A100 Double Sheet Detection System

Product catalog summary

Overview: The document describes the A100 Double Sheet Detection System, designed to prevent multiple sheets from being fed into processing machines, which can cause damage and production loss. The system uses single probe permanent-magnetic sensors to detect changes in magnetic flux caused by sheet interference.

Specifications:

Ferrous material thickness detection range: 0.04 - 4 mm (0.0015 - 0.16 in).
Control units available for DIN-rail mounting (IP00) and machine frame mounting (IP54).
Operating voltage: 24 VDC with a power consumption of approximately 2.7 W.
Ambient temperature range: 0° - 50°C (32° - 122°F).
Class of protection: IP65 for sensors.

Functionality: The sensors detect magnetic flux changes and convert them into electrical signals, which are processed by the control unit and used as switch signals. The system can monitor the presence or absence of layers and the correct positioning of materials.

Sensor Mounting Recommendations:

Flush mounting is recommended to prevent wear and debris accumulation.
Recessed mounting is possible but should be filled with non-ferrous materials to avoid debris accumulation.
Spring-loaded mounting is beneficial for thick plates to maintain proper sensor positioning.

Installation and Setup:

Sensors can be mounted horizontally or vertically.
Teach-In procedure involves placing a sheet on the sensor, pressing the SETUP and NEW keys, and verifying LED indicators for single and double sheet detection.

Technical Data:

Switching outputs: Opto coupler outputs, output sourcing (PNP).
Temperature drift of switching point: ± 0.02% / °C.
Switching capacity: max. 30 V, max 10 mA.
Minimum dwell time of the sheet on the sensor: 15 ms.

Order Information:

Control units: A100 for DIN-rail mounting, A100-S for machine frame mounting.
Sensors: Various models available with fixed cables or connecting sockets.
Cables: Standard length is 2m, extendable up to 20m upon order.

A100 DOUBLE SHEET Application When feeding sheets automatically, more than one sheet can be inadvertently fed into the processing machine. This can result in damage of the machine and tools, expensive repairs and production loss. The single probe Double Sheet Detector A100 has been designed to prevent such events. The permanent magnetic sensors detect electronically magnetic flux changes caused by sheet interference. The magnetic flux changes are transformed into electrical signals by the sensors. These electrical signals are processed by the control unit and sent to the machine controls for...
