Contrinex Inductive Sensors

Inductive Sensor

Robust and highly reliable, Contrinex inductive sensors are the fit-and-forget choice for non-contact detection of metallic targets at distances up to 65mm. Vacuum-encapsulated electronics and metal housings protect against shock, vibration, dust, dirt and moisture, making inductive sensors ideal for highly demanding conditions. An inductive sensor generates a magnetic field that is attenuated by a metal target. As a sensor nears its target, a sensing circuit detects the degree of attenuation and switches the output accordingly.

Contrinex Applications

Filling Machines

Filling machines are widespread in many industries, including solids handling, chemical, food, beverage and pharmaceutical, often operating continuously around the clock. Industrial sensors detect containers, lids, labels and caps, measure fill levels and more, and play a vital role in keeping automated filling equipment running reliably, accurately and with minimal downtime.

Machine Tools

Machine tools impose harsh operating conditions on the sensors needed to control cutting, forming and joining processes that run continuously in many metalworking factories. Common hazards include cutting fluid, cooling sprays, swarf particles and electromagnetic interference, making sensor selection particularly difficult where world-class performance is essential.

Packaging Machines

On the journey from manufacturer to consumer, packaging protects all types of product, including foods, pharmaceuticals, white goods and cosmetics. Although packaging helps bring competitive products to target markets in the best possible condition, costs are often significant, and automation helps minimize the impact.

Special Purpose Machines

Special-purpose machines exploit the versatility and convenience of sensor technology for tasks that range from simple position sensing to complex feature detection and identification, in applications as diverse as electronic assembly and plastic molding. Sensor adaptability is also crucial to the economics of one-off and customized machine production.

Textile Machines

Machinery manufacturers supplying the textile, leather and clothing industries rely on sensors for efficiency, reliability and precision. World-class accuracy is essential for production of technical textiles and for making the carbon or chemical fibers used in modern, innovative products, often in highly automated factories.
