Product Information
Full details
The Murrelektronik 7000-29005-0000000 is a field-wireable valve plug designed for connecting magnetic coils in pneumatic and hydraulic systems. It is ideal for engineers and technicians working with industrial automation, providing a reliable connection for solenoid valves. A key benefit is its integrated LED indicator and VDR surge protection. However, its IP00 degree of protection means it requires a protected environment and is not suitable for direct exposure to dust or moisture.

FAQs
What is the IP rating of this valve plug?
The Murrelektronik 7000-29005-0000000 has an IP00 degree of protection, meaning it offers no protection against dust or water and must be installed in a controlled, dry environment.
Can I use this plug with a 12V system?
No, this valve plug is designed for a 24V AC/DC power supply. Using it with a different voltage may cause malfunction or damage.
How do I wire the plug in the field?
You will need to strip the cable wires and connect them to the internal screw terminals. The plug is designed for field-wireability, allowing connections to be made on-site.
What does the LED indicator signify?
The LED indicator provides a visual confirmation that the plug is receiving the correct voltage (24V AC/DC), helping with diagnostics.
What is the function of the VDR protection?
The VDR (Voltage Dependent Resistor) acts as a surge suppressor, protecting the connected solenoid coil from damaging voltage spikes.
What is the maximum cable diameter this plug can accommodate?
This plug is designed for cable diameters ranging from 6 to 8mm.
Is this plug suitable for outdoor use?
No, due to its IP00 rating, it is not suitable for outdoor use or any environment exposed to moisture or dust.
Troubleshooting
Valve is not actuating, and LED is off.
Check the 24V AC/DC power supply connection to the plug. Verify wiring at the screw terminals. Ensure the correct wires are connected to the power input and ground terminals.
Valve is not actuating, but LED is on.
Verify that the correct wires are connected to the solenoid coil output terminals. Check for continuity of the coil itself. Ensure the cable diameter is properly secured and not causing strain on the terminals.
Intermittent operation or LED flicker.
Inspect the screw terminal connections for tightness. Ensure the cable is securely fastened within the plug's cable entry to prevent movement. Check for any damage to the internal wiring or the solenoid coil.
Plastic housing shows signs of degradation.
While resistant to many chemicals and oils, some aggressive media may cause degradation. Refer to Murrelektronik's chemical resistance charts or conduct specific testing for your application's environment. Relocate the plug to a less aggressive area if necessary.
Pros and Cons
Pros
- Offers a reliable and secure connection for solenoid coils.
- Integrated LED and VDR provide diagnostic and protection benefits.
- Field-wireable design enhances installation flexibility.
- Conforms to industry standards for compatibility.
- Durable housing resistant to common industrial chemicals and oils.
Cons
- IP00 degree of protection limits use to dry, protected environments.
- Requires manual wiring, which can be time-consuming.
- Resistance to aggressive media needs individual testing.
- Limited to 24V AC/DC, not suitable for higher voltage applications.
Setup, Compatibility & Care
Setup:
- Ensure power to the connected system is off.
- Strip the appropriate length of cable for the desired wires (typically for the 2P+E connection).
- Connect the wires to the designated screw terminals within the plug. Ensure proper polarity if applicable.
- Secure the cable in the designated entry for diameters ranging from 6 to 8mm using the appropriate gland or sealing mechanism.
- Screw the housing together firmly.
Compatibility:
- Designed for solenoid coils conforming to DIN EN 175301-803 Form A (18 mm pin spacing).
- Suitable for 24V AC/DC power supplies.
- Compatible with cable diameters of 6-8mm.
Care:
- Clean the exterior of the plug with a dry or slightly damp cloth. Avoid harsh chemicals or solvents.
- Due to its IP00 rating, ensure the plug is installed in a clean, dry environment, protected from dust and moisture. Do not expose directly to water or significant environmental contaminants.
