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 u Very small (0.20 in 2), high reliability reed relays u High Insulation Resistance - 1012Ω offered on 2904 u High speed switching compared to electromechanical relays u Hermetically sealed contacts for long life u Epoxy coated steel shell provides magnetic shielding u Optional Electrostatic Shield for reducing capacitive coupling u Optional Coaxial Shield for 50Ω impedance and switching of fast rise time digital pulses u RoHS compliant (except for 2920) DIMENSIONS in Inches (Millimeters) .250 (6.35) .820 (20.82) .280 (7.11) .500 (12.7) .125 (3.18) .700 (17.78) 1 2 3 4 8 7 6 5 .020 (0.51) .100 (2.54) .022 Dia. pins (0.56) Bottom View Ordering Information Part Number Model Number 2904 2911 2920 29XX-XX-XX1 Shielding Options2 0=No Shield 1=Electrostatic Shield 2=Co-axial Shield Coil Voltage 05=5 volts 12=12 volts Coil Options 1=Use for Model #2920 (5 & 12 volt coil) 3=Use for Model #2904 (12 volt coil) and for Model #2911 (5 & 12 volt coil) 4=Use for Model #2904 (5 volt coil) 07082013 tel: (401) 943.2686 | fax: (401) 942.0920 MODEL NUMBER Parameters Test Conditions Units 29042 29112 29202,3 1 Form A 1 Form C 1Form A Hg Wetted COIL SPECS.
