Balluff BES 516-356-G-SA21-S4-C Proximity Sensor

Balluff BES 516-356-G-SA21-S4-C Proximity Sensor is a cylindrical inductive proximity switch from Balluff’s BES01H6 family. It delivers a 4 mm sensing range and runs on a 10–30 V DC supply, with a PNP normally open (NO) output through a 4‑pin M12x1 connector. The sensor's stainless‑steel body measures Ø12 x 70 mm and uses a non‑flush installation, rated IP68 for dust and water ingress protection and a operating temperature range of −40 to 85 °C. The sensing face is made of PBT, and the device typically draws around 200 mA during operation. Common applications include metal‑presence detection on conveyors, end‑of‑travel sensing, and general position sensing in harsh manufacturing environments, where integration with standard industrial controllers is straightforward thanks to its DC power and NO output. This variant sits within Balluff’s BES01H6 portfolio and is compatible with Balluff automation ecosystems and industry‑standard control architectures.
