blueglobe PC HT Ex – The New Plastic Cable Gland for Hazardous Areas

PFLITSCH expands its trusted blueglobe cable gland range with the PC HT Ex e, a high-performance plastic gland specifically designed for increased safety (Ex e) applications in hazardous areas. Certified for use in Ex Zone 1 and 2 (gas) and Zone 21 and 22 (dust), the blueglobe PC HT Ex e ensures secure cable entry with exceptional strain relief and sealing.

Constructed from robust polycarbonate (PC), it offers high mechanical strength and long-term UV resistance. The HT (High Temperature) variant extends application potential by tolerating elevated temperatures, making it suitable for demanding industrial environments, including chemical, petrochemical, and offshore sectors.

 

Like all blueglobe cable glands, the PC HT Ex e features the unique blue sealing insert, which provides uniform sealing pressure and protects cable sheathing from damage. It supports a wide clamping range while ensuring IP66/IP68 protection.

 

A lightweight, corrosion-resistant, and cost-effective solution, the blueglobe PC HT Ex e offers safe and reliable performance where metal glands may not be necessary or feasible.

Product specifications at a glance

  • Material: Screw fitting body made of polycarbonate (PC), sealing inserts made of silicone
  • Certified safety: Suitable for two main areas of application:
  • Ex e area: Applications in explosion-protected environments that require increased safety.
  • Ex i area: Intrinsically safe circuits in which the limitation of electrical energy reliably prevents ignition hazards.
  • To differentiate between Ex e and Ex i circuits, the pressure screws are in grey and black or blue versions.
  • Protection class: IP66 and IP68 (10 bar, 60 min.)
  • Temperature resistance: Operating temperature range from -20 °C to +60 °C.
  • Sealing range: Flexible application options for cable diameters from 6.0 mm to 32.0 mm (depending on thread size).

Advantages of the PFLITSCH cable gland blueglobe PC HT Ex e

 

The new PFLITSCH Ex cable gland made of plastic offers several advantages:

 

  1. Weight: it is significantly lighter than metallic alternatives, which is particularly advantageous in applications with weight restrictions (e.g. portable devices or installations at lofty heights).
  2. Corrosion resistance: Plastic is resistant to rust and other forms of corrosion, which increases the life of the fitting in humid or aggressive environments.
  3. Insulation properties: Plastic inherently provides high electrical insulation, which can eliminate the need for additional safety measures.
  4. Value for money: Plastic solutions are more cost-effective to manufacture, while still offering high performance and reliability.

 

 

 

Target industries and applications

 

The blueglobe HT Ex e cable gland is versatile and offers a safe and reliable solution for various applications in potentially explosive environments. Possible applications:

 

Chemical and petrochemical plants:

Safe connection of control and supply cables in potentially explosive atmospheres, such as pumps, agitators or control systems.

Prevents the ingress of gases or moisture into control boxes and Distribution enclosures.

 

Pharmaceutical production facilities:

Integration in machines where potentially explosive dusts (e.g. when processing powders) can occur.

 

Food industry:

Installation in filling systems or mixing machines that are operated in potentially explosive atmospheres and require a high level of protection against moisture and dust.

 

Oil and gas industry:

Use in control systems on oil platforms, in refineries or in tank farms where Ex e and Ex i protection is equally required.

 

Battery storage and renewable energies:

  • Protection of Cable entries and transits in battery storage systems where low energy levels need to be controlled.
  • Applications in potentially explosive areas of biogas plants.

 

Sensors and measurement technology in hazardous areas:

Installation in sensitive environments where devices for measuring temperature, pressure, or humidity are operated.
