BECKHOFF C9900-G053 Compact Push-Button Extension

Description

The BECKHOFF C9900-G053 is a compact push-button extension designed for mounting arm installation directly below landscape-format multi-touch panels. It provides physical operator controls and safety elements in immediate proximity to the HMI screen, streamlining machine control and manual override operations.

This extension unit is compatible with landscape-format multi-touch CP39xx Control Panels, as well as CP32xx-1600 and CP37xx-1600 Panel PCs. By extending the HMI frame with physical tactile controls, the unit reduces the reliance on touch-only navigation for critical system functions.

Wiring interface options allow for versatile system integration. The individual push-buttons feature signal lamps and are connected via a combination of USB and an external 19-pin round connector. The safety-critical emergency stop button operates with direct break contacts wired through the 19-pin connector for connection to standard safety relays or TwinSAFE systems.

Features

• Designed for landscape-format multi-touch CP39xx Control Panels, CP32xx-1600, and CP37xx-1600 Panel PCs.
• Horizontal mounting position directly below the HMI panel.
• Equipped with high-quality RAFI RAFIX 22FS+ round 30 mm push-button keys.
• Integrated signal lamps in each push-button for active operator feedback.
• Includes one dedicated RAFI RAFIX 22FS+ emergency stop button.
• Push-button caps allow individual marking with insertable labels.

Applications

• Operator control stations utilizing mounting-arm-compatible control panels and panel PCs.
• Machine-level HMI systems requiring physically wired emergency stop devices.
• Industrial manufacturing environments where high-use functions require physical tactile push-buttons.

Installation Guidelines

1. Verify that the HMI panel model is a compatible landscape-format BECKHOFF CP39xx or Panel PC (CP32xx-1600 / CP37xx-1600).
2. Ensure that all power supply lines to the control panel and auxiliary circuits are completely de-energized.
3. Mount the C9900-G053 housing to the bottom margin of the panel enclosure, ensuring all environmental seals are properly seated to maintain the assembly's protection class.
4. Connect the internal wiring paths to the HMI panel, including the internal USB connection.
5. Wire the 19-pin round connector to the appropriate machine control lines, making sure the emergency stop break contacts are correctly integrated into the safety monitoring circuit.
6. Secure all cable assemblies and mounting hardware before applying system power.
7. Test each push-button, indicator lamp, and the emergency stop function to verify correct wiring and signaling before putting the system into operation.
