Waterproof Glands






Waterproof glands:
Index Marine makes glands for a range of sealed cabling applications where a weatherproof seal is required for electrical cables and ducting through bulkheads and panels:
IP68 rated ; Single and multi-cable pass-through – range of cable diameters
Perpendicular (DG series) and side-entry (SE series) cable positions
Stainless steel, aluminium and coloured plastic finish options
SE Series – side-entry cable pass-through
The SE series side entry cable gland is the perfect solution when space is limited or when loops from conventional top entry glands are not appropriate. The entire SE series of glands are tested achieving the IP68 rating which ensures a perfect waterproof solution for various cable management applications. Each unit is supplied with clear fitting instructions and A4 stainless steel fixings. The tapered seal ensures that the hole closes completely, creating a watertight seal around the cable. Ideal for electrical cabling applications and ducting through bulkheads, decks, and panels – i.e. VHF, Satnav, GPS and Radar installations.
Finishes available: black plastic, grey plastic and white plastic.
SE1: Preformed bungs included for pass-through suitable for cable sizes 2-7mm
SE5: Preformed bungs included for pass-through suitable for cable sizes 7-9mm
SE6: Preformed bungs included for pass-through suitable for cable sizes 7-9mm
SE7: Preformed bungs included for pass-through suitable for cable sizes 2 x 3-6mm

IM2200 – Electrical status/fault indicator – Provides a monitoring LED light panel, which can indicate problems with the vessels’ earthing system and any AC or DC fault conditions alerting you to shut down electrics immediately and seek a professional electrician for advice.
Safety electronic systems – alarm and control panels
BE10 pump control panel – When coupled with BE51/BE55 optical and resistive fluid sensors, float switches and capacitance level sensors, the BE10 Electronic Pump Control Unit provides automatic pump running to ensure there is no dangerous build up of water or fluids, making it ideal for use in working boats as well as land-based applications where water ingress is a problem.
BE15 4 station bilge alarm – A rugged and straightforward solution to alerting users of working, military and special use boats to the presence of water in the boat’s bilges, the BE15 is a sealed unit that is easy to install, and provides reassurance on busy active boats.
BE16 4 station alarm panel – general purpose – Monitoring up to 4 zones and compatible with Index Marine BE51/BE55 optical and resistive fluid sensors as well as third party sensor types, the BE16 offers low power consumption for indoor stations monitoring water level and other inputs. It is ideal for use in building and infrastructure flood alert systems.
BE18 waterproof 4 station alarm panel – Ruggedised and splashproof, the BE18 monitors up to 4 zones and can be used with BE51/BE55 optical and resistive fluid sensors as well as third party sensor types to alert to any combination of water ingress, gas presence, hatch and door security, or many other sensor inputs. This is a robust, versatile alarm panel that serves a wide range of uses in boats, vehicles, architectural and industrial applications.
BE20 – water ingress alarm – dual station level alarm – Designed to monitor high or low levels of liquids, the BE20 has two channels with audio alarm and independent annunciator lights. It is ideal for monitoring water ingress in boat bilges and compartments, and buildings and infrastructure in flood-prone areas.
