Hirschmann GDM21F6-D24-10D DIN 43650 Form A Solenoid Valve Connector: 24V DC LED & Diode
Right-angle 2-pole-plus-ground valve connector with 18mm contact spacing, M16 cable entry, yellow 24V DC LED indication, recovery-diode protection, screw terminals, and IP65 protection.
Visible 24V DC Status and Coil-Surge Protection
The Hirschmann GDM21F6-D24-10D, part number 934888011, is a DIN 43650 Form A solenoid valve connector for 24V DC circuits. Its integrated yellow LED provides a clear visual indication when supply voltage is present, helping technicians confirm circuit status during commissioning, troubleshooting, and maintenance.
An integrated recovery diode suppresses the inductive voltage spike produced when a DC solenoid coil is switched off, helping protect connected control electronics. The right-angle housing uses an M16 cable entry for 4.5–9mm cable, accepts 0.25–1.5mm² conductors, and secures to the device with a vibration-resistant center screw.
💡 Yellow 24V DC LED
Provides at-a-glance confirmation that supply voltage is present at the connected device.
⚡ Recovery Diode
Suppresses inductive overvoltage generated when a DC solenoid coil is de-energized.
🔌 DIN Form A Interface
Uses the standard 18mm contact spacing and a 2-pole-plus-ground configuration.
🛡️ IP65 Protection
Dust-tight construction resists water jets when the connector is correctly assembled and secured.
⚠️ 24V DC Polarity Must Be Observed
The integrated LED and recovery diode make this connector polarity-sensitive. Confirm the positive and negative connections before applying power. Also verify 24V DC operation, DIN 43650 Form A compatibility, 18mm pin spacing, a 2-pole-plus-ground interface, and the required diode orientation for the connected solenoid coil.
🏭 Industrial Applications
The GDM21F6-D24-10D is designed for 24V DC solenoid valves and compatible industrial devices used in hydraulic systems, pneumatic machinery, process-control equipment, and factory automation. It can also support compatible electromagnetic actuators, pressure sensors, and flow indicators that use the DIN 43650 Form A connection pattern.
Key Features & Benefits
- Right-Angle Cable Exit: Routes cable alongside the device to reduce required installation depth.
- M16 Cable Entry: Accommodates cable with an outside diameter from 4.5mm to 9mm.
- Screw Termination: Accepts 0.25–1.5mm² conductors for field wiring without specialized crimp tools.
- Vibration-Resistant Center Screw: Locks the connector securely to the mating device.
- Improved Handling: Grip areas on both sides make the clear housing easier to position during assembly.
- Reinforced Housing Geometry: Rounded housing edges and a strengthened contact-carrier crossbeam improve stability under mechanical stress.
- Industrial Compliance: VDE and SEV approved and RoHS compliant.

📋 Basic Wiring & Installation Overview
1. Verify Compatibility: Confirm a 24V DC circuit, DIN 43650 Form A interface, 18mm contact spacing, and the correct diode polarity for the load.
2. Prepare the Cable: Use 4.5–9mm OD cable with 0.25–1.5mm² conductors, then strip the cable according to the installation requirements.
3. Route Through the M16 Entry: Pass the cable through the gland components before completing the screw terminations.
4. Wire the Connector: Connect positive, negative, and protective ground to the correct terminals while observing LED and diode polarity.
5. Seal and Secure: Tighten the cable entry around the jacket, seat the connector and sealing components correctly, and fasten the included center screw.
6. Test Operation: Apply power and confirm the yellow LED illuminates and the connected device operates correctly.
Disconnect power before installation or service. Wiring should be completed by qualified personnel in accordance with applicable electrical requirements.
