Description
HMI Brass Cable Gland 12mm (1/2”) – Single & Double Compression
The HMI Brass Cable Gland 12mm (1/2”) – Single & Double Compression is a nickel-plated brass cable-entry solution available in two configurations: SC012 Single Compression and DC012 Double Compression. HMI lists both variants in its standard cable-gland range, with a 12mm (1/2”) gland size and BSC (British Standard Conduit) entry thread.
The two versions should not be treated as interchangeable. The Single Compression SC012 is listed for armoured and unarmoured cables and grips the cable’s outer sheath, while the Double Compression DC012 is intended for armoured cables and seals/grips the inner and outer sheath while the cone and ring clamp the armour.
For broader selection guidance, see Thunderbolt’s Cable Gland Supplier India: 15 Expert Tips to Choose the Right Cable Gland. It explains why cable OD, cable construction, armour, thread and installation environment should be checked before selecting a gland.
HMI 12mm Single Compression Cable Gland – SC012
The HMI SC012 is the Single Compression version of this 12mm (1/2”) cable gland. HMI specifies it for indoor or outdoor applications with armoured or unarmoured cables. Its primary function is to grip the outer sheath of the cable. The gland is manufactured in nickel-plated brass and uses a BSC entry thread. Earth Tag and Shroud are listed as accessories available on request.

HMI SC012 vs DC012: Which Cable Gland Should You Choose?
| Feature | SC012 Single Compression | DC012 Double Compression |
| Gland Size | 12mm (1/2”) | 12mm (1/2”) |
| Cable Construction | Armoured / Unarmoured | Armoured |
| Main Function | Grips outer sheath | Seals inner & outer sheath and clamps armour |
| Armour Clamping | No | Yes |
| Construction | Single compression | Double compression |
| Material | Nickel-Plated Brass | Nickel-Plated Brass |
| Thread | BSC | BSC |
| Typical Selection | Suitable where outer-sheath gripping is required | Suitable where armour termination is required |
The correct choice therefore depends primarily on the cable construction and termination requirement, not simply on the 12mm label.
How to Select the Correct HMI 12mm Cable Gland
Before purchasing the HMI 12mm gland, check these points:
1. Check the actual cable outside diameter
Do not select a cable gland solely from the conductor cross-section or the nominal gland designation. The actual cable OD must be compatible with the gland’s sealing/gripping arrangement.
2. Identify armoured or unarmoured construction
For an unarmoured cable, SC012 may be relevant where its specifications match the installation. For an armoured cable requiring armour clamping, DC012 may be the appropriate configuration. HMI specifically differentiates these applications.
3. Confirm the thread
HMI lists the standard Single and Double Compression products with BSC entry thread. Make sure the enclosure or equipment entry matches the required thread.
4. Check the installation environment
Consider whether the cable entry is indoors or outdoors and whether the project requires additional environmental protection, sealing or accessories.
For more information, read Thunderbolt’s What Is IP Rating on Cable Glands and Why Does It Matter?.
5. Match the gland to the project specification
For industrial procurement, confirm the manufacturer’s technical information, cable datasheet, enclosure entry and project specification rather than relying on the nominal 12mm size alone.
Applications
The HMI Brass Cable Gland 12mm (1/2”) can be considered for cable-entry applications in electrical panels, control panels, instrumentation systems, electrical enclosures, industrial equipment, automation installations and machinery, subject to the cable and installation requirements.
The SC012 is listed for armoured and unarmoured cables, whereas the DC012 is specifically listed for armoured cables. This distinction is important when selecting the gland for an electrical installation.

Frequently Asked Questions – HMI Brass Cable Gland 12mm
1. What is the HMI Brass Cable Gland 12mm?
The HMI 12mm cable gland is available as SC012 Single Compression and DC012 Double Compression. Both are listed by HMI as nickel-plated brass cable glands with BSC entry thread.
2. What is the difference between HMI SC012 and DC012?
SC012 is the Single Compression version for armoured or unarmoured cables and grips the outer sheath. DC012 is the Double Compression version for armoured cables and seals/grips the inner and outer sheath while clamping the armour.
3. Is a 12mm cable gland suitable for a 12mm diameter cable?
Not necessarily. The 12mm (1/2”) designation is the HMI gland-size designation. It should not automatically be treated as the permitted cable OD. Always verify the applicable manufacturer’s selection data against the actual cable outside diameter.
This is especially important because cable-gland discussions and technical guides repeatedly emphasise matching the gland to the cable rather than assuming the nominal gland size equals cable diameter.
4. Which HMI 12mm gland should I use for an armoured cable?
If the installation requires armour clamping, the HMI DC012 Double Compression configuration is the relevant HMI option because HMI specifies DC012 for armoured cables and describes its cone-and-ring arrangement as clamping the armour.
5. Can HMI SC012 be used with an unarmoured cable?
HMI lists its Single Compression range as suitable for armoured / unarmoured cables, so SC012 is the relevant 12mm Single Compression option. Cable OD, thread and installation conditions still need to be checked before selection.
6. What material is the HMI 12mm cable gland made from?
HMI specifies nickel-plated brass as the material of construction for its Single Compression and Double Compression cable-gland ranges.
7. What thread does the HMI SC012/DC012 use?
HMI lists the entry thread as BSC (British Standard Conduit thread) for both the Single Compression and Double Compression ranges.
8. Are accessories available for the HMI 12mm cable gland?
For the Single Compression range, HMI lists Earth Tag and Shroud as available on request. For Double Compression, HMI additionally lists Stop Plug and Reducer/Adaptor as available on request.
9. How do I choose the correct cable gland size?
Start with the actual cable outside diameter, then check cable construction, armouring, thread and environmental requirements. Do not select a gland purely from conductor size or the nominal gland-size label.
See the detailed Thunderbolt guide: What Size Cable Gland Do I Need for My Project?.
10. What happens if the wrong cable gland is selected?
An incorrectly selected gland can result in poor gripping, inadequate sealing, installation difficulty or incompatibility with the enclosure entry. The practical solution is to verify the cable OD, construction and thread before ordering.
