HE722A1200 LITTELFUSE Reed Relay

Review LITTELFUSE Reed Relays Relay

The Littelfuse HE722A1200 Reed Relays are a dependable and compact solution for various switching applications.These relays are available in packs of 50, offering an economical choice for large-scale projects. With a switching capacity of up to 1200V AC and 5A, these relays can handle heavy loads and are suitable for applications requiring electrical isolation between circuits.

The HE722A1200 Reed Relays employ a contactless operating principle, utilizing magnetic fields and Hall effect sensors to switch contacts. This mechanism results in a contact life of over 100 million cycles, ensuring a long operational life and reliable performance.

The relays feature a compact size, measuring just 16mm x 15mm x 6mm and weighing a mere 2.3 grams each, making them suitable for applications with limited space constraints. They are also RoHS compliant, guaranteeing compliance with the Restriction of Hazardous Substances Directive.

These relays offer low operating power, consuming only 1.5mA during the coil ON state and 10mA during the coil OFF state. They also have a negligible coil inductance of 0.27mH, minimizing electrical noise and making them a preferred choice for applications requiring fast switching times.

The HE722A1200 Reed Relays boast a wide operating temperature range of -40 C to 85 C, ensuring that they can perform effectively in various environments. They are well-shielded to prevent electromagnetic interference and can be operated in voltages as low as 5V.

These relays are available with either normally open (NO) or normally closed (NC) contacts, catering to various switching requirements. With their excellent reliability, fast switching, and compact size, Littelfuse HE722A1200 Reed Relays are an ideal choice for applications in motor control, lighting systems, telecom, industrial automation, and more.

Littelfuse HE722A1200 reed relays are commonly used in various applications due to their compact size, reliability, and fast switching abilities. Below are some pros and cons of using these relays:

1. Compact Size: The HE722A1200 relays are small in size, making them ideal for applications where space is limited. The size also makes them suitable for use in mass-produced products.

2. Fast Switching: These relays have a contact bounce time of less than 50 nanoseconds, making them suitable for use in applications where fast switching is required.

3. Long Operating Life: The contacts in these relays are hermetically sealed, which prevents them from being affected by moisture, dust, and other environmental factors. This results in a long operating life.

4. Low Power Consumption: He722A1200 relays have a low power consumption, making them suitable for use in battery-powered applications.

5. High Operating Temperature: These relays can operate in temperatures ranging from -40 C to 85 C, making them suitable for use in various industrial applications.

1. Limited Current Capacity: These relays are not suitable for applications that require large current capacities. They have a maximum switching capacity of 5 amps and 30V AC/DC.

2. Contact Resistance: The HE722A1200 relays have a contact resistance that can change over time, which may affect their switching performance.

3. Non-Latching: These relays are non-latching, meaning they require a continuous voltage to maintain the contact closure.

4. Fragile: Reed relays are delicate devices and can be damaged if mishandled or subjected to vibrations or shock.

The Littelfuse HE722A1200 reed relays are an excellent choice for applications that require fast switching, compact size, and a long operating life. However, they are not suitable for applications that require large current capacities or high shock and vibration resistance. The contact resistance and non-latching nature of these relays may also pose challenges in some applications.

If you're looking for a compact, fast-switching relay for applications that don't require large current capacities, then the Littelfuse HE722A1200 reed relays are an excellent choice. However, if you need a relay with higher current capacities, shock and vibration resistance, or latching function, then you should consider other types of relays such as solid-state relays or electromechanical relays. It is essential to evaluate the specific requirements of your application and choose a relay that best fits those needs.
