Baumer IFRM 05N35A3/KS35PL Proximity Sensor

The IFRM 05N35A3/KS35PL from Baumer is engineered for accuracy in tight spaces, featuring a flush mount cylindrical threaded body just 5 mm in diameter and 20 mm in length. This inductive sensor offers a nominal sensing distance of 1 mm and a rapid switching frequency of 5 kHz, making it ideal for fast-paced industrial applications. It uses an NPN break function (NC) output and supports loads up to 200 mA, ensuring reliable switching even under dynamic operational loads. Operating on a 6–30 VDC supply and consuming just 12 mA at no load, it ensures energy efficiency. The sensor housing is constructed from stainless steel, and the LCP sensing face offers high chemical resistance, suitable for harsh industrial environments. Its integrated Flylead M8 connector with a 200 mm cable enables quick, flexible installation. With an IP67 rating and an operating temperature range of -25°C to +75°C, this sensor performs reliably in dusty, humid, or oily setups across industries.

The Baumer IFRM 05N35A3/KS35PL is highly suitable for miniature conveyor systems, robotic grippers, and assembly line jigs where space is limited but detection precision is crucial. Its flush mount design prevents sensor damage and allows it to be embedded seamlessly into fixtures or machine walls. In electronics manufacturing, it detects small metallic components with high repeatability. In pharmaceutical automation, it ensures tool and cap presence verification in high-speed filling or sealing machines. The fast response time of 5 kHz makes it ideal for motion-driven applications like pick-and-place arms and rotary indexing tables. With a rugged design and a simple plug-and-play flylead connector, it reduces downtime during maintenance or retrofitting. Engineers prefer this model for its blend of robustness, size, and consistent output — especially in systems requiring silent, contactless detection with no mechanical wear.
