LEMO has introduced the REDEL SP IP68 Series, a new family of compact circular connectors designed for medical equipment, test and measurement devices, and unmanned aerial systems. The series provides IP68-rated sealing without the use of resin or potting compounds, aiming to simplify assembly while maintaining environmental protection and mechanical durability.
The connectors use a resin-free sealing structure that provides protection against water and dust when mated. Housings are made from PPSU, an FDA-certified polymer known for resistance to repeated sterilization, cleaning agents, and harsh operating environments. The design incorporates LEMO’s internal push-pull latching mechanism and a flexible insert system for both plugs and receptacles. With up to 22 contacts within a 15.5-mm diameter, the connectors provide high contact density for space-limited designs.
Mechanical features include reinforced shock resistance and construction intended for long-term wear. The resin-free sealing approach is intended to reduce assembly steps and improve consistency while retaining watertight performance.
LEMO notes that achieving full IP68 protection also depends on cable selection and assembly practices. The company offers BioCompatic medical-grade cables and cable-clamping solutions designed to maintain sealing performance, signal integrity, and sterilization resistance. Complete assemblies are produced under ISO 13485 manufacturing processes.
The REDEL SP IP68 Series is available globally through LEMO and authorized distributors.
