iKey's innovative SL-91 mobile keyboard was designed for demanding manufacturing, material-handling and remote data-entry applications. Its unique epoxy-coated keys are arranged for convenient gloved-hand use. It features a compact design, mounting holes in the case and a 10-key numeric pad. Like other keyboards in the iKey range, the SL-91 is built with a robust polycarbonate case and an industrial silicone keypad, sealing it against dust, liquids and corrosives. The SL-91 is a true workhorse, used all over the world. It includes red LED backlighting.
