BECKHOFF C9900-G050 Compact Push-Button Extension

Description

Designed for direct physical integration with landscape multi-touch systems, the BECKHOFF C9900-G050 provides localized, tactile operator controls below compatible HMI screens. This horizontal push-button extension mounts directly to the underside of multi-touch CP39xx Control Panels and CP32xx-1600 and CP37xx-1600 Panel PCs with mounting arm configurations.

The unit features industrial-grade control elements, including round 30 mm RAFI RAFIX 22FS+ push-buttons with integrated signal lamps and a high-visibility emergency stop button. It bridges physical hardware inputs and digital control networks by utilizing dual-path communication via USB and a standard 19-pin round connector. This layout ensures both standard control operations and safety-critical stop functions are routed reliably through appropriate channels.

Features

• Compatible with landscape-oriented Beckhoff multi-touch panels and Panel PCs.
• Robust RAFI RAFIX 22FS+ round 30 mm push-button keys with built-in status lamps.
• Integrated high-reliability safety emergency stop key (RAFI RAFIX 22FS+).
• Removable push-button caps allowing individual marking and custom inserts.
• Flexible communication routing via USB and a rugged 19-pin round connector.
• Ergonomic horizontal positioning below the main panel screen.

Applications

• Automotive manufacturing assembly lines and robotic cells.
• CNC machining centers and heavy metal-forming machinery.
• Process control panels in chemical, water-treatment, and power industries.
• Custom HMI operator stations requiring physical tactile indicators alongside touch screens.

Installation Guidelines

To ensure long-term mechanical stability and electrical reliability, follow these engineering guidelines during mounting:

• Mechanical Alignment: Secure the C9900-G050 directly to the lower edge of the compatible multi-touch panel housing using the supplied mounting hardware. Verify that seals are properly aligned to maintain ingress protection ratings.
• Cable Routing: Ensure that both the USB connection and the 19-pin round cable have sufficient strain relief and are routed away from high-voltage AC lines to prevent EMI noise on the signal lamp controls.
• Safety Grounding: Connect the ground terminals in accordance with standard industrial machine safety practices. The safety-critical emergency stop break contacts must be wired directly into a certified safety relay or safety PLC input module via the 19-pin interface.
