Description
Pepperl+Fuchs NJ15-30GK-N-20M is engineered to meet the performance needs of modern automation systems. It operates with a normally closed (nc) switching function and delivers signals through a NAMUR output type. With support for non-flush mounting, it adapts easily to tight or embedded installations. Constructed with a durable Stainless steel 1.4305 / AISI 303 housing, it offers mechanical resilience in harsh environments. With an ingress protection rating of IP67, the sensor is well-protected against dust and water. Suitable for extreme working conditions, it performs reliably within ambient temperatures of -25 ... 100 °C (-13 ... 212 °F). This sensor is a robust choice for a wide range of industrial automation, machine monitoring, and positioning tasks.
Key Features
• Designed for flush mounting, allowing installation in compact spaces. • NAMUR output • Integrated reverse polarity protection ensures safe electrical installation. • Built-in short-circuit protection increases sensor durability. • Reliable performance across wide ambient temperature ranges. • Durable stainless steel housing suitable for harsh industrial conditions.Specifications
