fm has introduced its new robust fail- safe inductive sensors, engineered for the food and beverage industry. These cutting-edge, all-metal sensors establish a new standard for safety and reliability in extreme conditions. ifm is the first and only supplier to offer fail-safe inductive sensors in a durable full-metal design, ensuring maximum safety even in environments with constant moisture or temperatures ranging from -25°C to 100°C. These features make them ideal for critical applications in the food and beverage
sector.ifm Introduces Fail-Safe Inductive Sensors for the Food Industry
The company’s full-metal inductive sensors are perfect for various safety- critical uses. For example, they can be installed on service lids and manways to prevent processes from starting until lids are securely closed, protecting both personnel and machinery. They are also well suitable for valves and valve manifolds, withstanding frequent cleaning cycles and continuous moisture exposure. Additionally, they ensure reliable operation of cold storage high-speed doors, even in low temperatures.
