What is the Pemsa collection?
Pemsa groups conduit and sealing accessories for cable entries in panels and boxes: cable glands, nuts, and fastening elements that ensure sealing, mechanical retention, and cable management in solar and electrical installations. Its approach is technical-professional, with resistant materials and certified protection ratings.
Advantages and limitations
- Sealing up to IP68 in selected models for humid or dusty environments.
- Compatibility with PG and metric threads (e.g., PG21), covering defined cable diameters.
- Technical materials (polyamide, metal) with good chemical and mechanical resistance.
- Quick installation from the outside, with inner nut and sealing gasket.
- Limitations: select the appropriate Ø range and IP rating; an inadequate choice may compromise protection.
Applications
- Cable entry in electrical panels and enclosures.
- Conduit in photovoltaic systems: routing of solar cable and DC/AC wiring.
- Industrial installations, light marine and outdoor applications with sealing requirements.
How to choose the right accessory
- Thread: PG (e.g., PG21) or metric (M16, M20…). Must match the enclosure's hole.
- Clamping range: cable diameter (e.g., Ø13–18 mm) to ensure retention and sealing.
- IP rating: IP66/67/68 depending on exposure to water/dust.
- Material: polyamide for lightness and insulation; metal/stainless steel for high temperature or chemical aggression.
- Accessories: compatible nuts and gaskets; check tightening pressure specified by the manufacturer.

The data are typical ranges; check each datasheet to confirm exact values and compatibilities.
Installation Best Practices
- Select the cable gland by cable Ø range, not just by thread size.
- Respect the tightening torque and use gaskets to achieve the indicated IP rating.
- Avoid excessive bending radii and protect the edges of perforations.
