The **XHS35F-100-R2-FS-XPROGA** is a high-performance hollow-shaft incremental encoder manufactured by **BEI Sensors (Sensata)**. This specific series is known for its ruggedness and versatility in industrial environments. --- ### 1. Part Number Breakdown & Specifications The alphanumeric code describes the specific electronic and mechanical configuration of the device: | Segment | Code | Description | | :--- | :--- | :--- | | **Model Series** | XHS35 | Extra Heavy Duty Hollow Shaft (3.5" diameter housing). | | **Bore Size** | F | 1-inch diameter hollow shaft with a flex mount. | | **Resolution** | 100 | 100 Cycles Per Revolution (CPR). | | **Connection** | R2 | M12 radial connector or specific radial lead exit. | | **Output Type** | FS | Differential Line Driver (5V to 28V logic depending on supply). | | **Electronics** | XPROGA | Programmable output electronics/features. | --- ### 2. Key Electronic Features #### A. Programmable Electronics (XPROGA) The "XPROGA" suffix indicates that the encoder utilizes programmable internal logic. This allows for: * **Resolution Flexibility:** While the base might be set to 100 CPR, the internal electronics can often be factory-scaled or configured for specific pulse counts. * **Universal Voltage:** Typically supports a wide range of input voltages (e.g., 5VDC to 28VDC), making it compatible with various PLC and controller inputs. #### B. Differential Line Driver (FS) The encoder uses a differential output (RS-422 compatible). This provides high noise immunity because: * It transmits a signal and its complement (A and A-not, B and B-not, Z and Z-not). * Any electrical noise picked up along the cable is cancelled out at the receiving end (Common Mode Rejection). #### C. Protection Circuits Industrial encoders like the XHS35F include built-in electronic protection: * **Reverse Polarity Protection:** Prevents damage if the power supply wires are accidentally swapped. * **Short Circuit Protection:** Safeguards the output drivers if the signal wires touch a ground or power line. --- ### 3. Application Use Cases Due to its heavy-duty design and electronic precision, it is commonly used in: 1. **Motor Feedback:** Monitoring the speed and position of large AC/DC motors. 2. **Material Handling:** Conveyor synchronization and sorting systems. 3. **Oil & Gas:** Drawworks and harsh environment motion control. --- ### 4. Technical Summary Table | Attribute | Specification | | :--- | :--- | | **Supply Voltage** | 5V to 28V DC | | **Max Frequency** | Up to 100 kHz - 300 kHz (varies by config) | | **Current Consumption** | ~100mA max | | **Output Format** | Incremental (A, B, Z Index) | | **Sealing** | IP65 or IP67 depending on shaft seal |
