🛠️ Typical Applications

Conveyor line part detection, 포장 기계, in-position detection, metal part inspection, food washing lines, warehouse sorting.

Not suitable for transparent objects (select BN series for transparent material detection).

⚠️ Cross-Model & 대체 선택

E3FA-RN12: 동일한 사양, PNP 출력, 2 m 케이블

E3FA-RN21: 동일한 매개변수, M12 4핀 커넥터, no long cable

E3FB-RN11: Brass threaded housing, higher IP rating, resistant to cutting fluid

Application Scenarios of E3FA-RN11 (Polarized Retro-Reflective with MSR, M18, NPN, 0.1–4 m)

주요 장점 요약

Polarized red light + MSR anti-mirror reflection; IP67/IP69K washdown resistant; longer sensing range than standard diffuse sensors; wiring only on one side, reflector E39-R1S installed on the opposite side.

한정: For opaque objects only. Not applicable to transparent films, glass bottles or clear PET containers.

1. 자재 취급 & Sorting Conveyors (Most Common Use)

Presence detection, part counting, and in-position monitoring for cartons, tote bins and pallets

Blocking & occupancy detection on roller, belt and chain conveyors

Sorting chute detection: verify carton arrival and missing-part alarm

Pallet & skid detection (4 m long range ideal for wide aisles)

2. 포장기계

Product passing detection & counting on vertical form-fill-seal machines and horizontal flow wrappers

Carton position triggering for case sealers & 달아서 기계

Workpiece positioning for gift box & carton packaging lines

3. 음식 & Beverage Production Lines (IP69K Washdown Compliant)

Conveyor detection for cans, opaque plastic bottles and food trays

Post-wash & post-cook conveyor sections, resistant to splashing and high-pressure rinsing

Position confirmation & no-product alarm for meat & pastry packaging lines

메모: Do not use RN11 for transparent PET bottles or clear films; choose dedicated transparent-detection BN series instead.

4. 금속 가공, Sheet Metal, 스탬핑 & Machining Lines (Core MSR Application)

Detection of sheet metal, 알류미늄 & stainless steel parts (MSR suppresses mirror reflection to avoid false signals)

Blank presence & positioning confirmation for stamping blanking and robot loading/unloading

Part-in-place verification for connector assembly
