Wenglor Unveils High-Precision Miniature Fork and Dual-Variant Label Sensors
Space-constrained automated environments—such as shuttle systems, autonomous guided vehicles, and robotic end-effectors—frequently present engineering obstacles for standard optical detection hardware. Addressing these spatial limits while targeting low-contrast packaging materials, Wenglor Sensoric Group has expanded its industrial automation portfolio with two specialized product lines: ultra-compact miniature fork light barriers and dual-technology label sensors.
The newly introduced miniature fork light barriers feature a condensed physical footprint engineered to integrate directly into tight mounting rails without increasing end-effector mass. Available in fork widths of 10 mm, 20 mm, and 30 mm, these devices deliver reliable detection for micro-components as small as 0.7 mm. To streamline commissioning and eliminate manual device tuning, the series supports IO-Link 1.1 protocol, enabling remote switching threshold configuration directly from a programmable logic controller. Ruggedized with IP67 and IP68 enclosure ratings, the units operate reliably under washdown conditions and high-moisture processing environments without requiring auxiliary protective housings.
Alongside the micro-fork lineup, Wenglor has introduced photoelectronic and ultrasonic label detection units optimized for high-speed web handling equipment. The photoelectronic model utilizes infrared emitter technology to deliver a repeatability specification of ±0.05 mm, ensuring exact edge registration for high-speed paper label applications. Conversely, the ultrasonic variant measures acoustic attenuation differentials between the label stock and backing material. Operating with a rapid response speed of 0.25 ms, this sound-based method overcomes traditional optical limitations, accurately identifying transparent, metallic, high-gloss, and minimal-contrast labels regardless of color or surface reflectivity.
By combining rigid U-shaped alignment structures with modern smart sensor diagnostics, Wenglor's latest release addresses longstanding integration hurdles in automated packaging lines. The incorporation of IO-Link master data storage further simplifies field maintenance, allowing seamless parameter restoration during hardware replacements and minimizing operational downtime across complex conveyor systems.
