Datasensing PFM1/BN-4H Sensors

The Datasensing PFM1/BN-4H Sensors are designed with a robust AISI 316L stainless steel housing, ensuring durability and resistance to harsh environments. Equipped with an LED status indicator, these sensors offer reliable performance with IP67, IP68, and IP69K protection degrees, making them suitable for a wide range of industrial applications. ATEX models, category 3, are available upon request for environments requiring explosion protection. These sensors feature a nominal sensing distance of 8mm and an operating distance of 0 to 6.48mm, with a standard target size of 24x24mm FE360. They are designed to handle various materials with correction factors for copper (0.33), aluminium (0.40), brass (0.45), and stainless steel (0.75). The thermal drift of Sr is less than 10%, and they maintain a repeat accuracy of less than 5% at 24V and 23°C ±5°C. The hysteresis ranges from 1 to 20%. The PFM1/BN-4H Sensors function as proximity sensors with an NPN output type and offer both NO and NC output functions. They support a switching frequency of 2kHz and operate within a voltage range of 10 to 30Vdc. The sensors have a no-load supply current of ? 15mA, a load current of ? 200mA, and a leakage current of ? 15?A. The output voltage drop is ? 2V at 200mA, with a maximum ripple content of ? 10%. Additional features include short-circuit protection, reverse polarity protection, impulsive overvoltage protection, and protection against inductive loads. The sensors are unshielded and have dimensions of M12 x 1 with a length of 64.6mm. They weigh 30g and have an active head made of PPS. The tightening torque is 25Nm, and they operate within a temperature range of -40°C to +80°C, with short exposure capability up to 100°C during cleaning processes. The sensors are CE, cULus, ECOLAB, and DIVERSEY approved, ensuring compliance with international standards. They are EMC compatible with IEC 60947-5-2 and withstand shocks and vibrations as per IEC 60068-2-6 and IEC 60068-2-27 standards. Supplied accessories include two M12x1 nuts, and the sensors are equipped with mechanical protection rated at IP67.
