The Balluff BES 516-370-G-E5-Y-S4 is a shielded inductive proximity sensor with a 4 mm sensing distance and a 10–30 V DC supply. It provides a 3‑wire, PNP normally closed output via an M12x1 4‑pin S4 connector, with a rated operating voltage of 24 V DC and a maximum load current of about 130 mA. The sensor’s body is Ø12 mm by 50 mm, featuring a nickel‑plated brass housing and a PA12 sensing face, offering Sn = 4 mm with repeatability around 5% and hysteresis near 15%. Operating ambient temperature ranges from -25 to +70 C, it carries IP67 protection and includes polarity‑reversal and short‑circuit protection for reliable performance in industrial environments.
