Reed relays are some of the oldest, but still most popular, and reliable electromechanical switches in use today. HE751A1200 is a type of reed relay that is commonly used in a variety of fields, including medical applications, industrial and automotive applications, and other types of electronic test and measurement. This is because the HE751A1200 is a high quality reed relay with low switching power, high switching performance, and good resistance to environmental extremes.

The HE751A1200 is constructed from a closed tube and contains a movable piece of reed material which is magnetically activated to open or close a circuit. Magnetic force generated from an external coil or solenoid is used to move the reed material in the reed relay. The reed material, usually composed of corrosion-resistant stainless steel, reacts to a small current that is produced from the externally-generated magnetic field in order to open or close the circuit. A vacuum chamber is used to keep the atmosphere inside the reed relay debris-free which in turn provides improved reliability in the performance of the device.

The HE751A1200 offers a fast response time of less than ten milliseconds and can easily switch AC or DC currents up to 12 amps at a switching voltage of 450 volts. It also has high insulation resistance of greater than one gigohm and long life expectancy of 100,000 operations. These features make the HE751A1200 ideal for applications requiring low level switching and high noise immunity. Additionally, the device is designed to provide a low on-resistance and higher contact capacity.

The HE751A1200 is used in a variety of applications due to its low switching power and resistance to environmental extremes. In medical instrumentation, it is used to control the switching on and off of electrical equipment to promote accurate data collection. It is also used in industrial and automotive applications to control electrical and safety devices in order to reduce the risk of electrocution. Additionally, the HE751A1200 is often used in electronic test and measurement systems for signal control and contact closure.

In conclusion, the HE751A1200 is a versatile reed relay with features that make it suited for a variety of applications. The reed relay is constructed from a sealed tube, contains a movable piece of reed material, and is activated by an external coil or solenoid that generates a magnetic field. The HE751A1200 has a short response time of less than ten milliseconds, good resistance to environmental extremes, high insulation resistance, and a long life expectancy of 100,000 operations. It can be used in a variety of applications, including medical instrumentation, industrial and automotive applications, and electronic test and measurement.
