Summary: During manufacture of mechanical assemblies for automotive production, an operator uses a manually operated machine to weld metal parts together. After welding, the operator drops the assembly in a transport bin ready for dispatch. As each assembly is placed in the bin, an infrared light curtain detects its presence and confirms that the welding cycle has been completed correctly. Customer Values: Reliable, repeatable detection of fast-moving parts Testing is completed in-cycle witho …

Summary: A hooklift truck utilizes a hydraulic system for loading and unloading a demountable container. Once the container is correctly positioned on the vehicle’s load bed, interlocks engage with its base, securing it in position. Rugged sensor systems detect full engagement of the interlocks, ensuring the truck is safely loaded prior to driving away; sensors must be mechanically robust and withstand harsh outdoors conditions. Customer Values: Elimination of human error prevents truck …

Summary: Modern road bridges typically utilize beam construction; mobile cranes lift prefabricated bridge sections onto pairs of support columns. Multiple heavy-duty hydraulic cylinders support the ends of each section, allowing accurate height adjustment prior to final positioning. Engineers require rugged sensor systems that detect the position of each cylinder accurately; sensors should be mechanically robust and must withstand harsh outdoors conditions. Customer Values: Simple sensor syst …

Swiss safety-systems specialist Contrinex launches a new high-speed Safety Relay suitable for use with its Safetinex Type 2 and Type 4 light curtains. With a faster re-sponse time of just 10ms, the new Safety Relay allows engineers to specify shorter overall safety distances when designing safety systems in accordance with ANSI B11.19 or EN ISO 13855 standards. The new Safety Relay, designed for the protection of people and machines, is a Performance Level (PL) e, category 4 device according to …

The Contrinex High Temperature range includes sensors in sizes from M8 to M50. Sensors that have an internal amplifier resist temperatures of +180°C, while those with an external amplifier withstand temperatures up to + 230°C. Particular attention has been paid to long-term stability under the most demanding conditions. With operating distances from 2 to 25 mm, these sensors are suitable not only for high precision applications, but also applications with greater tolerances and distance …
