    RIT-50 is a 330×90 mm membrane cable entry plate for Rittal-type openings. 50 cones in five groups: 2× Ø19–34, 4× Ø16–25, 2× Ø15–21, 26× Ø10–15 and 16× Ø6–11 mm. Rated IP65, fixed with 8 screws through Ø4 mm holes.

  • Product description

    Membrane cable entry plate | for Rittal-type opening | 330×90 mm | 50 cables Ø6–34 mm | grey | IP65 | HT Hi Tech Polymers | RIT-50

    RIT-50 is a medium-size membrane plate for Rittal-type cable entry openings, used when a cabinet receives a mixed set of cables: a few power cables, many control cables and thin sensor cables. Each cable enters through its own cone, which is opened only when needed.

    Key point:
    Five size groups from Ø6 to Ø34 mm let one plate close the whole entry of a typical automation or building services cabinet. There is no need to collect separate glands for every diameter – you only need the outer Ø and the number of cables.

    Protection
    IP65

    How it works

    The plate is placed over the Rittal-type opening and fixed with 8 screws through Ø4 mm holes, pressing the sealing edge against the enclosure.

    Each cable is given a cone of the right group, cut at the step slightly smaller than the cable's outer Ø – the TPE-SEBS membrane wraps tightly around the sheath.

    The cabinet entry is sealed to IP65, unused cones stay closed as a reserve.

    Why choose RIT-50?
    RIT-50 covers a wide range of diameters: from thin Ø6 mm sensor or data cables up to Ø34 mm power cables. This is convenient in cabinets with very different cables and limited space for the entry.

    Main functions

    • Five cone groups – Ø6–11, Ø10–15, Ø15–21, Ø16–25 and Ø19–34 mm in one plate
    • 16 openings for thin cables – Ø6–11 mm for sensors, data and alarm lines
    • 2 openings up to Ø34 mm – for power cables without a separate gland
    • Reserve without blanking plugs – uncut cones stay sealed
    • IP65 and −40…+100 °C – for indoor and outdoor cabinets

    Where is it used?

    • Automation cabinets for building services (HVAC, lighting)
    • Machine and equipment control cabinets in Rittal-type enclosures
    • Control panels of pumping stations, boiler rooms and heat substations
    • Combiner and control cabinets of solar power plants
    • Floor distribution boards with power and low-current cables
    • Outdoor control cabinets requiring an IP65 entry

    Use by need

    For the automation designer.
    One item covers a mixed cable set from Ø6 to Ø34 mm – a simpler specification and fewer gland types.
    For the electrician.
    No drilling and threading for every cable – just cut the cone of the right group.
    For the building manager.
    When a sensor or device is added, its cable goes through a spare cone without changing the enclosure.

    Practical use

    If an HVAC automation cabinet needs 2 power cables Ø24 mm, 4 cables Ø20 mm, 18 control cables Ø12 mm and 10 sensor cables Ø8 mm, 34 cones are cut and 16 remain as a reserve for sensors or actuators added later.

    Pros

    • 50 cables through one opening
    • Wide range Ø6–34 mm
    • 16 openings for thin cables Ø6–11 mm
    • IP65 according to EN 60529
    • Halogen-free TPE-SEBS, −40…+100 °C
    • Fixed with 8 screws

    Cons / limitations

    • There is no opening for a cable thicker than Ø34 mm – choose RIT-139 (1× Ø30–60 mm)
    • Only 2 openings Ø19–34 mm and 4 openings Ø16–25 mm; more thick cables require a larger plate
    • The membrane does not provide strain relief – cables must be secured inside the cabinet
    • It is not a fire barrier

    Safety and installation notes

    • Switch off the voltage and verify its absence before working in the cabinet.
    • Use a separate cone for each cable and cut it at the step slightly smaller than its outer Ø.
    • Do not damage the membrane with sharp conductor ends when feeding cables – cover them with a cap or tape.
    • Remove swarf and dirt from the opening edges before fitting the plate.
    • Check that all 8 screws are tightened evenly – otherwise the edge may not seal.

    Quick selection guide

    Plate 330×90 mm
    8 holes Ø4 mm
    50 cables Ø6–34 mm
    IP65, −40…+100 °C
    Suitable when you need:
    • to bring a mixed cable set from Ø6 to Ø34 mm through one Rittal-type opening
    • to seal an automation cabinet entry to IP65
    • to leave a reserve for additional sensor cables
    Check before use:
    • that the enclosure opening fits a 330×90 mm plate with 8 fixing holes
    • how many cables fall into each Ø group – especially those above Ø16 mm
    • that no cable is thicker than Ø34 mm
    Important reminder: RIT-50 seals the entry (IP65) but does not protect the cable against pull-out and is not a fire barrier – secure the cables inside the cabinet and use certified systems in fire-rated walls.

    FAQ

    How many cables fit into RIT-50?
    Up to 50 cables Ø6–34 mm, each through its own cone.
    Which cable sizes are the openings for?
    2× Ø19–34, 4× Ø16–25, 2× Ø15–21, 26× Ø10–15 and 16× Ø6–11 mm.
    Can a cable thinner than Ø6 mm be used?
    No, the smallest group is Ø6–11 mm; for very thin cables there is HT-50 (Ø3.5–5.5 mm) for a Ø50 mm hole.
    How does RIT-50 differ from RIT-139?
    RIT-50 is smaller (330×90 mm, 50 cables Ø6–34 mm), RIT-139 is 534×149 mm with 139 cables Ø10–60 mm.
    How is the plate fixed?
    With 8 screws through Ø4 mm holes.
    What temperature range is it rated for?
    The manufacturer states an operating range of −40…+100 °C.
