Flexible Metal Hoses for Optoelectronics

Light conductors are used in optoelectronics to transmit information. Highly flexible stripwound hoses protect the light conductor from mechanical damage. Lining the inside of the flexible metal hose with silicone or a similar material allows autoclavable, light- and fluid-tight light conductors to be manufactured.

  • smallest outer diameters from approx. 1.4 mm with 0.35 mm interior coil
  • highly flexible, with bending radius limitation
  • high tensile strength and very small elongation
  • autoclavable, light-proof and liquid-tight

Endoscopy Hoses for Medical Technology

With an inner diameter of 0.3 mm, the protective hoses allow examinations to be conducted in the body. These highly flexible stripwound hoses from Witzenmann are light-proof and liquid-tight and meet the strict U.S. regulations according to Pharmacopoeia Class VI and are classified as biocompatible in accordance with DIN/ISO 10993 1-5.

  • small diameters for minimally-invasive medicine
  • suitable for autoclave sterilisation
  • particularly smooth and durable interior and exterior surfaces
  • certified biocompatibility

Special Bellows Materials for Measurement and Control Technology

In measurement and control technology, bellows elements are used as sensors and actuators. The main demands placed on sensors and actuators are that they lack hysteresis and feature a constant characteristic curve. To guarantee this, hardenable bellow materials are used.

  • thermostats as actuators
  • pressure switch
  • reduction or adjustment valves
  • sensors
