HEIDENHAIN ROQ 425 512 27S17-93 326172-01

HEIDENHAIN ROQ 425 Absolute Rotary Encoder Description This is a HEIDENHAIN ROQ 425 absolute rotary encoder, part number 326 172-01. It is a robust industrial encoder designed for accurate position feedback in a wide range of automation applications. As an obsolete model, it is an essential component for repairing and maintaining existing machinery, preventing the need for costly system-wide upgrades. This encoder operates on a supply voltage of 10 to 30V DC and provides position data via an SSI interface. Specifications Manufacturer: HEIDENHAIN Type: Absolute Rotary Encoder Model: ROQ 425 Id.Nr.: 326 172-01 Resolution: 512 steps per revolution Interface: SSI (Synchronous Serial Interface) Supply Voltage: 10V to 30V DC Shaft: Solid shaft Label Info ROQ 425 512 27S17-93 Id.Nr. 326 172-01 S.Nr. 8 407 038 C 10V…30V Application Typically used in machine tools, robotics, packaging machines, and other automated systems where precise angular position is critical for operation. Country of Origin Made in Germany. CO2 Impact Choosing this reused encoder over a new one saves approximately 20 kg of CO2 emissions, which is comparable to the emissions from driving a car for 100 km.

FAQ Question?What is the communication interface for this ROQ 425 encoder? Answer?This encoder uses the Synchronous Serial Interface (SSI) for data transmission, which is a common standard for absolute encoders, providing reliable position data. Question?Is this encoder compatible with a 5V TTL system? Answer?No, the specified supply voltage is 10V to 30V DC. It is not designed for 5V TTL logic levels and requires a compatible controller or interface card that can handle the specified voltage range. Question?Can this absolute encoder’s zero position be reset? Answer?Yes, like many HEIDENHAIN absolute encoders, the zero position can typically be set electronically via a specific input pin on the connector or through the control system’s software, depending on the machine’s implementation. Please consult the machine’s technical manual for the specific procedure.
