DOUBLE SHEET DETECTOR
Scope: The Contrinex Double Sheet Detector utilizes our patented Condet technology to effectively discriminate
between one and two sheets of steel of defined thickness. This discrimination aids in the prevention of double feeds into blanking and forming processes which ultimately saves damage to tooling.

Installation & Setup Procedure:
Initially a suitable mounting location and means for mounting must be established. This location should be capable of placing the face of the sensor within approximately .250” - .375” from the path of the sheet metal travel. As all adjustment is by means of mechanical movement of the sensor with respect to the plane of the sheet metal, adequate space must be accounted for. A plastic threaded spacer is provided for convenience of establishing this spacing. Following mounting, present a double sheet situation to the sensor in such proximity to cause the output to energize and in turn de-energize when the second sheet is removed and only a single sheet is in the sensing area. Adjustment of the sensor nearer and further from the target is made by movement of the jam nuts and when a successful scenario is reached, lock down the sensor and proceed with the appropriate control scheme.
Experimentation is the best teacher of this procedure and is easily mastered outside the actual application prior to final installation.
