The MKU, part of the CattronControl™ family, is a compact keypad control unit for cranes, lifting equipment and a diverse range of machines. The MKU employs advanced dual processor electronics and safety critical software, protected in an ergonomic and robust aluminum and rubber housing that is well suited for use in aggressive industrial environments.


The MKU features an external RFID Transkey™ for simple unit configuration. This allows facilities to quickly deploy spare units by simply swapping the RFID Transkey between the operating unit and a spare, so downtime and spares holding are minimized.


The MKU has 12 dual step push buttons that can be indepedently configured or set to operate cranes and machines with up to 5 reversing functions, plus typical start and horn.


There are so many possibilities with its high reliability push buttons, RF options, feedback onto the 4 multi-function LEDs, tandem, multi-crane/machine selection capabilities, RFID Transkey and global compliance. This tough and compact controller is ideal for operation in numerous applications and operators maintain total freedom of movement for safe and efficient operations.


Features:
• For control of cranes and machines with digital or analog drive systems, (digital control) 
• LEDs for status and feedback
• High safety-class through redundant hardware and software architecture
• Approvals and frequencies for worldwide deployment
• IP65 housing made of high impact-resistant aluminum + rubber for tough indoor or outdoor environments
• Control up to five dual step drives with the 12 two-step push buttons, plus on/off, E-Stop and rotary switch (optional)
• Customer-specific layout and face plate options
• Compatible with a number of machine control units featuring various interface options
• System configuration via secure wireless (RFID) Transkey for simplification of spares holding
• Tandem and multi-transmitter and/or receiver operation
• CE compliant
