  • Membrane cable entry plate with cones | for 216×84 mm cut-out | 25 cables Ø5–26 mm | grey | IP65 / IP55 | HT Hi Tech Polymers | HTKC-25

    Code: Sandariklis HTKC-25

    HTKC-25 is a membrane cable entry plate with cones for a 216×84 mm cut-out, for up to 25 cables from Ø5 to Ø26 mm. The main ranges seal to IP65, and the larger cones also have an inner range for thinner cables at IP55.

  • Membrane cable entry plate with cones | for 216×84 mm cut-out | 25 cables Ø5–26 mm | grey | IP65 / IP55 | HT Hi Tech Polymers | HTKC-25

    HTKC-25 is a TPE-SEBS elastomer plate for a 216×84 mm cut-out with 25 cones: one Ø20–26 mm, four Ø14–20 mm, sixteen Ø8–14 mm and four Ø5–7 mm. The larger cones are two-zone: the outer range seals to IP65, while the inner range accepts a much thinner cable (IP55).

    Key point:
    When cable diameters are not exactly known in advance – for example when refurbishing an old board – two-zone cones give a margin: the same cone takes both a thick and a thinner cable. The entry layout is the same as HTC-25, so these plates are interchangeable.

    How it works

    A 216×84 mm cut-out and Ø10 mm fixing holes (spacing 193 × 62 mm) are made in the enclosure and the plate is screwed to the wall.

    The cone is cut to the cable's outer diameter: at the outer step for the main range (IP65), at the inner ring for a thinner cable (IP55).

    Each cable is sealed in its own cone; unused cones stay closed as reserve.

    Why choose HTKC-25?
    One plate covers a wide cable range from Ø5 to Ø26 mm, and the two-zone cones let you adapt flexibly to the actual cable diameters on site.

    Main functions

    • Two-zone cones – the same cone suits a thicker (IP65) and a thinner (IP55) cable
    • 1 cone Ø20–26 mm – for the board supply cable
    • 4 cones Ø14–20 mm – for sub-feeder or larger load cables
    • 16 cones Ø8–14 mm – for circuit cables
    • 4 cones Ø5–7 mm – for thin control or communication cables

    Where is it used?

    • Refurbishment of old boards with mixed cable diameters
    • Main boards in houses and terraced homes
    • Distribution boards in small commercial premises
    • Boards in outbuildings and garages
    • Outdoor cabinets next to buildings
    • Temporary and construction site boards

    Use by need

    For refurbishment electricians.
    Two-zone cones allow existing, previously unmeasured cables to be sealed without extra glands.
    For panel assemblers.
    The universal layout suits most small distribution boards, and HTKC-25 and HTC-25 are interchangeable.
    For facility managers.
    When a cable is replaced with one of a different diameter, the inner range of the same cone is often enough.

    Practical application

    If a refurbished house board keeps an old Ø24 mm supply cable and gets 3 new Ø16–18 mm cables for a heat pump and cooker, 14 circuit cables Ø9–12 mm and 2 thin Ø6 mm communication cables, HTKC-25 takes them all at IP65 and the remaining cones stay in reserve.

    Pros

    • Wide cable range – Ø5–26 mm
    • Two-zone cones – flexibility during installation
    • Interchangeable with HTC-25 (same layout)
    • Operating temperature −40…+130 °C
    • Halogen-free material for indoor and outdoor use

    Cons / limitations

    • In the inner range sealing is only IP55 – where IP65 is required, the cable must match the outer range
    • Only one cone above Ø20 mm; for several thick cables use HTKC-28
    • For many thin cables HTKC-50 is a better fit
    • Does not provide strain relief and is not a fire barrier

    Safety and installation notes

    • Work in the board with the power off and absence of voltage verified.
    • Remove swarf after making the cut-out.
    • Decide which range you will use before cutting – a cone cut too deep will no longer seal the outer range.
    • Secure cables inside the board.

    Quick selection guide

    Cut-out 216×84 mm
    Ø5–26 mm, up to 25 cables
    Two-zone cones
    IP65 / IP55, −40…+130 °C
    Suitable when you need:
    • cables of various sizes into a small board
    • flexibility when cable diameters are not known in advance
    • an equivalent replacement for HTC-25
    Check before use:
    • which cables fall into the main (IP65) and which into the inner (IP55) range
    • whether IP65 is required for the whole entry
    • that there is no more than one thick cable (above Ø20 mm)
    Important reminder: The inner cone range provides only IP55 – where the board needs IP65, choose cables to the outer range; the plate is not a fire-stop seal.

    FAQ

    What do the double ranges, e.g. Ø20–26 / Ø12–15 mm, mean?
    The larger range seals to IP65, the smaller inner ring takes a thinner cable at IP55.
    Are HTKC-25 and HTC-25 the same?
    No – these are products of different construction: the manufacturer describes HTKC-25 as a diaphragm (membrane) inlet flange and HTC-25 as an inlet flange. The 216×84 mm cut-out, fixing and cable ranges are the same, so one can replace the other when mounting.
    How many cables fit?
    Up to 25: 1 × Ø20–26, 4 × Ø14–20, 16 × Ø8–14 and 4 × Ø5–7 mm.
    Is it suitable outdoors?
    Yes, the material is intended for indoor and outdoor use, operating temperature −40…+130 °C.
    What if a cone has been cut too deep?
    Use it for a thicker cable or replace the plate – an oversize opening will not seal.
    Do cables need to be secured?
    Yes, the plate does not provide strain relief, so secure cables inside the board.
