Checker 232 inspects small features over a wide area
Cognex Corporation, a leading supplier of machine vision systems and vision sensors has added the Checker® 232 model (Figure 3) to its award-winning Checker vision sensor product line. Designed to inspect small features over a wide area, Checker 232 provides reliable inspection results on the fastest production lines, detecting and inspecting up to 1,500 parts/min.

Checker 232 is ideal for applications where small features are being inspected on large parts, such as the inspection of clips and springs on large automotive assemblies. Checker 232 is also ideal when a much longer working distance is needed and the vision sensor must be mounted far from the area to be inspected.
“Customers value the simplicity and power of Checker vision sensors because they offer a very cost-effective option for inspections where traditional sensors are not reliable and a full-blown vision system is too expensive,” said Pascal Dorster, Senior Director, Vision Sensors Business Unit. “The Checker 232 extends the versatility of the Checker product line so customers can solve a broader range of inspection applications more effectively.”
Unlike traditional sensors, there’s no limit to the number of part features that a single Checker can inspect. Checker uses patent-pending multi-image analysis to determine if a part is present without an external trigger, greatly simplifying installation. This unique capability also enables Checker to track parts in varying positions along the production line, overcoming imprecise part positioning and delivering consistent, precisely timed pass/fail results. No other sensor, vision sensor, or vision system can do this.
The Checker 200 series are simple to set up, small enough to fit almost anywhere, and offer IP67 protection. Checker 232 joins three existing 200 series models: The Checker 200 for part detection, the Checker 201 for part detection and inspection, the Checker 202, with ladder logic when more complex pass/fail decisions are needed.
The Checker 232 combines the features of the 202 with the ability to inspect smaller features over a larger area. Checker 201, 202 and 232 are available with the Cognex SensorView™ 350, a compact, industrial, panel-mount display. The Checker 232 is currently available.
