Pepperl+Fuchs NJ0,8-4,5-N Inductive sensor / 70133211

Core Features

• ✓  Ultra-compact design: With a diameter of only 4.5mm, it is suitable for installation in extremely small spaces.
• ✓  NAMUR output: Intrinsically safe, requires a certified isolation barrier or switching amplifier.
• ✓  Flush mounting: Supports flush mounting, preventing interference with surrounding metal.
• ✓  High protection rating: IP67 protection rating, providing strong waterproof and dustproof capabilities.
• ✓  Safety certification: Complies with SIL 2 (IEC 61508) standards, suitable for systems with high safety requirements.

Q: Can this product be used independently?

A: No, this product must be used with an amplifier/safety barrier: NJ0,8-4,5-N itself does not have relay or transistor outputs and cannot directly drive PLC input modules (unless the PLC supports NAMUR input). It must be connected to a NAMUR amplifier or an isolated safety barrier (such as P+F's KFD2-STC4-EX1 or similar models) to be converted into a standard switching signal.

Q: What precautions should be taken when installing this product?

A: Pay attention to the installation torque. Since it is an M4 thread, be careful with the torque during installation to avoid damaging the casing.

Q: In which fields is this product mainly used?

A: High-speed counting: Due to its small size, it can be used to detect tiny parts; Safety-critical applications: When used with safety barriers in flammable and explosive environments (such as chemical, petroleum, and pharmaceutical industries); Space-constrained applications: The ultra-small diameter of M4 allows it to be installed in extremely narrow spaces.
