Bosch Rexroth 3P Z5L1 Plug-in Connector | R900057292 R900032020 | Solenoid Valve Plug

LIC Hydraulic offers the Bosch Rexroth Z5L1 Series, the industry-standard electrical interface for hydraulic solenoid and proportional valves. These 3-pin (3P) plug-in connectors comply with DIN EN 175301-803 standards, ensuring reliable power transmission and signal integrity in harsh industrial environments. Our inventory covers the full range of Rexroth part numbers, including R900057292, R900032020, and R901017029. Built to withstand extreme vibrations and temperature fluctuations, these connectors provide an airtight seal to protect sensitive electrical contacts from moisture, dust, and hydraulic oil.

Technical Specifications (Bulleted List)

• Type: 3-PIN Connector (2 Poles + PE)

• Standard: DIN EN 175301-803 (Form A)

• Protection Rating: $IP65$ (Dust-tight and protected against water jets)

• Operating Voltage: Supports AC/DC systems depending on model (e.g., $24\text{V}$ to $230\text{V}$)

• Material: Impact-resistant Polyamide with high thermal stability

• Compatibility: Direct fit for Rexroth WE6, WE10, and proportional series valves.

Key Technical Advantages

• Universal Compatibility: Designed to be a drop-in electrical interface for Bosch Rexroth coils and other major hydraulic brands using the Form A standard.

• Vibration-Proof Locking: Features a central fastening screw with a captured washer system that prevents loosening in high-vibration mobile applications.

• Enhanced Safety: High-quality internal insulation materials prevent electrical arcing, ensuring the safety of your PLC and control circuitry.

• Diagnostic Ready: Available versions with integrated LED indicators allow for instantaneous troubleshooting by showing the power status at the valve.

Application Areas

• Factory Automation: Wiring for manifold systems in CNC machines and injection molding.

• Mobile Hydraulics: Control interfaces for excavators, cranes, and agricultural machinery.

• Heavy Industry: Powering solenoids in steel mills and paper processing plants.

Expert Maintenance Tips

• Proper Seating: Always ensure the flat rubber gasket is present and undamaged during installation. A missing gasket is the primary cause of electrical failure due to fluid ingress.

• Torque Specification: Tighten the central screw to the specified torque. Overtightening can crack the connector housing, while undertightening will compromise the $IP65$ seal.

• Voltage Verification: When replacing an LED connector (e.g., series R9003139xx), verify that the voltage rating of the plug matches your system ($12\text{V}$, $24\text{V}$, or $110/220\text{V}$) to avoid burning out the indicator circuit.
