Third-generation vision sensor

Cognex Corporation has added the Checker 3G Series to its Checker vision sensor product line. With simple setup, integrated part detection, lighting, I/O and job change all in a rugged IP67 housing, Checker 3G is designed to offer easy and reliable verification of all products or parts on the line.

With Checker 3G, the user chooses whether to configure the sensor as a presence sensor or measurement sensor. Presence sensors verify that features are present. Measurement sensors verify that features are the correct height, width and/or diameter. In either mode, there is no limit to the number of part features that a single Checker can “check”. Checker is also able to detect and track over 6,000ppm in varying positions along the production line, overcoming imprecise part positioning and delivering consistent, precisely timed pass/fall results.

The new Cognex offering does not require a PC for setup. Instead, the SensorView Teach Pendant, with its “one-click” setup technology, allows the user to set up jobs right on the line and has them running in a matter of minutes.

Sensors monitor pistons in pneumatic cylinders

For automated equipment where piston position must be closely monitored, Baumer Inc. has introduced a new line of magnetic T- and C-slot cylinder sensors that provide discrete output regarding the end-of-stroke position of pistons in pneumatic cylinders.

Compact and economical, these non-contact sensors offer precise, repeatable switching behavior with defined and tested activation sensitivity.

The sensor’s rugged, IP67-rated plastic housing provides reliable operation in harsh and wet end-use environments. Five different, universally applicable standard C and T-slot sensors are available for use in round cylinders and cylinders with tie-rods. Baumer Magnetic Cylinder Sensors are designed for quick and easy installation. Available in both NPN and PNP outputs, these sensors feature cable or fly-lead connectors and a wide, 3-30 volt OC supply range.
