Presair, a division of Senasys designs pneumatic control solutions for environments where electrical components cannot operate safely. MRI compatible switches provide a reliable way to control equipment without introducing electromagnetic interference that can disrupt imaging systems. These non-electric devices use pneumatic signals to activate controls, making them ideal for MRI rooms where safety, reliability, and compliance are critical.

MRI Compatible Switches for Patient Music Control Systems
MRI procedures often create stress for patients due to confined spaces and loud operating noise. Music systems help reduce anxiety during scans, and MRI compatible switches allow safe control of these systems without introducing electrical components near the MRI magnet.
The Presair B465 push button air bellow provides a simple pneumatic interface for controlling music playback during procedures. The push button connects to a Tinytrol Air Switch through pneumatic tubing and a 6418 bulkhead coupler, creating a fully non-electric control path.
When the push button is pressed, a pneumatic signal travels through the tubing to the air switch located inside the music control system. The air switch interprets the signal and activates functions such as starting, pausing, or adjusting music playback.
Key technical advantages include:
-
Non-electric operation that eliminates electromagnetic interference with MRI systems
-
Soft actuation that allows easy operation for both patients and technicians
-
Durable construction designed for repeated use in clinical environments
-
Reliable pneumatic signal transmission through the Tinytrol Air Switch and coupler assembly
This pneumatic control design allows patients to adjust music independently, improving comfort while allowing imaging staff to focus on the procedure.
MRI Compatible Switches for Emergency Shutdown Systems
Emergency shutdown systems in MRI rooms require reliable activation without introducing electrical components that could interfere with magnetic fields. Compatible switches provide a pneumatic alternative that maintains system safety while ensuring rapid emergency response.
The Presair Soft Push Button Air Actuator (B900g) functions as a pneumatic emergency shutdown trigger. The actuator connects to a pneumatic tubing system that links directly to the MRI system’s emergency stop or alert mechanism.
When pressed, the actuator sends a pneumatic signal through the tubing to activate the shutdown or alert function. This design removes complex wiring and prevents electromagnetic interference within the MRI environment.
Key technical features include:
-
Non-electric design that eliminates EMI risk in MRI rooms
-
Low actuation force for quick activation in high-stress situations
-
Non-metallic construction compatible with MRI safety requirements
-
Durable design built for continuous use with minimal maintenance
This pneumatic shutdown actuator improves safety protocols by providing a reliable and accessible emergency control mechanism for staff or patients.
MRI environments demand control systems that operate without electrical interference while maintaining reliability and safety. MRI compatible switches from Senasys provide a practical pneumatic solution for applications such as patient comfort systems and emergency shutdown controls. By using air-powered push buttons and actuators, healthcare facilities and equipment manufacturers can implement dependable control interfaces that meet MRI safety requirements while supporting efficient clinical workflows.
