The ISA3 is a unique sensor that uses air pressure to verify the presence and proximity of a workpiece.  The placement of raw materials can be confirmed before machining or other fabrication operations.  The correct seating of a component into a jig or fixture can generate a switch output to trigger the next assembly sequence.  ISA3's new display quickly and clearly summarizes workpiece status for the operator.  Establish the switch point in 3 easy steps.  Lower air consumptions, zero exhaust noise, easier wiring, and excellent anti-clogging measures round out this 3rd generation gap checking device.  ISA3 is CE and RoHS compliant, with an IP67 enclosure rating.

The ISA3-L is an IO-Link compatible version of SMC's ISA3 digital gap checker.  A gap checker uses air pressure to verify the presence and proximity of a workpiece.  Applications include confirmation of raw material placement before machining or other fabrication operations, or the correct seating of a component into a jig or fixture to trigger the next assembly sequence.  ISA3-L includes features like 2 sensors detect supply and outlet pressure, to help determine whether and where this is a clog.  NPN or PNP switch type is selectable electronically.  The sub-screen has been divided into 2 screens, to display more information or finer resolution.  The lower limit of the setting range can be extended down to zero.  IO-Link communication expands functionality.  Gap size, supply and outlet pressure are available as 16-bit integers. 6 bits and settings monitor 2 switch outputs.  2 additional bits are available for pressure and error diagnosis.  Settings can be stored by the IO-Link master to copy automatically when replacing or deploying multiples.  ISA3-L is CE and RoHS compliant, with an IP67 enclosure rating.
