7 reasons it’s top choice for medical device manufacturers

“Autoclavable and sterilization-proof, IP68 watertight, low-friction, and built to our exact specs – Fischer’s silicone overmolded cables simply outlast the competition. That reliability translates directly into longer device service life.” – Reported by Katlyn Grella, Medical Key Account Manager, Fischer Connectors USA

Reliability and longer device service life aren’t marginal benefits in medical devices. They’re the difference between a cable that gets replaced and a cable that clinicians never have to think about.

Engineered for performance, proven worldwide

Fischer Connectors’ overmolded cable assemblies are trusted by medical design manufacturers around the world for devices and systems used in Diagnostic & Imaging (endoscopy, laparoscopy) and Interventional & Surgical applications.

Their strongest differentiators come from a combination of factors: medical-grade overmolding with the flexibility to give surgeons the most ergonomic solution during operations, sterilization resistance validated for autoclave, and consistently high quality – backed by the Fischer team’s expertise in connectors, responsiveness, and customization, down to machined parts, contact configuration, and cable construction.

Seven reasons medical device manufacturers choose Fischer Connectors

The feedback we’ve received from our medical key account managers worldwide points to a combination of reasons why medical device manufacturers choose Fischer Connectors over the competition. Here are seven of them:

Superior sterilization resistance. Fischer Connectors’ silicone overmolded cable assemblies are designed to withstand repeated sterilization processes, including steam autoclave, high temperatures, disinfectants, and sterilant solutions. Silicone insulation offers a very wide operating temperature range, from -60°C to +180°C, suited to reusable medical devices exposed to aggressive cleaning cycles. The result: longer cable life and lower replacement costs in operating rooms, surgical robotics, monitoring systems, and diagnostic equipment.

High durability at the connector-to-cable transition. The overmolds and heat-shrink solutions are engineered for sealing up to IP68/IP69, abrasion resistance, impact resistance, vibration damping, and protection against fluid ingress. This transition zone is often the most failure-prone part of a cable assembly, which is why Fischer specifically engineers it for demanding medical environments – improving reliability and reducing field failures.

Better cable handling and user experience. Soft silicone overmolding combined with custom geometries improves flexibility, tactile feel, cable management, resistance to kinking, and ease of cleaning. Fischer also designs compact, lightweight connectivity solutions for portable and wearable medical devices – translating directly into a better experience for clinicians and patients.

Medical-focused design and certification. Fischer Connectors is ISO 13485 certified, the international quality management standard for medical devices, with compliance support for FDA-regulated equipment and connectivity solutions tailored to medical applications. Designs are built to meet IEC 60601-1 requirements for patient and operator protection (MOPP/MOOP) – making supplier qualification and regulatory documentation easier, and keeping patients and operators safe.

True system-level integration. Unlike many cable assemblers that purchase third-party connectors, Fischer Connectors designs the connector, the cable assembly, and the overmold as one system. This vertically integrated approach enables optimized performance, faster development, and better quality control from the connector interface to the finished assembly – reducing supply-chain complexity and technical risk for the customer.

Extensive customization capabilities. Custom silicone overmolds, custom geometries, custom colors, low-friction coatings, and tailored cable configurations mean customers aren’t forced into standard catalog products. Assemblies can be optimized around the specific requirements of the device – improving ergonomics, supporting branding consistency, and helping devices stand apart.

Proven expertise in harsh and mission-critical environments. Unlike some purely medical-focused competitors, Fischer Connectors brings expertise from medical, defense, industrial, robotics, and other harsh-environment applications. That heritage translates into ruggedness, sealing know-how, and long-term reliability that carries over directly into medical-grade cable assemblies.

The bottom line

Fischer Connectors’ silicone overmolded medical cable assemblies combine exceptional sterilization resistance, superior strain relief and sealing, ISO 13485-certified manufacturing, and full connector-to-cable integration, delivering longer service life and higher reliability in demanding medical environments. It’s the same combination medical key account managers hear from customers again and again: reliability engineered in from the connector to the cable, so it holds up procedure after procedure.
