Electrical Ratings
Series 94H and 94R
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
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.
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. Internal O-ring: Rubber BUNA-N
Soldering Information
Soldering Temperature: 260 C maximum. Cleaning: Acceptable solutions include 1-1-1 Trichlorenthane, Freon (TF, TE, or TMS), Isopropyl Alcohol and detergent (140F maximum). Solutions which are not recommended include Acetone, Methylene Chloride, and Freon TMC.
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 E. 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.
