Integrator note: what this sensor brings to a 30 mm non-flush slot
The Omron E2Q6N30MF3HOEE is the E2Q6 series rectangular inductive sensor: 40×40×118 mm, 30 mm non-flush sensing distance, IP67, terminal block wiring, NO/NC output. If your BOM calls for a 30 mm non-flush sensor with a terminal block instead of a connector, this is the line item. The rectangular body is a straight swap for other 40×40 mm E2Q6 housings; the 118 mm length clears the bracket depth. The 100 Hz switching frequency covers part-in-place and counting on reasonably fast conveyor work. Repeat accuracy is stated at 15% — that rules out precision gap gating, but for general presence detection it's fine.
What the ratings mean for the fit
Non-flush mounting means the face requires free space around it; you can't embed this in a metal bracket without derating the sensing distance. The 30 mm spec is measured with the target approaching axially — in side-approach, actual range drops, but the datasheet's typical performance holds as long as the target size meets the standard factor. Output is listed as NO/NC. Omron typically means a selectable variant: one pair of wiring connections gives NO, another gives NC. Check the label on the body for which terminals correspond — the fixed NO/NC designation means you don't have a universal screw-selectable mode, but the wiring choice gives you the logic you need.
Where the E2Q6N30MF3HOEE sits against the E2Q5N20F3M1OEE
The E2Q5N20F3M1OEE is flush mount, 20 mm, M12 connector, PBT housing, 150 Hz. The E2Q6 here is non-flush, 30 mm, terminal block, 118 mm length.
