Reed relays are an electromechanical switching device that transfers a signal when an electric current is applied to the control coil. The KT12-1A-40L-SMD reed relay is a high voltage reed relay designed to allow higher current to pass through the contact points. By designing the KT12-1A-40L-SMD with a higher voltage rating, it can be used to control larger power loads at higher frequencies.

The KT12-1A-40L-SMD reed relay has a fixed normally-closed contact that is activated when a small current is applied to an internal coil. When the current is no longer applied, the contact reverts back to the normally-closed position. The system integrates a diode to protect the reed switch from reverse current and prevent the leakage of certain frequencies.

The contact form of the KT12-1A-40L-SMD is a 1A/40A contact, meaning that the system has a maximum rating of 1 amp when in the normally-closed state and 40 amps when the coil is energized. The contact rating is determined by the type and size of the coil and the contact material used in the application. The coil is rated at 12 volts DC and requires less than 100mA of current to energize it. This provides ample power to operate larger loads.

The operating temperature range for the KT12-1A-40L-SMD is -40 to 85C, with the maximum life expectancy of 10 million cycles. The contact material is copper alloy and is vibration and shock resistant, making the KT12-1A-40L-SMD suitable for use in harsh environments. The contact gap of the reed switch is also adjustable, allowing for precise control over the current flow.

The main application fields of the KT12-1A-40L-SMD include automotive, consumer electronics, computers, telecommunications, power control, automotive, and industrial applications. It is suitable for use in systems where high current output is required, such as electric motor control or industrial pumps systems. The reed relay can be used for low voltage detection, as it can detect even very small current levels and provide reliable switching at higher currents.

The KT12-1A-40L-SMD reed relay is an extremely reliable and cost effective electric switching device. By combining the features of a diode, adjustable contact gap, and shock and vibration resistant material, it provides a reliable and easily controlled switching option. The operating temperature range of the reed switch makes it suitable for use in a variety of applications, allowing it to be utilised for low voltage detection and switching large power loads. The wide application field of the reed relay makes it a great choice for many different projects.
