FEATURES
10,000 Cycles of Operation Gold-Plated Contacts Sealed Contact System Right Angle Mount Octal, BCD & Hexadecimal Codes Standard or Complement RoHS Compliant SPECIFICATIONS: Series 94H and 94R Electrical Ratings Make-and-break Current Rating: 30 mA at 30 Vdc for 10,000 cycles of operation. Carrying Current Rating: 100 mA at 50 Vdc Contact Resistance: 50 mohms maximum initially (measured at 10 mA, 50 mVdc). 150 mohms maximum after life. Insulation Resistance:(measured at 100 Vdc across open switch contacts) Initial: 5000 Mohms minimum. After Life: 1000 Mohms minimum. Dielectric Strength: (measured across open switch contacts) Initial: 500 Vac RMS minimum. After Life: 250 Vac RMS Mechanical Ratings Mechanical Life: 10,000 cycles of operation. One cycle is a rotation through all positions and a complete return through all positions. Mechanical Shock: 1000g's, 0.5 mS, half sine per MIL-STD-202F, Method 213, Test Condition Vibration Resistance: 10-2000 Hz at 15G or 0.060" double amplitude per MIL-STD-202F, Method 204, Test Condition B. Operational Torque: 2 to 6 inch-ounces initially and 1.2 inch-ounces minimum after life. Environmental Ratings Operating Temperature Range: -40° to +85°C. Storage Temperature Range: -40° to +85°C. Moisture Resistance: 240 hours with temperature cycling and polarization. Passes insulation resistance and dielectric strength per MIL-STD-202F, Method 106 following exposure. Materials and Finishes Rotor and Switch Body: Plastic (UL94V-O) Contact Material: Copper alloy plated. 30 microinches minimum gold over 50 microinches minimum nickel. Shorting Member: Copper alloy plated. 30 microinches minimum gold over 50 microinches minimum nickel. Terminals: Copper alloy, matte tin plated over nickel barrier. CODE & TRUTH TABLES: Series 94H and 94RDIMENSIONS In inches (and millimeters) Unless otherwise indicated, tolerances are ± .010 (0,25) SWITCH POSITION CODE OUTPUT CODE OUTPUT 8 8412 A B C D E F 412 Standard Output Complement Output Dot indicates terminal to common connection. All switches are continuous rotation. Octal and Octal Complement outputs are 0 thru 7 positions. BCD and BCD Complement outputs are 0 thru 9 positions. Hexadecimal and Hexadecimal Complement outputs are 0 thru F positions. Standard codes have natural color rotors; complements have rotors in a contrasting color. .213 (5,41) .433 (11,00) .443 (11,25) .480 (12,19) .286 (7,26) 1.123 (28,52) .044 (1,12) DIA. .179 (4,55) .094 (2,93) .162 (4,11) .059 (1,50) .058 (1,47) DIA. .199 (5,05) .235 (5,97) C C PC board layout as viewed from the top of the switch Pin #1 Internal O-ring: Rubber BUNA-N Soldering Information Soldering Temperature: 260° C maximum.
