TURCK 2689UA,BI2-CRS260-ADZ30X3-B3131 S34,4275400UR SENSOR ,SR

Description:

The Turck BI2-CRS260-ADZ30X3-B3131 S34 Inductive Proximity Sensor is used in hydraulic and industrial automation systems for non-contact metallic object detection and high-pressure cylinder position sensing. Commonly installed in hydraulic cylinders, injection molding machines, clamping systems, metal forming equipment, and heavy industrial machinery requiring weld-field immune sensing performance. Maintenance teams and system integrators use this part for replacement, retrofit, automation upgrades, or high-pressure position feedback applications in demanding industrial environments.

Applications:

The Turck BI2-CRS260-ADZ30X3-B3131 S34 is commonly used for piston position monitoring, hydraulic cylinder feedback, clamp position verification, and machine sequencing in hydraulic and PLC-controlled systems. Its high-pressure stainless steel probe construction allows installation directly into hydraulic equipment while maintaining reliable sensing performance in environments exposed to welding currents, magnetic interference, and vibration. The S34 version is particularly suited for automotive manufacturing, robotic welding cells, and heavy-duty hydraulic machinery. The 2689UA and 4275400UR numbers are customer-specific or distributor identifiers associated with this sensor variant.
