Rugged Performance in a Compact Design

The MK (Metal Keypad) Controllers give operators of heavy equipment the best of both worlds: a small, hand-held, push-button controller with a tough, metal housing. Like all Laird Technologies products the MK controllers are built to excel in heavy duty industrial environments. They are rugged, lightweight units that are ergonomically designed and available for use with any of the current Laird Technologies Portable Radio Remote Control Systems. The MK controllers are designed to provide message security, long battery life, quick response time, and safe, accurate control of overhead cranes and other industrial equipment. Designed for harsh enviromnets, the MK controller is made of extruded aluminum with a hard, anodized exterior with the endcaps are fitted with high-impact resistant rubber for added durability.

Key Features

  • For use with most CattronControl Systems
  • Can be used to upgrade existing single- and dual-pressure keypad controllers
  • Color-coded "i-Key" adds security and eliminates need for specific spare controllers
  • Extremely durable housing made of extruded aluminum ergonomically designed with curved housing and rubber grips for comfortable handling
  • No need for additional carrying cases or protective housings
  • Separate watertight power ON/OFF switch and pull-on/ push-off STOP switch protected by rubberized end-cap "bumpers"
  • Sealed elastomer keypad with large, epoxy-coated push-buttons for single- and/or dual-pressure operation
  • Combined switch board and encoder board eliminate interconnect wiring and therefore increase controller reliability
  • Dual pressure models especially suited for VFD operation
