Why Choose the Hirschmann GDMZRC21223210 Form A Connector?
The Hirschmann GDMZRC21223210 DIN 43650 Form A connector provides a 12V DC LED indicator for checking voltage at a compatible solenoid valve. Its diode helps protect the source and load against overvoltage.
The connector includes an EPDM flat gasket and a central fixing screw. Its 1/2 inch NPT entry accepts cable from 4 to 11 mm in diameter for field wiring through protected screw terminals.
💡 Visible Voltage Check
Check voltage presence locally at the valve connector.
🔧 Field Wiring
Connect the cable directly using the internal terminals.
🛡️ Diode Protection
Helps protect the source and load against overvoltage.
⚙️ Secure Attachment
The central screw helps keep the connector secured under vibration.
⚠️ Confirm Connector Compatibility
Confirm the Form A interface, 18 mm contact spacing, and two poles plus ground before ordering. Match the 12V DC circuit to the application and check the 1/2" NPT entry against your cable connection. Review the product images for dimensional drawings.
💡 Circuit Function
The 12V DC LED indicates voltage presence at the connector. The diode provides overvoltage protection for the source and load. Select the circuit version that matches the connected equipment.
Key Features & Benefits
- Flexible termination options: The combination terminal accepts flexible wire with wire end ferrules or fork and eye cable terminals secured directly under the screw head.
- Conductor protection: The terminal design protects conductors at the screw connection during wiring.
- Vibration resistant retention: Central screw locking helps reduce connection loosening on operating machinery.
- Serviceable field connection: Hardwired construction allows the field cable to be terminated inside the connector during installation or replacement.
⚙️ Typical Applications
Use with compatible hydraulic and pneumatic solenoid valves or electromagnetic actuators. It can also connect compatible pressure sensors and flow indicators when the interface and circuit requirements match.
