Product Overview: Heidenhain AC 2620 Connecting Cable
The Heidenhain AC 2620 is a premium, high-shielded connecting cable designed specifically for the transmission of high-frequency signals in industrial motion control systems. In the world of precision measurement, the quality of the cabling is as critical as the encoder itself. The AC 2620 is engineered to connect Heidenhain rotary and linear encoders to various CNC controls or interface electronics, ensuring that position data remains accurate and free from external interference.
Technical Specifications and Signal Integrity
The AC 2620 features a specialized internal structure with twisted-pair conductors and high-density braided shielding. This design is essential for protecting sensitive 1Vpp (sinusoidal) or EnDat (serial) signals from Electromagnetic Interference (EMI) commonly found in industrial environments near high-power motors and VFDs. The cable is manufactured with a high-flexibility jacket, making it suitable for both static and dynamic installations within machine cable chains.
Key Technical Characteristics
- Part Number: AC 2620.
- Cable Type: Multicore shielded cable.
- Connector Options: M12, M23, or D-Sub (depending on variant).
- Signal Compatibility: 1Vpp, TTL, and EnDat 2.2.

Advanced Engineering for Machine Reliability
Using genuine Heidenhain AC 2620 cables prevents the «signal jitter» often associated with third-party cabling. The cable’s low capacitance ensures that high-speed serial data (EnDat) can be transmitted over longer distances without data loss or timing errors. This reliability is vital for maintaining the surface finish quality in CNC milling and turning operations where every micron counts.
