Ideally suited to the needs of Automated Test Equipment and RF
requirements. The specification tables allow you to select the appropri-
ate relay for your particular application. Slightly larger than the 2200
Series; these relays provide maximum versatility with options such as
electrostatic and coaxial 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 - 1012 Ω offered on some models.
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 50 Ω impedance and switching of fast
rise time digital pulses.

1Consult factory for life expectancy at other switching loads.
2Model 2904, 2911 and 2920, pin #7 is tied to optional electrostatic
shield, pins #6 & #7 are tied to optional coaxial shield.
3Model 2920 has Hg wet contacts - position sensitive, must
be mounted within 30° of vertical plane. See schematic.
4Consist of 20V Zener-Diode and 1N4002 diode in series,
connected in parallel with coil.

Operating Temp: 20°C to 85°C
Solder Temp: 270°C max; 10 sec. max
The operate and release voltage and the coil
resistance are specified at 25°C. These values
vary by approximately 0.4%/°C as the ambient
temperature varies.
Vibration: 20 G’s to 2000 Hz; Shock: 50 G’s
