TRANSPARENT-OBJECT DETECTION SENSORS Transparent-object sensors with Infra-red light or patented UV technology to give you a ‘Clear’ advantage - Reliable detection and accurate counting of clear bottles and trays and a simplified set-up. CLICK HERE to view this product family on Contrinex’s website, or call us to help guide you through selection, or answer your questions. Below are links to additional information.
Customer Solution Contrinex C23 transparent-object reflex sensors with ultraviolet LED- light sources are ideally suited to this application. These miniature cubic devices, mounted between the reel feeder and the loading station, detect the presence of the transparent material loop as its size varies. Positioning the sensors and reflectors is simple using a range of adjustable mounting brackets, and auto-collimated optics which ensure there are no blind zones. Contrinex transparent-object sensors utilise a patented reflex operating principle with polarised ultraviolet light at 275 nm. At this wavelength, absorption of the polarised UV light by a range of commonly used plastics is maximised. Custom-designed UV reflectors, using high-tech plastic materials with excellent reflective properties in the ultraviolet range, are available in a range of sizes and geometries which simplify installation. An industry-standard PNP normally open output ensures optimum flexibility. Additionally, IO-Link, a standardized point-to-point serial connection protocol for sensors and actuators, is enabled on PNP versions at no additional cost. An additional option is to have a second output to provide the stability alarm in the event of reduced sensitivity, flagging the need for preventative maintenance before any performance degradation occurs. The robust sensors which are only 20mm x 30mm x 10mm feature Ecolab-certified plastic housings, are corrosion-resistant and impervious to water ingress and has the additional benefit of offering a range of low-cost stainless-steel mounting and protection bracketry.
APPLICATION - THERMOFORMING TRAYS
APPLICATION - CLEAR PACKAGING
Typically, blister-packaging lines for surgical products operate in sterile conditions; minimal manual intervention is permitted, as contamination may enter the environment. If defective bases are identified and rejected after forming, the flow of tray bases to the loading station is not continuous. In this event, a sensor system must inhibit the loading cycle until a base is in position. Sensors must detect the presence of transparent tray bases swiftly and reliably, enabling the loading cycle to proceed with minimal delay as soon as a tray is present at the loading station. Standard photoelectric sensors, which use visible red-light sources, proved unreliable as they are unable to differentiate reliably between ‘tray present’ and ‘tray not present’ conditions. An alternative sensor is required which will detect the presence of a transparent plastic target under normal operating conditions. Customer Solution Transparent-object sensors with ultraviolet LED-light sources from the Contrinex C23 product series are ideally suited to this application. These miniature cubic devices, mounted above product conveyors, detect the presence of transparent tray bases as they arrive at the loading station. Positioning sensors is simple thanks to a range of adjustable mounting brackets, and auto-collimated optics ensure there are no blind zones.

The robust sensors which are only 20mm x 30mm x 10mm feature Ecolab-certified plastic housings. A sensing range up to 1200 mm, adjustable via a teach button or via IO-Link, accommodates a wide range of machine geometries. Sensitivity parameters are stored on the sensor’s inbuilt memory and may be retrieved or updated remotely via IO-Link, eliminating the need for manual adjustment.

During the automated packaging of fast-moving products, thermoformed transparent plastic tray bases are common. Contrinex’s small C23 transparent-object sensor with patented UV technology detects the presence of each set of transparent trays after it is formed, initiating a subsequent operation and, optionally, triggering a counting circuit. The Ecolab-certification of these sensors make them suitable for the packaging of food and medical products. CUSTOMER APPLICATION A manufacturer of packaging machines for the medical industry produces automated blister-packaging lines for pharmaceutical and surgical products. Medical blister-packs comprise a recessed, semi- rigid tray base, vacuum-formed in-line from a clear thermoplastic material and sealed with a metal or plastic film after the desired products are loaded.
Thermoforming lines produce transparent plastic blister-trays from continuous reels of material. Contrinex’s transparent-object sensors with patented UV technology are used to detect the presence of the transparent plastic sheet as it is unwound from the reel, ensuring the material is correctly tensioned as it enters the loading station. False detection is avoided, ensuring reliable operation with little or no downtime. CUSTOMER APPLICATION Thermoforming equipment is often used in the production of plastic packaging and is particularly suitable for the continuous production of blister-packs. The process involves the in-line vacuum-forming of clear thermoplastic material into semi-rigid blister-trays which, after insertion of the desired products, are sealed with film. Configurable thermoforming lines are ideal for the high-speed production of such blister-trays from continuous reel-stock material. Coupling a standalone reel-feeder to the loading station of a modular line is quick and simple. In operation, a set of drive rollers draws thermoplastic sheet from the stock reel, creating a continuous loop of material between the feeder and the loading station. Maintaining the size of the loop between defined limits ensures the material is correctly tensioned as it enters the loading station. Sensors detect the presence of the transparent material as the loop size varies, initiating or inhibiting operation of the feeder if the loop becomes too small or too large, respectively. Photoelectric sensors using visible-light sources are unreliable in such an application as they cannot reliably differentiate between ‘material present’ and ‘material not present’ under normal operating conditions.
