2900 Series/Microminiature Reed Relays
ICROMINIATURE REED RELAYS
Ideally suited needs Automated Test Equipment requirements. specification tables allow select appropriate relay your particular application. Slightly larger than 2200 Series; these relays provide maximum versatility with options such electrostatic coaxial shielding. your requirements differ, please consult your local representative Coto's Factory.
2900 SERIES FEATURES
Very small (0.20 in2), high reliability reed relays. High Insulation Resistance offered some models. High speed switching compared electromechanical relays. Hermetically sealed contacts long life. Epoxy coated steel shell provides magnetic shielding. Optional Electrostatic Shield reducing capacitive coupling. Optional Coaxial Shield impedance switching fast rise time digital pulses.
