T series HMG 00T 0T 1T 2T 3T Circular Watertight Socket

What is HMG 00T 0T 1T 2T 3T Circular Watertight Socket?

The HMG 00T to 3T Circular Watertight Socket is a high-reliability circular metal socket designed for harsh environments where sealing and durability are critical. It features a rugged, compact housing with IP68 sealing, making it a trusted watertight socket for applications exposed to water, dust, or sterilization processes. For high-purity or controlled environments, this series also offers vacuumtight socket versions. Widely used in medical equipment, instrumentation, and industrial systems, the medical socket provides safe, secure connections with push-pull latching mechanisms. Available in multiple sizes from 00T to 3T, the HMG series offers a versatile solution for engineers requiring compact, sealed, and water resistant socket performance.

Key Advantages

• Safe push-pull self-locking system

• Solder and PCB pin contacts (straight and angled).

• High-density mounting, space-saving, with cutout sizes M9/M12/M15/M18.

• 360-degree shielding provides comprehensive EMC protection (electromagnetic interference resistance).

• Reliable watertight sealing — Ensures IP68‑grade waterproof performance for harsh environments.

• Medical‑grade compatibility — Suitable for diagnostic, imaging, and laboratory devices.

• High‑density configurations — Supports up to 32 contacts for complex system integration.

How to Select the Right Pins for T Series HMG 00T / 0T / 1T / 2T / 3T Circular Watertight Sockets

Choosing the correct socket configuration ensures full compatibility with your T Series plugs and reliable sealing in harsh environments.

1. Confirm Plug Compatibility:
   Ensure the selected HMG socket matches the corresponding T Series plug (FGG / TGG) in size (00T / 0T / 1T / 2T / 3T), insert configuration, and keying (e.g., G key).

2. Determine Contact Requirements:
   Identify the number of contacts required for your application (e.g., 2–32 pins), based on your power and signal distribution needs.

3. Check Contact Diameter (øA):
   Match the pin diameter to the expected current load and signal transmission. Refer to the pin configuration chart for available options.

4. Verify Cable & Panel Fit:
   Ensure the socket supports your cable outer diameter and meets panel-mounting dimensions for your enclosure.

5. Consider Sealing & Standards:
   Confirm the connector meets IP68 sealing when mated and complies with IEC / RoHS requirements for long-term reliability.
