Reed Sensors
Features
• Magnetically operated proximity
sensor
• Compact size requires only 3mm
diameter hole
• Hermetically sealed contacts
• Custom cable length and connector
options available
Benefits
• Well suited for usage in high-
moisture and contaminated
environments
• Non-contact solution, aesthetically
more appealing than push-button or
lever mechanical-type switches
• Simple installation and adjustment
• No standby power requirement
• Ideal for battery-powered
applications as the contacts do not
draw power when in the non-
activated state
• Reed contacts last for millions of
operating cycles under micro-
controller logic-level loads
Applications
• Position and Limit Sensing
• Security System Switch
• Level Sensing
• Linear Actuators
