FAQs
What does IP66 protection mean?
IP66 means the gland is dust-tight (6) and protected against powerful water jets (6), making it suitable for very harsh environmental conditions.
Is this gland suitable for all explosive atmospheres?
It is certified for explosive gas atmospheres (II 3G Ex ec IIC Gc) in Zone 2 and explosive dust atmospheres (II 3D Ex tc IIIC Dc) in Zone 22.
What is the maximum cable diameter this gland can accommodate?
The gland is designed to seal cable diameters ranging from Ø10mm to Ø17mm.
Can I use this gland in very cold or hot environments?
The gland is tested for temperatures from -60°C to +85°C, but the specified operating temperature range is -20°C to 40°C. Ensure your application's continuous operating temperature falls within this narrower range.
What material is the gland made of?
It is constructed from weather-resistant, halogen-free polycarbonate (PC).
Does the gland include a lock nut?
Yes, the gland includes a lock nut to secure it to the enclosure.
What is the thread size and length?
The thread size is M25, and the thread length is 10 mm.
Troubleshooting
Gland does not seal properly around the cable.
Verify the cable diameter is within the specified sealing range of Ø10-17mm. Ensure the gland cap is fully tightened onto the cable.
Difficulty fitting gland into the enclosure hole.
Confirm the bore diameter is exactly Ø25.2mm. Check if the enclosure wall thickness exceeds the 3mm maximum limit.
Reduced strain relief performance.
Ensure the gland's cap is tightened sufficiently to grip the cable effectively. Check that the cable is not excessively stiff or has sharp bends near the gland.
Gland shows signs of degradation in extreme temperatures.
While tested up to 85°C, the operating range is -20°C to 40°C. Ensure the gland is not consistently exposed to temperatures outside its specified operating range for long durations.
Pros and Cons
Pros
- High level of safety with certifications for explosive gas and dust environments.
- Excellent protection against environmental factors with IP66 rating.
- Robust construction suitable for extreme temperatures and demanding conditions.
- Built-in strain relief adds to cable longevity and connection security.
- Halogen-free material promotes safer working conditions.
Cons
- Specific sealing range (Ø10-17mm) requires careful cable selection.
- Maximum wall thickness of 3mm may limit certain installation scenarios.
- Operating temperature range (-20°C to 40°C) is narrower than the storage/testing range, requiring attention for applications near temperature limits.
Setup, Compatibility & Care
Setup:
- Ensure the enclosure or mounting surface has a Ø25.2mm bore hole.
- Insert the cable through the gland, ensuring it is within the Ø10-17mm sealing range.
- Slide the gland into the bore hole. The maximum wall thickness for the enclosure is 3mm.
- Place the gasket ring on the outside of the enclosure.
- Secure the gland using the provided lock nut. Tighten firmly using a 30mm wrench.
- Tighten the cap of the gland onto the cable to create a seal and provide strain relief.
Compatibility:
- Thread Size: M25
- Cable Diameter Range: Ø10mm to Ø17mm
- Enclosure Wall Thickness: Up to 3mm
- Hazardous Zones: Ex 2, 22 (Gas & Dust)
Care:
- Periodically inspect the gland for any signs of damage or wear, especially after extreme environmental events.
- Clean the exterior with a damp cloth. Avoid using harsh chemicals or abrasive cleaners that could damage the polycarbonate material.
- Ensure the gland remains securely tightened. Loose fittings can compromise the IP rating and safety certifications.
