3500 Series/Low Thermal EMF Reed Relays Low Thermal EMF Reed Relays The 3500 Series is ideally suited to the needs of Instrumentation, Data Acquisition and Process Control. The specification tables allow you to select the appropriate relay for your particular application. Recommended for use in high accuracy DVM’s, Multiplexers and Digital or Analog Multipoint Recorders. If your requirements differ from the selection options, please consult Coto’s Factory to discuss a custom reed relay. 3500 Series Features Low Thermal EMF: < 10 µV through < 0.5 µV with 50 nV stability Patented Low Thermal Design. U.S. Patent #4,084,142 Low power coils to ensure low thermal EMF High Insulation Resistance - 1012 Ω Control/Signal isolation of 1500 VDC High reliability, hermetically sealed contacts Form A, Dry or Hg Wet contacts. High Dielectric Strength Epoxy coated steel shell provides magnetic shielding (For Model #’s 3501 & 3540) (For Model #’s 3502, 3520, 3541) Bottom View Dimensions in Inches (Millimeters) 14 COTO TECHNOLOGY (USA) Tel: (401) 943-2686 / Fax (401) 942-0920 6 (Europe) Tel: +31-45-5439343 / Fax +31-45-5427216 3500 Series/Low Thermal EMF 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 2 Consult factory for life expectancy at other switching loads. Models 3501 and 3540, optional electrostatic shield is tied to pin #5. Models 3502, 3520 and 3541, optional electrostatic shield is tied to pin #13. 3 Model 3520 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. 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 6 E-mail: sales@cotorelay.com For Most Recent Data, Consult the Coto Technology Website: www.cotorelay.com 15
