Open/Close Detection


Industrial wireless open/close sensors provide information on the status of doors, windows, cabinets, etc.  One of the most cost-effective sensor implementations utilizes a simple reed switch & magnetic contact.  Both devices are installed in close proximity to each other on the sides of a door or window; spatial separation forces the opening/closing of the reed switch, triggering an alarm when doors or windows are opened.
