The R902603434 solenoid coil is a critical component in electro-hydraulic control systems. When energized with a 24V DC supply, it generates a magnetic field that shifts the spool inside the Rexroth valve, directing hydraulic flow to the desired actuator. This model is characterized by its low hysteresis and excellent repeatability, making it ideal for precision applications such as mobile machinery, industrial presses, and injection molding equipment.
The coil housing is encapsulated with a high-performance epoxy resin that provides superior resistance to vibration, moisture, and temperature extremes. The standard DIN 43650 connector ensures compatibility with most industrial cables, and the built-in suppressor diode (in applicable variants) reduces voltage spikes, protecting both the coil and the control circuit.
For optimal performance, always verify that your hydraulic system's voltage and current ratings match the coil's specifications. Regular inspection of the connector pins and sealing gasket is recommended to maintain the IP65 protection rating.
Installation Guidelines
Ensure the hydraulic system is depressurized and the power supply is disconnected.
Remove the old coil by loosening the center mounting nut (if applicable) or unplugging the connector.
Clean the valve tube surface to remove any debris or oil residue.
Slide the new R902603434 coil over the valve tube until it sits flush against the valve body.
Tighten the mounting nut to the recommended torque (refer to valve manual) and connect the DIN 43650 plug.
Reconnect power and test for proper valve actuation without leakage.
