SLM-5M12, 12mm Lens for Mono BCR Cameras

The SLM-5M12 is a fixed 12mm focal length C-mount lens built for Wisenet BCR (barcode reading) camera systems such as the TNS-7000M. It's engineered to work with 3M~5M resolution cameras and is the part that determines whether a barcode reading station on a conveyor line actually captures a clean, readable image or not. The camera body gets most of the attention, but pairing it with the wrong lens throws off both the read distance and the field of view — and the system starts missing labels or delivering blurry frames.

• 12mm focal length: Matches the mounting height typically used above conveyor belts, keeping the barcode or shipping label properly framed as packages pass underneath.
• C-mount connection: Fits directly onto standard C-mount BCR cameras, including the TNS-7000M, with no adapter required.
• 3M~5M resolution support: When paired with a high-resolution sensor, barcode bars and small print labels stay legible.
• F6 maximum aperture: Maintains usable sharpness even in warehouse aisles with uneven or mixed lighting conditions.
• 21.7°~31.2° horizontal field of view: Helps installers plan camera-to-conveyor mounting distance without the barcode falling outside the frame.
• -20°C to +60°C operating range: Runs reliably in unheated or uncooled warehouse corridors regardless of season.

This lens fits e-commerce fulfillment centers, parcel sorting hubs, end-of-line packaging stations, and automated label/plate reading setups. In high-speed conveyor operations where each box needs to be read on the first pass, getting the camera-lens pairing right has a direct impact on read success rate.
