Capacitive sensors respond to a change in capacitance caused by a nearby target. Detection depends on the material, target size, gap and sensitivity adjustment; verify the actual application as well as the catalog reference target.

|---|---|
| TCB and TCC Large-Face Capacitive Proximity Sensors TCB and TCC are large-face capacitive sensor families with 80 and 120 mm nominal catalog ratings. Compare the reference target, working distance and model-specific power supply. | 23 |
| GC12 GC18 GC30 Cylindrical Capacitive Sensors GC12, GC18 and GC30 provide switched capacitive detection in cylindrical housings. Select the flush or non-flush column, full output code and actual target material. | 24–25 |
The catalog describes sensitivity adjustment by potentiometer, red LED status indication, reverse-polarity/surge/short-circuit protection, an operating range of −25 to +70 °C and IP67 for the tabulated models. Check the exact housing material and output in the selected family table; these details are not universal across every capacitive model.
No. Material and geometry affect capacitive detection. Check the intended target, sensitivity and operating gap with the selected model.
The catalog labels these rows DC two-wire. Confirm the complete circuit and supply; do not infer AC from the letter A.
