Description
Pepperl+Fuchs NJ15-30GK-SN-5M 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 with safety function output type. With support for flush mounting, it adapts easily to tight or embedded installations. Constructed with a durable Crastin (PBT) housing, it offers mechanical resilience in harsh environments. With an ingress protection rating of IP68, the sensor is well-protected against dust and water. Suitable for extreme working conditions, it performs reliably within ambient temperatures of -40 ... 100 °C (-40 ... 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. • Usable up to SIL 3 acc. to IEC 61508 • Degree of protection IP68 • ATEX-/IECEx-approvals for zone 0/1/20/21 (Ex i) • ATEX-/IECEx-approvals for zone 2/22 (Ex ec/tc) • 5 meter connection cable • 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
