Littelfuse Introduces Expanded Reed Relays Portfolio

Littelfuse has launched an expanded reed relay product portfolio that extends voltage capabilities to include AC ratings, supports AC or DC loads up to 300 Vdc, and provides input/output isolation voltage 2500 VRMS.

These miniature reed relays are available in single In-line (SIL) and dual-in-line (DIL) packages.

“The expansion of the Littelfuse reed relay portfolio is a reflection of our commitment to meeting our customers’ needs through technology and product development,” said Boris Golubovic, Vice President, Marketing and Strategy at Littelfuse. “Reed relays are uniquely suited for a wide range of applications, including process automation, and rapidly growing building technologies segment.”             

Typical applications for the reed relays include position and speed sensing in a broad array of markets:

  • Security systems
  • Fire and safety
  • Instrumentation
  • Telecom
  • Automatic test equipment (ATE)
  • Process control systems

The new reed relays offer these key benefits:

  • Capable of switching speeds up to 1 kHz and billions of operations.
  • Hermetically sealed switch contacts are unaffected by and do not affect their external environment.
  • Lower power coil consumption than competing electromechanical devices.
  • Very low circuit board space requirement due to miniature DIL and SIL packages.
  • No leakage in the off state, making them an ideal choice for battery-powered devices.

A reed relay combines a reed switch with a coil into one package to serve as a smaller, more power-efficient alternative to other types of relays. In comparison to solid-state relays (SSRs), reed relays provide no leakage current and higher robustness against transient spikes.

Reed relays also have a much longer life, smaller size, higher switching speeds, and lower power consumption than electromechanical relay switches.

Reed relays are used for switching of loads with up to 2500 V isolation between the low-voltage control signal and load circuit.

Reed relays come in a hermitically sealed miniature package and offer full galvanic (zero leakage current) load disconnect that provides the high reliability needed in harsh environment applications to switch AC/DC signals and loads.
