| 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 Factory. 2900 Series Features Very small (0.20 in2), high reliability reed relays High Insulation Resistance - 1012 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 impedance and switching of fast rise time digital pulses Dimensions in Inches (Millimeters) Bottom View 2 12 COTO TECHNOLOGY (USA) Tel: (401) 943-2686 / Fax (401) 942-0920 6 (Europe) Tel: +31-45-5439343 / Fax +31-45-5427216 2900 Series Reed Relays Top View: Dot stamped on top of relay refers to pin #1 location Grid = .1"x.1" (2.54mm x 2.54mm) Notes: 1 Environmental Ratings: Storage Temp: -35C to +100C; Operating Temp: -20C to +85C Solder Temp: 270C max; 10 sec. max The operate and release voltage and the coil resistance are specified at 25C. These values vary by approximately 0.4% / C as the ambient temperature varies. Vibration: 20 G's to 2000 Hz; Shock: 50 G's 6 E-mail: sales@cotorelay.com Consult factory for life expectancy at other switching loads. 2 Model 2904, 2911 and 2920, pin #7 is tied to optional electrostatic shield, pins #6 & #7 are tied to optional coaxial shield. 3 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. 4 Consists of 56V Zener diode and 1N4148 diode in series, connected in parallel with coil.
