Create Double-Sheet Sensors Using Contrinex SMART Sensors and PocketCodr
Contrinex SMART inductive sensors can quickly & easily be configured as Double-sheet detection sensors using the PocketCodr module & companion app. Monitoring & configuration of the sensor is done on a tablet or phone. removing the need for any coding.
Contrinex's SMART inductive sensors and the innovative PocketCodr sensor configurator offer flexible and highly reliable double-sheet detection solutions for a manufacturer of pressed-metal parts.
The compact yet robust, metal-bodied M18 sensors are located on either side of the conveyor which feeds the metal blanks to the press. Not only do they sense the presence of each sheet, allowing the press operation to be initiated automatically, but they also detect an unwanted double-sheet condition, triggering an alarm before damage occurs.
PocketCodr puts the monitoring and configuration of the SMART sensor into the hands of the engineer on a tablet or phone and removes the need for any coding. After configuring the sensors, the technician connects it directly to the PocketCodr device with the supplied cable and uses the companion app installed on a tablet to set and monitor the sensor’s switching points.
As a metal sheet passes the sensor, the measurement value is displayed together with the high/low status of the two internal switching signals (SSC1 and SSC2).
The technician assigns the output switching signal (OSS1) to trigger on a user-defined condition – in this instance, when both SSC1 and SSC2 are high. The use of a pre-defined delay before triggering the output also prevents false positives from occurring in the event of a momentary change in either of the internal signals.
Every aspect of configuration is driven by intuitive selection on the PocketCodr app, and on completion, the sensor is just reconnected to the machine’s control system.
The sensor’s IO-Link connectivity is also used as an easy interface to the PLC control system of some of the presses. Once configured, each new sensor’s settings are automatically stored on the local IO-Link Master. This then provides plug-and-play replacement of sensors should the need arise, without any loss of functionality and any need for recalibration.
