ABSTRACT:
A monitoring sensor for articles susceptible to theft, comprising a sensor element for monitoring a proper contact of the sensor with the article and a connecting cable for connecting the sensor to a monitoring circuit of a theft protection system is proposed. During disconnecting of the proper contact with the article, the sensor makes available a measured variable, the alteration in which can be evaluated by the monitoring circuit as an alarm situation. To enable the sensor to be produced in a flat type of construction and also to be easily connected to curved surfaces of an article to be protected, the sensor and the sensor element are of a flexible design, whereby any alteration in shape during disconnecting of the proper contact between sensor and article results in an alteration in the shape of the contact surface element and in an alteration in the measured variable.
