Versatile integration

inSpect Bent Pin seamlessly integrates with any component and assesses a diverse range of pins to meet any need. Accommodating connectors up to 60mm in width, our technology ensures comprehensive assessment of the X, Y, and Z coordinates of pins within these connectors. This guarantees that all measurements align with the required tolerances, regardless of the connector’s dimensions or type.


Critical pin height verification for reliable connections

It is crucial to verify the orientation and height of connector pins before insertion into a board or another connection point. While bent or missing pins are relatively straightforward to identify, subtle discrepancies in pin height can cause significant issues. A pin that is too short may lead to a disconnected circuit, whereas an overly tall pin might prevent other pins from connecting properly. Minor variations in pin height can cause voltage drops or intermittent faults that are challenging to diagnose once the assembly is integrated into the device, making early detection critical.

inSpect Bent Pin, equipped with a sensor mounted on a linear servo motor, traverses the X-axis to inspect each connector. All measurements are calibrated against a predefined connector reference plane, ensuring precise and consistent positioning assessments. This solution is tailored for industries requiring impeccable precision in connector assembly and quality control.

Achieving micron-level precision in connector pin inspection

inSpect employs micron-level accuracy to examine connector pins. The technology is designed for precise assessment of the X, Y, and Z coordinates of pins within various connector types, ensuring that all measurements fall within required tolerances.

The system provides a high-resolution image that facilitates precise measurements of pin heights and the detection of defects.
Capable of addressing various challenges, including differences in connector depths, colours, and sizes, as well as variations in housing designs, inSpect also mitigates reflections from pins and accommodates the inherent instability of differing pin dimensions and materials.

Essential for maintaining maximum stability, the system undergoes strict Measurement System Analysis (MSA).

Advanced imaging technology for industrial inspection

The visual inspection equipment features a powerful camera paired with a telecentric lens and advanced four-sided projection lighting. With telecentric optics and high dynamic range (HDR) imaging, our laser displacement sensors effectively manage contrast to eliminate noise from bright and reflective features, ensuring precise adherence to manufacturing tolerances for connector pins and elevating overall product quality.
Each captured image is composed from 16 individual images, utilizing unique colour, angle, and projection patterns to maximize accuracy. Throughout the inspection process, connector images undergo compression and are seamlessly stored on our servers, tagged with DMC codes for effortless traceability and retrieval.
