2. Precise End-Position Monitoring for Machine Tools

The NBN40-U1-A2-T is suitable for monitoring the end positions of moving metal components in machine tools or robotic arms. Its robust PBT housing and wide operating temperature range (-25 to 100 °C) allow it to withstand the demanding conditions of machining environments, while the high switching frequency (180 Hz) provides fast response for dynamic applications. The complementary output (NO/NC) offers flexibility in control system integration.

Problem Solved

Provides reliable and fast feedback on the precise position of metallic machine parts, enhancing safety and accuracy in automated manufacturing processes under challenging temperatures.

3. Non-Contact Level Sensing in Metal Hoppers/Chutes

Utilized in material handling for packaging lines, this sensor can detect the presence or absence of metallic materials (e.g., fasteners, small metal parts) in hoppers or chutes. Its non-flush design and 40mm range allow for installation outside the material flow, minimizing wear. The IP68 protection safeguards against dust and incidental liquid splashes common in packaging operations. The rotatable sensor head enables easy alignment.

Problem Solved

Ensures continuous material supply and prevents overfilling or underfilling in automated packaging processes by reliably detecting metallic material levels in a robust, non-contact manner.
