High Density Matrix Relays

Our high density matrix reed relays were designed specifically for large and closely stacked switching matrices. Switch matrices are typically used in functional PCB test systems. Internal magnetic shielding eliminates magnetic coupling effects between reed relays stacked very close together. The CRF series is our smallest and most versatile instrument grade reed relay series. Even more the CRF can carry RF signals from DC up to 7 GHz. As well as fast digital pulses with skew rates <20 picoseconds in a 50 ohm impedance environment. Furthermore the CRF series is our lowest profile reed relay measuring only 3.6mm high. The CRF series high density reed relays feature a rugged ceramic package that has excellent low thermal capabilities. Low thermal offset voltages. Less than 1 microvolt in fact. Finally the CRF series can operate reliably over a wide temperature range. Above all this relay series will perform billions of high speed signal switching operations in an economical way.
