Balluff BCS M12T4D2-PSM40C-S04G | M12 Capacitive Sensor, 4mm Range, PNP NO, M8
Balluff BCS M12T4D2-PSM40C-S04G capacitive proximity sensor. 4mm flush range, PNP NO, M12x1 thread, M8 4-pin, 10-30V DC, IP67, detects solids & liquids through container walls.

Product Overview

The Balluff BCS M12T4D2-PSM40C-S04G​ (Order No. BCS001W) is a capacitive proximity sensor​ in an M12 cylindrical housing. It detects solids and liquids—even through non-metallic container walls (glass, plastic, ceramic)—making it ideal for level detection in tanks, hoppers, and packaging machines. This model features a 4 mm flush-mountable sensing range, PNP Normally Open (NO) output, and a 4-pin M8 connector.

Key Features

  • Detects Through Walls:​ Can sense water, granules, or powders through glass/plastic vessel walls up to several mm thick (range depends on wall material and dielectric).
  • Flush Mountable:​ 4 mm range when installed flush in metal—no reduction factor loss from adjacent metal.
  • Sensitivity Trim:​ Integrated potentiometer lets you tune the switching point to ignore the container wall itself.
  • Rugged M12 Metal Housing:​ Nickel-plated brass body withstands mechanical stress better than plastic alternatives.

Applications

  • Non-Metallic Tank Level:​ Point-level detection of liquids (water, oil, chemicals) in plastic or glass tanks.
  • Hopper / Silo Monitoring:​ Detect presence of granulate, powder, or pellets through the bin wall.
  • Packaging QA:​ Verify product presence inside blister packs, bottles, or cartons on filling lines.
  • Machine Build:​ Web break / material presence detection for paper, film, or non-woven through a guide roller.
Note: For NPN output or cable version, see other BCS M12 variants (e.g., BCS M12T4D2-PSC40C-S04G for NPN). Sensitivity should be adjusted via the onboard pot when sensing through a container wall to avoid false triggering on the wall itself.
