Balluff BCSM30B4M2-PPM20C-S04G Capacitive Sensor

Balluff BCS004T (BCS M30B4M2-PPM20C-S04G) is a cylindrical, flush-mount capacitive sensor with an M30 thread, designed for reliable object detection in industrial automation. The housing is 1.4301 stainless steel, with a PBT sensing surface, and measures Ø30 x 87 mm; installation is suited for flush mounting. It operates from 10 to 35 V DC and draws up to 300 mA, and it provides a programmable PNP output (NO/NC) via a 4‑pin M12 connector; sensing range is 1–20 mm (Sn 20 mm). The device is IP66 rated and rated for temperatures from -30 to 70 °C, with CE, UKCA and cULus approvals. This Balluff sensor is well suited for detecting dielectric objects in constrained spaces on conveyors, packaging lines, or machinery where non-contact presence or level sensing behind protective housings is required.
