Standard Keypads Series 82 Lightable Keyboards and Keypads FEATURES * 11/16" Between Button Centers * Long, Stroke, Wiping Contact * Lightable Modules * Choice of 5 Circuitries with Unlighted Modules * User Legendable Lightable ModulesUnlighted Modules Mounting Build a custom keyboard with identical button distances no matter how you stack them. Designed to plug into any printed circuit board from 1/16" to 1/8" thick, modules stack in any configuration, maintaining 11/16" button centers. For Lightable Modules which will be continuously lit, mixing ver tically mounted modules with horizontally mounted modules is not recommended; the orientation of the rectangular, lighted area will differ. See drawings. See Figure 1 Panel Cutout diagram for 6 button module mounting dimensions. Refer to drawings for other module dimensions.

The height of the lamp should not exceed .250" (6,35 mm) from the surface of the board. (Note: Grayhill does not manufacture or sell LED's or incandescent lamps). For easy light replacement, mount the lamp or LED through the back or solder side of the board (see Figure 2). This method of mounting allows you to replace light source without removing the keyboard module. The other method of light mounting (Figure 2a) requires desoldering the keyboard module then desoldering the lamp when it's necessary to replace the light source. The chart below lists ratings for a size T-1 incandescent lamp.To extend the life of the lamp, use an alternating current and reduced voltage. The chart also lists maximum temperatures the module can withstand. For higher temperatures, Grayhill offers modules made of special plastics, polyester switch housing and polycarbonate internal button. All measurements were determined under laboratory conditions.

Rotating it 180 will result in a different pin location. Please note the button identification, the pin location for the desired circuitry, and the direction of mounting. It is important to use this information when designing a printed circuit board layout and when communicating with Grayhill. See Ordering Information-Special Keyboard Modules on the next page. Circuit Diagrams The coded circuits shown are suggested possibilities and each button may carry a different circuit. Location of active pins on each button may be varied to conform with layout of the printed circuit board. Up to a 7-bit code is possible under each button.

Turning end to end will result in a different pin location. However, the dimensional relationship will remain the same. Lightable Modules-per drawing below. This drawing indicates the layout to be used for a 6 button module with light sources mounted two ways: the lamps for the upper 3 buttons are mounted from the top or component side of the board, and the lamps for the lower 3 buttons are mounted by the easy replacement method. (See also Light Source and Lamp Mounting.) Light sources, when mounted from the top side of the board, must be mounted before the keyboard modules; when mounted, lamp should extend no more than .250" (6,35 mm) above the board.

These pin numbers are directly related to the circuit diagrams. For example, if the switch under Button A of a standard module were SPST, the pins would be located at the "#2" Position. If the module were a lightable one with SPST circuitry, the pins would be located at the "#1" Position. If other locations are desired, specify them.

For unlighted module with sub-surface printed legends or insertable legends, Internal Button is acetal; Internal Cap is ABS plastic (gray); and Clear Cap is polycarbonate plastic. For lightable modules, the Internal Button and the Clear Cap are polycarbonate. The Internal Cap for gray modules is acrylic; for the black modules, the Internal Cap with window is polycarbonate. Soldering Instructions Series 82 Keyboard Modules have been successfully tested for heat resistance to soldering up to 260C (500F) for a maximum of 5 seconds. Careful flux cleaning is required since the switch is not sealed. For applications in excess of these limits or that require vapor spray or immersion cleaning, contact Grayhill. Standard Legends Telephone Keyset Two 6-button modules form the keyset. White telephone legend is molded into a gray button. SPST, 2PST, 3PST, and 4PST circuitr y available from distributors, see ordering information; order special circuitry from Grayhill. Non-Legend, Lighted Modules Standard lightable module configurations without cap slot for insertable legend. Insertable Legend Styles Special Legends Molded-In Legends For Unlighted Modules In addition to standard white legend on gray button, longwearing, molded-in legends are available in white button with black legend and white legend with red, green or black buttons. Other color combinations are possible. Printed Legends (2 Styles) Virtually anything which can be photographed can be printed. Sturdy epoxy ink printing bonds to the surface of the button. Standard printing for the gray unlighted buttons is white; standard printing for the translucent white buttons of the lightable modules is black. Top Surface Printing: Legend is applied directly to top of button. Available on all standard, unlighted modules. Sub Surface Printing: Provides maximum wear for printed surfaces. Available for lighted and unlighted gray modules. Printed internal button cap is protected by a clear outer cap. Prototypes can look professional with insertable legend modules. Just slip imprinted legend insert through the slot of the clear button cap. Legend Sheet Available for each module style. Each sheet contains commonly used symbols, terms, alpha characters, and 0-19 in News Gothic Condensed type on polyester film, ready to be cut and inserted. Deadfront legends are invisible until lit.
