Product introduction

Reed relays persists as a compact and reliable digital components that play a pivotal role in various industries and technologies, offering efficient and precise switching capabilities. These relays consist of a hermetically sealed glass tube containing two flexible metal reeds positioned closely together. The operation of reed relays involves the interaction of these reeds, providing a dependable means of controlling electrical currents in diverse applications. Reed relays consist of essential components such as the reed switch, the coil and the contact terminals. The reed switch is the core element, composed of two metal reeds within a sealed glass envelope. These reeds are magnetically responsive, moving towards each other when exposed to a magnetic field and making contact to complete an power circuit. The coil which is wound around the reed switch, generates the magnetic field.

Advantages
  • Fast Switching : Reed relays can switch at high speeds, making them suitable for applications requiring quick response times.
  • Low Contact Resistance : The contacts in reed relays exhibit low contact resistance, ensuring minimal signal loss.
  • Long Life Span : The absence of moving parts in the switching mechanism contributes to a long operational life in demanding environments.
  • Compact Size : The compact design of the relays allows them to be used in space constrained applications.
  • Low Power Consumption : Reed relays require minimal power to operate, making them energy efficient.
  • High Insulation Resistance : The sealed glass envelope provides excellent insulation between contacts, reducing leakage and improving reliability.
