The Baumer IFRM 08N3701/KS35L is engineered with a flush mounting type and a precise 2 mm sensing distance, ideal for short-range metal detection. With its NPN break function (NC) output, itβs particularly useful in safety circuits or systems where an open signal indicates object presence. It operates efficiently on a wide voltage range of 6β36 VDC and consumes only 12 mA in a no-load state, reducing power demand on the system.
This sensor stands out with its switching frequency of 5 kHz, allowing it to respond quickly to fast-moving targets in automated production lines. Built with a robust stainless steel cylindrical threaded housing (8 mm diameter, 30 mm length), the sensor ensures long-lasting performance even under mechanical stress or vibration. The PBT sensing face and IP67 protection class provide reliable operation in dusty, wet, or oily environments. A clearly visible red LED output indicator gives instant feedback during installation and operation, reducing troubleshooting time. The integrated M8 flylead connector supports flexible wiring while maintaining signal integrity. With these attributes, the Baumer 2 mm NPN Break Function Switch is trusted by OEMs and system integrators across demanding sectors.
Applications of Baumer IFRM 08N3701/KS35L
The IFRM 08N3701/KS35L is ideal for use in automated inspection systems where a missing or misaligned metal part must trigger a fault condition. Its break function logic makes it a perfect fit for fail-safe applications, such as confirming that safety covers or guards remain closed during machine operation. In conveyor-based systems, it helps detect part presence or misfeeds without physical contact, increasing system life and reducing maintenance.
In automated packaging and bottling lines, the sensor ensures accurate position verification of metallic components like caps, blades, or frames. For Indian engineering students and junior maintenance engineers, this sensor serves as a practical example of digital input integration using non-contact switches. Senior engineers prefer it for its rugged build, fast switching, and ease of replacement in field retrofits. With Baumerβs global reputation and proven performance, this sensor offers long-term value for any industrial automation project.
