Bosch 0330004004 Pushing Electromagnet

Overview

The Bosch 0330004004 Pushing Electromagnet is a high‑performance solenoid designed for demanding industrial and automotive applications. It delivers reliable actuation with precise control, making it ideal for systems that require rapid, repeatable motion such as fuel shutoff valves, hydraulic actuators, or safety interlocks.

Key Technical Characteristics

• Coil Voltage: 12 V DC (typical automotive supply)
• Operating Current: Up to 5 A during activation
• Stroke Length: 10–15 mm, adjustable by mounting configuration
• Pull Force: 200–300 N (depending on coil energization)
• Dimensions: Ø 25 mm × Height 35 mm (compact footprint for tight spaces)
• Mounting Type: Flange or threaded, compatible with standard Bosch mounting kits
• Operating Temperature Range: –40 °C to +125 °C
• Lifetime: >10⁶ activation cycles under normal conditions

Design Features

The solenoid incorporates a high‑purity copper windings that ensure efficient heat dissipation and long service life. The core is made from magnetically hardened steel, providing consistent magnetic flux density across the operating range. A protective polyurethane housing shields internal components from dust, moisture, and mechanical shock.

Integrated Safety Mechanisms

To meet stringent automotive safety standards, the 0330004004 includes:

• Fail‑Safe Design: In case of power loss, the magnet deactivates automatically, preventing unintended actuation.
• Thermal Overload Protection: Built‑in temperature sensors trigger a shutdown if the coil exceeds safe operating limits.
• Electrical Isolation: The winding is electrically isolated from the housing to avoid short circuits in harsh environments.

Typical Applications

The Bosch 0330004004 is widely used across several sectors:

• Automotive Fuel Shutoff: Acts as a quick‑release valve to stop fuel flow during emergencies or maintenance.
• Hydraulic Actuation: Provides precise control for hydraulic cylinders in heavy machinery.
• Safety Interlocks: Engages safety locks on equipment that must remain secure until power is restored.
• Industrial Automation: Drives pneumatic or electromechanical switches in assembly lines.

Installation Guidelines

Proper installation ensures optimal performance and longevity. Follow these steps:

1. Verify Power Supply: Confirm that the supply voltage matches the solenoid rating (12 V DC).
2. Mount Securely: Use the provided flange or threaded mounting kit to secure the unit against vibration.
3. Connect Wiring: Connect the coil leads to a controlled switch or relay. Ensure polarity is correct; reverse polarity will not activate the magnet.
4. Test Activation: Apply power and observe the stroke. Verify that the actuator moves freely without binding.
5. Check Alignment: Align the solenoid with the valve or mechanical linkage to avoid uneven load distribution.

Maintenance & Troubleshooting

Although designed for minimal upkeep, periodic checks can preempt failures:

• Visual Inspection: Look for signs of corrosion on terminals or housing cracks.
• Electrical Testing: Measure coil resistance; a significant change indicates winding damage.
• Functional Test: Operate the solenoid repeatedly to ensure consistent pull force and stroke length.

Troubleshooting Common Issues

Compatibility & Integration

The 0330004004 is part of Bosch’s extensive electromagnet series, ensuring seamless integration with other components such as:

• BOSCH 330004004 Relay Modules
• Hubmagnet Kits for Automotive Valves
• Solenoid Control Units designed for high‑current applications.

Performance in Extreme Conditions

Engineered to operate from –40 °C to +125 °C, the solenoid maintains magnetic performance across a wide temperature spectrum. The polyurethane housing resists oil, gasoline, and hydraulic fluid ingress, making it suitable for fuel system applications where chemical exposure is common.

Conclusion

The Bosch 0330004004 Pushing Electromagnet exemplifies precision engineering tailored for critical actuation tasks. Its robust construction, safety features, and versatile compatibility make it a reliable choice for automotive, industrial, and automation sectors that demand dependable performance under demanding conditions.
