Type B Series General Data

Full-Travel Keys RS 76 M and RS 76 C The Type B series keyboardsare based on the RS 76 M full-travel keys (mechanicalcontacts) or the RS 76 C keys (solid state switch withHall-IC). Keycaps The keycaps of the B6-C and B8-C industrial keyboards are twoshot moulded. The symbols form an integral component of the keycap,thereby excluding any abrasion. The keycaps of the other keyboards are laser engraved.In this process, a laser is used for burning the symbolsinto the keycaps after keyboard assembly. In this way, customer-specific layout variants can be produced without any problem.
