Reed Relays
2900 Series Reed Relays with Option of 1-Form A or 1-Form C
Ideally suited to the needs of Automated Test Equipment and RF requirements. The specification tables allow you to select the appropriate relay for your particular application. Slightly larger than the 2200 Series; these relays provide maximum versatility with options such as a Form C with electrostatic or co-axial shielding. If your requirements differ, please consult your local representative or Coto’s Factory.
- Very small (0.20 in2), high reliability reed relays
- High Insulation Resistance - 1012Ω offered on 2904
- High speed switching compared to electromechanical relays
- Hermetically sealed contacts for long life
- Epoxy coated steel shell provides magnetic shielding
- Optional Electrostatic Shield for reducing capacitive coupling
- Optional Coaxial Shield for 50Ω impedance and switching of fast rise time digital pulses
- RoHS compliant (except for 2920)
Applications
- Automated Test Equipment
