The 872C-D5NE18-D4 inductive proximity sensor by Allen Bradley is designed for efficient operational use in industrial settings. This component can switch at a frequency of up to 1000 Hz and has a sensing range of 5 mm (0.20 in), making it suitable for a variety of applications requiring precise detection. Its barrel measures 18 mm (0.71 in) in diameter and is constructed from nickel-plated brass, complemented by a durable plastic face.
This sensor's housing meets multiple enclosure ratings including NEMA types 1, 2, 3, 4, 6P, 12, and 13, along with an IP67 rating according to IEC 529 standards, ensuring robust protection against environmental factors. It features a quick-disconnect connection style with a 4-pin micro M12 configuration, promoting ease of installation and maintenance.
Additional characteristics include a vibration tolerance at 55 Hz with a 1 mm amplitude across three planes, and the ability to withstand a shock rating of 30 g for 11 milliseconds. An easily visible red status indicator provides a clear signal when the output is energized, ensuring operational visibility from all angles. For effective signal processing, the sensor demonstrates a typical hysteresis of 10% and a manageable voltage drop, which is ≤6.5V at a current of 200 mA and ≤6V at 100 mA.
