Introduction to the 6FX2007-1AC04
When machine operators need reliable manual control in demanding production environments, the 6FX2007-1AC04 from Siemens delivers a practical solution. This hand-held unit is part of the SINUMERIK FM-NC/840D family, designed for direct operator interaction with CNC machines. Its coiled cable spans 3.5 meters, providing flexibility without clutter. With two emergency-stop channels and a two-channel, three-step permissive switch, it prioritizes safety during setup and intervention tasks.
The device consumes a maximum of 6 W and draws no more than 250 mA without load, making it energy-efficient. Its compact dimensions—114 mm wide, 110 mm high, and 250 mm deep—allow easy handling even in tight spaces. The housing length of 252 mm and approximate weight of 1.4 kg contribute to a sturdy yet portable feel.

Key Features and Technical Specifications
The 6FX2007-1AC04 offers several technical parameters that matter for daily operation. Below is a structured breakdown of its core specifications:
- Coiled cable length: 3.5 m
- Emergency-stop channels: 2
- Permissive switch channels: 2 (3 steps)
- Max power consumption: 6 W
- Max current consumption (no load): 250 mA
- Scanning frequency: max 2 kHz
- Max cable length to sequence electronics: 200 m
- Dimensions (W x H x D): 114 x 110 x 250 mm
- Weight: approx. 1.4 kg
One distinctive spec is the dual emergency-stop channels, which provide redundancy for critical stop functions. This redundancy reduces the risk of single-point failures, enhancing operator safety. Additionally, the 2 kHz scanning frequency ensures responsive input detection, which is crucial for precise jogging or setup movements.
Real-World Applications
In CNC machining centers, the 6FX2007-1AC04 serves as a portable control pendant, allowing operators to move freely around the machine while maintaining full control. Its coiled cable prevents tangling, and the 200 m maximum cable length to sequence electronics offers installation flexibility. The unit is also suitable for setup and maintenance tasks where precise, low-speed movements are necessary. Furthermore, the three-step permissive switch enables gradual speed control, which is beneficial during tool alignment or workpiece inspection.

Installation and Setup Guide
Proper installation of the 6FX2007-1AC04 ensures reliable performance. Begin by connecting the coiled cable to the sequence electronics, respecting the 200 m maximum length. Secure the cable to avoid strain on the connector. Mount the hand-held unit in a location that allows easy access, but ensure it is not exposed to excessive vibration or impact. The unit operates within an ambient temperature range of 0 to 45 °C, so avoid placing it near heat sources. For storage or transport, the temperature range extends from -20 to +60 °C, and relative humidity should be kept between 5% and 95% (storage) or 5% and 80% (operation) at 25 °C.
Maintenance and Reliability Tips
To maintain the 6FX2007-1AC04 in optimal condition, perform periodic inspections of the cable and connectors for wear or damage. Check the emergency-stop and permissive switch functions regularly to verify they operate correctly. Keep the unit clean and free from dust, but avoid using aggressive solvents that could damage the housing. Since the device is not rated for extreme environments, protect it from moisture and excessive humidity. Following these simple practices can extend the service life and reduce downtime.
Troubleshooting Common Issues
If the hand-held unit does not respond, first verify that the cable is properly connected and within the 200 m limit. Check the power supply to ensure it meets the 6 W maximum requirement. If the scanning frequency seems sluggish, confirm that the unit is not operating beyond its 2 kHz capability. For persistent issues, consult the official Siemens documentation or contact AutoDCSTech for technical support. Always follow the manufacturer's safety manual when performing any diagnostic procedures.
