TSP | Strain Relief Plastic Cable Gland For all types of Unarmoured & Braided / Screened Cables

The TSP polymer strain relief range of cable glands are suitable for use in industrial (safe) areas with unarmoured or braided cable when terminated inside the enclosure, and have a temperature rating of +100°c to -40°c.

With the widest cable sealing range on the market, the TSP reduces the need to purchase a range of different sized cable glands for a project, reducing the overall cost.

The TSP range meets the requirements of well-known cable gland standards including EN 62444 and IEC 62444.

For more specific applications IP68 & IP69X ingress discs or plugs are available, as well as a flame retardant UL94 V-0 option.

Features include:

  • Halogen and phosphorus free
  • Finger-locking seal provides superior cable retention & strain relief
  • 3rd party certified to IEC 62444 and EN 62444
  • Flame retardant UL94 V-0 version available
  • Low weight with high stiffness and strength
  • Widest cable range take for any comparable cable gland
  • Available in a variety of colours (black as standard, see table to the left)
  • Anti-vibration technology prevents gland loosening in operation
  • Transit disc or IP68, IP69 & IP69K rated IP plug options available
  • Approved entry thread sealing washer included
  • Polyamide locknut available (ordering suffix 2TN) – delivered assembled

Tightening tools may be required to aid installation. For further information, please click here.

BS 6121-1:1989 vs IEC 62444 / EN 62444

Whilst new standards such as IEC 62444 and EN 62444 have more recently been introduced, which CMP Products fully complies with, BS 6121-1:1989 still remains a very important benchmark for users and manufacturers around the world, due mainly to the fact that it is a more onerous construction standard than others published. This will therefore be especially relevant where a national cable gland standard isn’t available. The tables below show the maximum cable entry bore size and tolerances permitted through the range of BS 6121-1:1989 cable gland sizes.

Protection by Enclosure Against Mechanical Impact

It is critically important that enclosures afford a level of mechanical protection relevant to the area of installation that provides optimum electrical and operational safety. The international standard IEC 62262 covering ‘Degrees of protection provided by enclosures for electrical equipment against external mechanical impacts (IK Code)’ outlines the requirements for testing and rating of enclosures of different materials, so that careful selection to suit the application can be achieved.
