Functional second-source: E2E-X14C218-R 5M
The E2E-X12C218-R 5M: The E2E-X14C218-R 5M is the closest alternative. Both are M18, shielded, NPN NC, with a 5-meter bend-resistant robot cable. The only difference is sensing distance: 12 mm on this part versus 14 mm on the X14C218 — the X14 uses a 4x sensing factor vs. 3x here. Same nickel-plated brass housing, same IP69K, same 10–30 VDC supply. If the application has clearance for the extra 2 mm of detection range, the X14C218 drops directly into the same bore and wiring. For precise 12 mm targeting, stay with this code.
Threaded M18 body with a 33 mm threaded length and 55.3 mm overall. Shielded construction means no derating for flush mounting in metal. Three-wire DC: brown to 10–30 VDC, blue to ground, black is the NC load (NPN). The 5-meter PVC robot cable is bend-resistant for flexing applications. Supply voltage range 10 to 30 VDC.
