Marl has announced a new LED panel indicator lamp, sealed to IP68 for tough, wet and dirty environments including marine and industrial applications. The new product works at pressures up to 10psi and is protected against corrosive fluids, as well as against shock and vibration.
The Marl 665 series features a hard black anodised aluminium housing, a domed, shatterproof polycarbonate colour diffused lens assembly and IP68 sealed enclosure, as well as a PTFE ‘top hat’ design panel seal. The indicator features a hexagonal bezel to aid mounting, and a range of high intensity sunlight readable LEDs is offered in red, yellow, green, blue or white. Internal circuitry is designed to operate at 2Vdc-20mA. Terminations are achieved by 150mm of colour-coded flying leads.
Key features include the self-lubricating PTFE seal ensuring indicator centralisation and the internal potting medium, which is cured under vacuum to ensure no air voids are present within the indicator assembly. Mean Time Between Failure for this family is over 100,000 hours. The indicator comes complete with full mounting hardware. Future developments include a voltage range up to 75Vdc, smoked lens assembly for exceptional on/off contrast ratio and alternative housing materials to suit bespoke applications.
