Festo SIEN Series Proximity Sensor, 2.5mm Detection Range, 200mA Switching Current - SIEN-M8NB-NS-K-L , Numeric Part Number: 150392


This proximity sensor is an inductive type designed for industrial applications. With a compact threaded barrel style and dimensions of 35mm in length, it offers reliable performance across a temperature range of -25°C to +70°C. This sensor operates with an NPN output and is suitable for detecting metallic objects at a distance of 2.5mm, making it highly effective for automation needs.

Features & Benefits


• Detection range of 2.5mm enables precise object identification
• Operates effectively between 10V to 30V DC for versatile usage
• Compact threaded barrel design facilitates easy installation in restricted spaces
• IP65 and IP67 ratings provide protection against dust and water ingress
• Short-circuit overload protection enhances operational safety

Applications


• Utilised in factory automation for position detection
• Implemented in conveyor systems for metal detection
• Suitable for machine tools where precise object positioning is critical
• Effective in robotic systems for end-of-arm tooling

What are the specific environmental conditions under which it can operate?


It can function effectively in ambient temperatures ranging from -25°C to +70°C, allowing for versatile use in various industrial settings.

How does the output function affect its application in automation?


The NPN output configuration enables seamless interfacing with control systems, making it ideal for real-time integration into automation processes.

What materials are compatible with the sensing capability?


The sensor can detect materials with specific reduction factors

for example, it performs best with steel (1.0) and less effectively with aluminium (0.25), allowing for tailored applications based on material type.

How does the housing material contribute to the sensor's durability?


Constructed from PBT and high-alloy stainless steel, the housing offers enhanced resistance to environmental stress and ensures long-lasting performance.
