15 mm sensing range, 35 mA output — what it means on the line
The XS7-C40AS101 is a Telemecanique-branded inductive proximity switch with a 15 mm sensing range and a 35 mA output — a standard barrel-style sensor for detecting ferrous targets in automated machinery. The 15 mm range means it can detect a mild-steel target at that distance; for non-ferrous metals like stainless or aluminum, the effective range drops by a correction factor (typically 0.7× for stainless, so budget ~10.5 mm). At 35 mA output, this sensor can drive a PLC input directly or switch a small relay coil — the current draw is well within the capacity of most 24 VDC control supplies.
The cable exit and connector orientation (if any) are not detailed in the spec, but the form factor is consistent with Telemecanique's XS7 series, which uses a 4-wire DC output.
