2900 Series Reed Relays
2900 Series Reed Relays
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
2900 Series Features
Very small (0.20 in ), high reliability reed relays
High Insulation Resistance - 10
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

Dot stamped on top of relay refers to pin #1 location
Grid = .1"x.1" (2.54mm x 2.54mm)
Environmental Ratings:
Storage Temp: -35°C to +100°C;
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
Consult factory for life expectancy at other switching loads.
Model 2904, 2911 and 2920, pin #7 is tied to optional electrostatic shield, pins #6 & #7 are tied to optional coaxial shield.
Model 2920 has Hg wet contacts - position sensitive, must
be mounted within 30° of vertical plane. See schematic.
Hg Content per capsule: Form A, 0.04 grams.
Consists of 56V Zener diode and 1N4148 diode in series,
connected in parallel with coil.
