The IFRH 12P3501/L: 10143039 offers a nominal sensing distance of 2 mm and supports a PNP break function (Normally Closed) output, making it suitable for safety loops, monitoring systems, and reverse logic applications. Its flush-mounting design ensures smooth integration into space-restricted environments without protruding hardware. With a switching frequency of 2 kHz, it enables rapid detection cycles, which are essential in high-speed automation tasks such as bottling lines, tool positioning, and rotary indexing tables.
The sensor operates across a broad voltage range of 6–30 VDC, with a low current draw of 12 mA (no load), supporting energy-efficient machine design. It can handle a load of up to 200 mA, with a voltage drop of less than 2 VDC, ensuring reliable signal transmission to downstream control units. The sensor body is built from brass nickel-plated material with a PBT sensing face, providing excellent mechanical and thermal resistance. Its 12 mm threaded cylindrical housing ensures fast installation in standard industrial brackets.
With an impressive temperature range of -25°C to +180°C and IP67 ingress protection, the Baumer IFRH 12P3501/L is engineered for durability in challenging environments. The integrated 2-meter cable simplifies wiring for fixed or panel-mount installations. Trusted for its stable performance and industrial-grade construction, this sensor is a dependable component for OEMs and factory automation teams. The Baumer IFRH 12P3501/L is specifically designed for tasks where default-closed logic is required for system safety or logic inversion. In material handling systems, it acts as a critical sensing component to confirm object presence, part alignment, or gate positioning. The NC output ensures that any wiring issue or device failure results in an open circuit—making it safer for use in emergency stop chains and fail-safe circuits.
In automated press machines and robotic pick-and-place systems, the sensor’s flush mounting ensures it remains protected while still delivering accurate proximity sensing for fast-moving metal parts. The high switching frequency and fast response time ensure no object goes undetected during high-speed operation.
For industries that involve high temperatures—such as automotive, metal fabrication, or glass processing—the Baumer IFRH 12P3501/L delivers uninterrupted service even in hot zones, thanks to its wide thermal range. Its rugged IP67 housing also makes it suitable for use in dusty, humid, or splash-prone environments like paint booths and food processing zones. This sensor is a go-to solution for plant engineers seeking both reliability and fail-safe control.
