In the high‑stakes world of healthcare, where precision, uptime, and safety can determine clinical outcomes, the infrastructure supporting medical technology must be nothing short of flawless. From life‑sustaining monitoring systems to robot‑assisted surgical platforms, modern medical devices depend on connectors that perform reliably under constant mechanical, electrical, and environmental stress.
For more than 75 years, LEMO and its medical‑focused brand REDEL have built a global reputation for precision interconnect solutions. With a portfolio exceeding 75,000 modular connector configurations, LEMO has become a cornerstone supplier to medical OEMs worldwide—supporting applications across diagnostics, imaging, surgical robotics, patient monitoring, therapy delivery, and laboratory automation.
What sets LEMO apart is not only connector performance, but a systems‑level understanding of medical compliance, usability, and lifecycle reliability.
The REDEL Family: Engineered for the Clinical Environment
The REDEL connector family is purpose‑built for medical applications where ergonomics, patient safety, and sterilisation resilience are non‑negotiable. These connectors are instantly recognisable by their clean, modern aesthetic and Push‑Pull latching mechanism—an industry benchmark in medical device connectivity.
REDEL P Series – Lightweight, Proven, and Versatile
The REDEL P Series plastic Push‑Pull connectors are widely adopted across patient‑connected devices and portable medical equipment.
- Manufactured from high‑performance thermoplastics such as PSU (Polysulfone) and PEI (Polyetherimide)
- UL‑certified, self‑extinguishing materials for enhanced fire safety
- Supports up to 34 contacts, accommodating mixed signal and low‑power needs
- Rated for 5,000+ mating cycles, ideal for equipment subject to frequent reconnection
- Available in multiple sizes to balance contact density with ergonomic handling
These characteristics make the P Series particularly well suited to applications such as patient monitoring leads, diagnostic instruments, and compact therapy systems.
REDEL SP Series – Sealing, Density, and Sterilisation Endurance
The REDEL SP Series builds on the P Series foundation, adding robust environmental protection and higher integration capability.
- Patented internal Push‑Pull locking mechanism, fully protected from contamination
- IP68 sealing (when mated), safeguarding against fluids, dust, and cleaning agents
- Housings manufactured from PPSU (Polyphenylsulfone)—a material chosen for its exceptional resistance to repeated sterilisation
- High contact density: up to 22 contacts within a compact 15.5 mm shell
- Designed to withstand repeated autoclave cycles without mechanical degradation
This makes the SP Series especially suitable for surgical handpieces, reusable instruments, and clinical environments requiring aggressive cleaning protocols.
REDEL MP Series – Modular Plastic Connectivity Redefined
For highly complex medical systems, the REDEL MP (Modular Plastic) Series represents a step change in interconnect architecture.
- Utilises a Card Edge modular concept
- Supports up to 144 contacts in a single interface
- Enables the combination of:
- Power
- Low‑ and high‑speed signal
- Data (Ethernet, USB, SPE)
- Fibre optics
- Fluidic and pneumatic channels
By consolidating multiple transmission types into one connector, the MP Series reduces interface complexity, shortens setup time, and improves serviceability—key advantages in high‑value medical platforms such as robotic surgery systems, imaging gantries, and advanced therapy workstations.
Safety First: Supporting IEC 60601‑1 Compliance
Meeting IEC 60601‑1 (3rd Edition) is one of the most demanding challenges facing medical device manufacturers. LEMO connectors are engineered specifically to support compliance with this critical safety standard.
Electrostatic Discharge (ESD) Protection
Sensitive electronics and patient‑connected devices are protected through:
- ESD resistance up to 15 kV
- Controlled discharge paths that reduce the risk of latent electronic failure
- Enhanced system reliability in environments prone to static build‑up
MOPP and MOOP Design Support
LEMO offers connector inserts with qualified creepage and clearance distances, enabling designers to achieve:
- Means of Patient Protection (MOPP)
- Means of Operator Protection (MOOP)
These features simplify risk assessment and help accelerate regulatory approval during device certification.
Finger‑Safe Geometry
Connector safety does not end at electrical performance. The geometrical design of REDEL inserts prevents finger access to live contacts when unmated, satisfying finger test requirements and reducing the risk of accidental electric shock during handling or maintenance.
Sterilisation and Material Excellence
Medical connectors must endure far more than electrical load—they must survive relentless cleaning and sterilisation cycles without compromise.
LEMO selects materials such as PPSU and PEEK for their:
Long‑term mechanical and dimensional stability
Exceptional resistance to steam autoclave sterilisation
Compatibility with ETO and Gamma radiation
Long‑term mechanical and dimensional stability
BioCompatic™ Cables – Designed for Patient Contact
Complementing the connector ecosystem, LEMO BioCompatic™ cables are engineered specifically for medical use:
- Biocompatible and patient‑safe
- Free from bisphenol, phthalates, and latex
- Highly flexible with excellent torque and bend resistance
- Rated for up to 500 steam autoclave cycles
- Optimised for long service life in dynamic medical environments
This integrated connector‑and‑cable approach ensures consistent performance across the entire interconnect system.
Intelligent and Hybrid Connectivity
HALO LED – Visual Intelligence at the Interface
LEMO’s HALO LED connectors introduce intelligent feedback directly at the point of connection.
- Integrated RGB LED illuminated flange
- Provides instant visual confirmation of:
- Connection status
- Operational state
- Error or alert conditions
In fast‑paced surgical or emergency environments, this visual feedback reduces setup time, minimises errors, and enhances overall workflow efficiency.
Hybrid Medical Umbilicals
Modern medical systems increasingly demand hybrid transmission. LEMO excels in delivering connectors and assembled umbilicals that integrate:
- Low‑voltage power
- High‑speed data (USB 2.0, Ethernet, Single Pair Ethernet)
- Fibre optics
- Fluidic channels for air, suction, or inert gases
By reducing the number of external cables, these solutions improve ergonomics, reduce clutter, and simplify cleaning—especially critical in operating theatres and ICU Environments.
LEMO as a Total Medical Connectivity Partner
LEMO’s value extends far beyond individual connectors. As a full solution partner, LEMO supports medical OEMs from concept to production.
- ISO 13485‑certified manufacturing facilities
- Complete cable assembly services
- Custom overmolding for strain relief, sealing, and branding
- Collaborative engineering support for system optimisation
- Rapid prototyping through to high‑volume production
This end‑to‑end capability allows medical device manufacturers to reduce supplier complexity, shorten development cycles, and focus on delivering innovation to clinicians and patients.
Enabling Better Outcomes Through Reliable Connectivity
In medical technology, reliability is not optional—it is foundational. Through decades of innovation, rigorous quality control, and deep regulatory expertise, LEMO and REDEL connectors continue to enable safer, smarter, and more connected medical devices.
By combining mechanical excellence, electrical performance, and human‑centred design, LEMO ensures that healthcare professionals can focus on what matters most: delivering exceptional patient care.
