Baumer IFRD 08N37T1/S35 Proximity Sensor

The IFRD 08N37T1/S35 from Baumer is a high-reliability quasi-flush inductive switch with a 2 mm nominal sensing distance and rugged stainless steel construction. It supports a NPN break function (NC) output circuit, offering fail-safe behavior for critical stop or reverse logic operations. Operating within a 10 to 30 VDC supply range and consuming just 20 mA, the sensor is designed to function efficiently while maintaining signal stability. Its switching frequency of 150 Hz enables fast response in dynamic control systems, while a voltage drop below 2 VDC and 100 mA output current capacity ensure consistent performance even in demanding electrical environments.

Designed with a compact 8 mm cylindrical threaded housing and 46 mm length, this sensor integrates seamlessly into tight spaces on production machines or robotic assemblies. The stainless steel 1.4404 (V4A) housing and sensing face offer superior resistance to corrosion, pressure (up to 20 bar static), and mechanical shock. With IP69K protection class, it withstands high-pressure cleaning, steam, oil, and dust—making it suitable for both dry and wet industrial zones. The M8 connector ensures easy and secure installation, contributing to reduced downtime and maintenance.

The Baumer IFRD 08N37T1/S35 is widely adopted in applications where equipment shutdown or safety interlocking is needed when metallic objects are absent or removed. This includes food packaging lines, automated tooling stations, and hydraulic press systems where non-contact detection with normally closed logic enhances system safety.

Engineers prefer this special version sensor when designing for abnormal condition response—where circuit break on detection loss is critical. Its ability to maintain signal integrity even in washdown or high-temperature conditions makes it ideal for industries like pharmaceuticals, dairy processing, and metallurgy. The sensor's compact size and pressure resistance make it suitable for retrofitting into existing enclosures or tight machine spaces.

With its specialized NPN NC output, fast-switching capability, and rugged stainless-steel body, the Baumer IFRD 08N37T1/S35 Inductive Sensor stands out as a reliable, safety-conscious sensing solution in advanced automation environments. Its design supports engineers building future-ready, fail-safe, and maintenance-efficient systems.
