Plastic connector REDEL SP

resinIP50IP68

Product Overview
The REDEL SP Series takes high-performance connectivity to the next level — combining lightweight strength, exceptional contact density, and an ergonomic, easy-to-handle design. Now enhanced with resin-free IP68 sealing, it ensures uncompromised protection in the most demanding conditions. Crafted from FDA-approved PPSU, the REDEL SP Series stands up to repeated sterilization, harsh cleaning agents, and demanding environments — delivering lasting reliability in medical robotics, diagnostic equipment, field instruments, and UAV systems. Its patented internal Push-Pull latching system guarantees secure, intuitive mating, while the modular insert design offers flexibility for evolving needs. REDEL SP — where Swiss precision meets proven endurance, ensuring safe and seamless performance wherever reliability matters most.

Engineered for reliability. Designed for confidence.

• Resin-free IP68 sealing: Watertight and dustproof when mated, no resins required.
• Patented internal Push-Pull: Protects designs and preserves system integrity against imitation.
• High contact density: Up to 22 contacts in Ø15.5 mm.
• Durable & reliable: PPSU construction, resistant to sterilization and harsh cleaning.
• Unique design: Flexible contact insert system.
• Reinforced mechanical shock resistance: Ensures exceptional durability and extended product lifespan.

Key Features

• Patented internal push-pull latching system
• Wide range of keying and colour coding for failsafe set-ups in critical environments
• Strong blind mating using 3 guided keys
• RoHS compliant / UL Recognition
• For cable range from ø 2.5 mm to ø 7.5 mm
• IEC60601-1: qualified for ESD (15kV)
• Made of PPSU (polyphenylsulfone) for increased resistance to sterilisation

Main Applications

• Medical: Portable or mobile diagnostic devices, laboratory equipment handling sensitive fluids or gases, water purification or filtration systems, food and pharmaceutical applications cleaned with high-pressure washing, medical robots or sensors operating in clean environments.
• Test & Measurement: Outdoor test benches in uncontrolled industrial environments, embedded testing, temporary field sensors.
• UAV / Drones: Designed for weight-sensitive missions and harsh environmental conditions — offering protection against weather, dust, and splashes (IP68), along with reliable performance and superior shock resistance.

Cable Assembly Expertise
In medical environments, precision, reliability, and compliance are non-negotiable. Achieving a perfectly sealed IP68 solution is not just about the connector—it requires advanced cable solutions and cabling expertise that only LEMO can provide.

• Custom medical-grade cables: BioCompatic® designed for flexibility, biocompatibility, sterilization resistance, and signal integrity.
• Cable Assembly & Integration Services: Breakthrough sealing technology uses a cable clamping kit, eliminating traditional potting or resin-based processes that can be incompatible with strict medical regulations. The result is a robust, repeatable, and fully compliant solution that simplifies assembly without compromising safety or performance.

Cable Assembly Key Benefits
