Balluff BES M12MI-PSC40B-S04G | M12 Inductive Prox 4mm PNP NO 3-Wire, Shielded, M12 Plug
Balluff BES M12MI-PSC40B-S04G inductive proximity sensor — M12 × 1 shielded, 4 mm flush sensing range, PNP NO 3-wire, 10–30 V DC, M12 × 1 4-pin plug. Stainless steel housing, IP67.

Product Overview

The Balluff BES M12MI-PSC40B-S04G​ (Order Code: BES02L3 / BES00C8 depending on regional catalog) is a standard M12 inductive proximity switch​ for non-contact detection of ferrous metal targets. It features a shielded (flush-mountable) M12 × 1 mm brass/nickel-plated or stainless steel barrel, 4 mm nominal sensing range when flush-mounted, and a PNP Normally Open (NO) 3-wire DC output. Connection is via an integral or matching M12 × 1, 4-pin A-coded male connector (S04G = M12 plug, 4-pin, straight)​ — cable version would be "-C-...". Operating voltage is 10–30 V DC​ with short-circuit, reverse-polarity, and overload protection. LED indicator shows switching status. Suitable for conveyor, packaging, and general machine automation.

Key Features

  • Flush-Mountable (Shielded):​ Can be installed flush with metal surfaces without reducing sensing range due to neighboring ferrous material — simplifies mechanical design.
  • High Switching Frequency (2 kHz):​ Detects fast-moving parts on high-speed conveyors or rotary indexing tables.
  • PNP NO 3-Wire Standard:​ Industry-default for European and Asian machinery — directly interfaces with most PLC digital inputs.
  • M12 A-Coded 4-Pin Plug (S04G):​ Quick-disconnect — no field soldering; use standard M12 4-pin female cordset (e.g. Balluff BCC...).
  • Rugged Metal Barrel:​ Nickel-plated brass withstands mechanical impact and coolant/oil splashes in shop-floor environments.

Typical Applications

  • Conveyor Part Detection:​ Verify presence/absence of pallets, cans, bottles, or metal stamped parts on transport lines.
  • Machine Tool Position Check:​ Confirm fixture clamped, guard closed, or slide at home position before cycle start.
  • Automation Indexing:​ Count metallic tabs or detect cylinder end-position via embedded metal target.
  • Packaging Machinery:​ High-speed product-in-place verification prior to sealing/labeling.
Code Decode: BES = Balluff Inductive Sensor | M12MI = M12 threaded, shielded (flush), metal housing | PSC40B = PNP NO, 4 mm range, 10–30 V DC, short-circuit protected | S04G = Connector M12 × 1, 4-pin A-coded, straight male plug (pigtail/cable would be e.g. -C- with length). Mating cordset example: Balluff BCC M323-0000-1A-004-XF2434-030 (M12 4-pin F to open ends, 3 m). For NPN version see BES M12MI-NSC40B-S04G.
