CODICO offers signal and high-voltage reed relays! CODICO offers a broad range of reed relays and contacts. In addition, we are pleased to provide custom designs and selections, even complete sensor units with pre-assembled cables if so desired! Reed relays are extremely reliable and ideally suited for especially low switching loads, regardless whether a high or low switching rate is used (even as low as once every 10 years). And, compared to similarly dimensioned conventional electromagnetic relays, reed relays can be designed for very high switching voltages (up to 10kV). They are also available in DIL and SMD packages, two commonly used formats for PCB mounting in the microelectronics industry.

 

General technical information on reed relays: Even today, reed relays – so named because the contacts are in the form of metal reeds – still occupy a significant role in the field of relay technology. Thanks in particular to polarized relay technology, reed relays have enjoyed an impressive development history. The first changeover reed relays had a closed glass tube with one non-magnetic and two ferromagnetic reed contacts fused in inside. Excitation of the coil caused the two ferromagnetic contacts to close. However, the discharge of silicate vapor from the glass during the fusing-in process proved to be disadvantageous for contact resistance. Modern reed relays have since been fitted with additional design functionality to improve contact strength. Today’s relays are filled with an inert gas and come embedded in a synthetic resin. In addition, the reed contacts are bifurcated to create a reliable double-make contact. The permanent magnet is arranged such that its flux is superimposed on the flux of the excitation coil.

 

Thanks to their construction, reed relay contacts are protected from corrosion and oxygen. Not only does this make them extremely reliable, but they are also especially well suited for use with low switching power – regardless whether the relays are activated frequently or very rarely (e.g., only once every 10 years). Unlike conventional electromagnetic relays with similar dimensions, reed relays can be designed for very high switching voltages (up to 10kV) by increasing the interior pressure of the filling gas. Reed relays are also available in DIL and SMD packages, two commonly used formats for PCB mounting within the microelectronics industry.
