatility and simple installation. The OMH3019S is a solid-state magnetic sensor designed to detect the presence or absence of a magnetic field. It is a compact, cost-effective switch suitable for a number of applications.

Application Field
The OMH3019S can be used in a variety of applications, including water pumps, fans, door and window openers, medical devices, security systems, and power switches. As a contacts-free switch, it can provide reliable, long-term operation with minimal maintenance. Its compact size makes it an ideal choice for hard-to-reach locations or when space is limited, such as in security panels or medical instrumentation.

Working Principle
The OMH3019S is a solid-state magnetic switch that utilizes an integrated Hall effect sensing element to detect changes in the magnetic field. When a magnetic field is present, the hall element produces an output voltage, which can then be used to activate a switch. When the magnetic field is no longer present, the switch is de-activated. This allows for the automation of turning on or off certain actuators in response to the presence of a magnetic field.

This solid-state switch offers improved accuracy and reliability due to its contacts-free operation. As with any magnetic switch, certain objects, such as large electrical motors or powerful magnets, can interfere with its functioning. However, the OMH3019S is designed to overlook such magnets and still provide reliable operation.

The OMH3019S is designed to work with DC voltages of up to 24V, while its contact-loading capability is up to 0.5A (at DC). The contact resistance is approximately 20mΩ, and the sensor also features LED technology for visual indication of its switching status. With a temperature range of -40oC to +85oC, the OMH3019S is well-suited to a variety of applications across a wide temperature range.

The OMH3019S is a versatile, solid-state magnetic switch, offering cost-saving and reliable operation in a wide variety of applications. Thanks to its intuitive design, strict quality control, and advanced technology, this switch is sure to provide more than satisfactory performance for many years to come.
