Not a drop-in for the heat-resistance E2C-X1R5AH
The E2E-X3D1S-P1: The E2E-X3D1S-: The E2C-X1R5AH is a heat-resistance model with pre-wired cable (3 m), a 1.5 mm sensing distance, and a wider temperature range (-10 to 200 °C ambient). The E2E-X3D1S- uses an M12 connector, senses at 3 mm, and does not share that extended thermal rating. The mounting dimension also differs: the E2C head is M8, while the E2E-X3D1S- uses a different body size (not listed, but the connector and sensing distance confirm a non-matching footprint). This is not a form-fit-function alternate.
