Reed Sensors in Mobility Equipment and Hospital Beds

Reed Sensors in Mobility Equipment and Hospital Beds

Reed Sensors Are Ideal for Sensing so called "End Positions" On Hospital Beds And Other Mobility Equipment eg; motorized chairs, special lifts for bath tubs, massage chairs, etc. all require end position detection. Since all these can be operated by the consumer, care needs to be taken to use low power switching devices, thus eliminating the threat of electrical shock to the user. Also dust, dirt, and moisture may be present, with potential spillage occurring. All of the aforementioned could create faulty operation of switching devices. Mechanical limit switches have been used in the past, but can fail prematurely, because they require higher switching power to operate properly.

Designers have now turned to the Reed Sensor which uses hermetically sealed reed switches, which are ideal for switching low signal levels reliably. If the motion is very complex, combinations of Reed sensors and magnets may be used effectively to accomplish desired detections.

Features
• The reed switch used in the Reed Sensor is hermetically sealed and is therefore not sensitive to spillage or wet environments
• The hermetically sealed reed switch is ideally suited for switching low signal level voltages and currents
• Magnet and Reed Sensor are isolated and don't need physical contact
• The magnet is not affected by its environment
• Millions of reliable operations
• Cylindrical hole and screw fastening mounting
• Contacts dynamically tested
• Large sensing distances possible

Applications
• Sensing end position(s)
• Medical mobility equipment
• Hospital beds
• Applicable in dirty and/or wet environments
• Lift chair position
• Mobility scooter
• Patient lift
• Power wheelchair
• Stair lift position
• Wheelchair ramp position
