This trio of high-performance CANbus keyboards—PKI, PKD, and PKR—bring compact design, high configurability, and reliable tactile feedback into one seamless solution, redefining how operators interact with their machine environments.
3 series of rugged keypads for centralized control
PKI series – The modular version
Offering flexible layouts (2–15 keys) and removable icon inserts, the PKI series supports rapid customization for any application. Available in 15mm or 24mm button sizes, it ensures precise control—even when wearing gloves. The keypad delivers clear tactile feedback and configurable RGB LED rings for status indication, all within a compact, sealed design.
Key Benefits:
- Replaceable laser-etched icon inserts
- RGB LED rings and icons
- Easy reconfiguration
- CANopen and J1939 support
- IP67/IP69K protection for outdoor use

PKD series – The versatile option
The PKD series combines three essential control functions—joystick, rotary encoder, and pushbutton—into a single, space-saving knob. With CANopen and J1939 protocols embedded, this unit simplifies user interaction with touchscreen or display interfaces while maintaining operational safety and comfort. Designed for intuitive operation, the PKD reduces training time and streamlines access to multiple machine functions.
Key Benefits:
- Ergonomic all-in-one design
- Customizable LED ring (8 segments)
- Waterproof and UV resistant (IP67/IP69K)
- Easy vertical, horizontal, or symmetrical mounting
- Up to 3 million operations

PKR series – The ultra-compact model
Designed for harsh conditions, the PKR keypad offers a soft-touch rubber overlay with precise tactile response and enhanced grip. Despite its ultra-compact form factor, it supports dynamic multi-color LED feedback, customizable laser-etched icons, and up to 3 RGB indicators per button—ideal for multi-function control in tight spaces.
Key Benefits:
- Ultra-compact and glove-friendly
- High-density button layout
- LED icons and points (0 to 3 per key)
- Superior shock, vibration, and UV resistance
