Baumer IFRH 18P1501/L Proximity Sensor

The IFRH 18P1501/L: 10143354 delivers reliable object detection with a nominal sensing distance of 5 mm and a flush-mountable cylindrical housing design that enables easy integration into machines with limited space. With a robust stainless steel housing and a PBT sensing face, this sensor is designed to perform reliably in high-vibration and harsh industrial environments. It features a PNP make function (Normally Open) output that can handle up to 200 mA of load, ensuring consistent signal transmission to control systems and PLCs.

The sensor operates within a voltage range of 6–30 VDC and consumes a maximum of 12 mA (no load), making it energy-efficient for 24/7 operations. It supports a switching frequency of 1 kHz, suitable for detecting fast-moving components in packaging, bottling, or automated storage systems. With a diameter of 18 mm and a housing length of 71 mm, it provides flexibility for varied mounting depths. The unit includes a durable 2-meter cable for easy wiring and supports an operating temperature range of -25°C to +180°C, making it suitable for environments exposed to heat, oil, and moisture.

Rated with IP67 protection, the Baumer IFRH 18P1501/L is trusted for its ruggedness and longevity, especially in applications where dust, water, and machine oil are present. The Baumer IFRH 18P1501/L is designed to deliver accurate detection in a variety of industrial use cases, especially where longer sensing distances and high durability are required. Its 5 mm sensing range makes it suitable for detecting metallic parts on conveyors, palletizing systems, and moving tooling platforms, even when the sensor is mounted behind protective covers or recessed.

In industries like automotive and steel fabrication, where machinery is exposed to heat, vibration, and airborne debris, this sensor maintains consistent output thanks to its IP67 protection rating and high thermal tolerance. Maintenance engineers prefer this sensor for monitoring machine parts such as shafts, gear positions, and clamps, where wear-and-tear-resistant sensors are essential.

With its flush mounting and long housing format, the IFRH 18P1501/L is often used in packaging machinery, automated warehouses, and bottling lines where compact design meets performance. Its high switching frequency also makes it compatible with pick-and-place systems that require quick, repeatable detection. Whether you're setting up a new production cell or upgrading old systems, this sensor brings both precision and peace of mind.
