Order numbers: 693-2391 and 693-2388 with fixed legends and without different format. Self-adhesive matrix membrane keypads. The typical feature of these keypads is the insertable polycarbonate sheet, with printed standard legends on one side, while the other side can be provided with user-defined legends (written, printed, or transferred symbols), thus allowing totally customized labeling and eliminating any keypad orientation constraint. The 4 x 4 and 4 x 3 keypads are labeled by inserting two of the four sheets supplied into the keypad pockets. For the 4 x 1 keypad, one of the two sheets supplied must be inserted. Alternatively, other suitable paper or polycarbonate labeling sheets can be used. Punched holes in the labeling sheet allow individual keys to be displayed (via LED), and a translucent labeling sheet can be used to provide background lighting. After the labels have been inserted, the self-adhesive keypad can be glued to any suitable clean, flat surface. The flexible end of the keypad can be connected to PCB pin headers by means of a socket strip. Each keypad has a top layer of black polycarbonate with silver embossing and imprinting. It includes a double-sided silver inscription sheet with black inscription on one side, and the other side without inscription. Supplied with a data sheet. Connection cable length: 100 mm. Contact material: Silver. Actuator material: Polycarbonate. Mechanical life: 1,000,000 operations.
