🧩 Application Scenarios

Pneumatic pressure detection, vacuum adsorption (this model is positive pressure; select E8F2-AN0C for negative pressure), fixture pressure confirmation, air source pressure monitoring, pressure judgment in semiconductor/electronics production, OK/NG pressure judgment with PLC.

⚠️ Alternative Selection Recommendation (새로운 프로젝트)

E8F2 discontinued. 오므론 recommends next-generation E8CC series for replacement with same range 0~100kPa NPN digital pressure sensor.

Replacement checkpoints: pressure port, NPN output type, 1~5V analog signal, 장착 브래킷, 배선 정의.

비교표: E8F2-A01C (원래의) vs E8CC-A01C (Official Recommended Replacement)

중요사항: E8FC is flow sensor and cannot replace E8F2 pressure sensor. The official direct replacement for E8F2-A01C is E8CC-A01C (0~100kPa, NPN, 2m 케이블). E8CC pressure sensor and E8FC flow sensor are frequently confused.

상태	단종 2024, 재고 / used only	단종, limited stock; E8PE recommended for new projects	E8CC also phasing out; select E8PE for new machine design

Replacement Implementation Guide

✅ No air tube change, no PLC program modification. Only replace mounting bracket, re-set pressure threshold and zero calibration after power on.

⚠️ E8CC slim strip housing vs E8F2 cube housing. Mounting hole incompatible, original E89-F3 bracket cannot be reused. Use dedicated E8CC bracket.

Long-term Alternative for New Projects (E8PE Series)

When E8CC stock is exhausted, E8PE-B01C (0~100kPa, NPN, M12 커넥터, IO-링크, IP67) is recommended for new machines.

차이점: M12 connector instead of pre-wired cable; analog output changed to 4-20mA, PLC analog wiring adjustment required. Prioritize E8CC-A01C for direct retrofit of existing equipment.

Common Pitfall Reminder

E8FC is liquid flow sensor (for cooling water / oil flow + 온도 측정), NOT pressure sensor. Do not confuse E8CC pressure sensor and E8FC flow sensor during model selection.

Brief Explanation

Switch judgment (OK/NG)：Both have identical repeatability. Accuracy difference negligible for pneumatic pressure threshold replacement.
아날로그 획득 (PLC AD input)：E8CC analog output has better overall accuracy (±3%FS vs E8F2 ±5%FS).
Display reading：Identical specification at ambient 25℃. E8CC error increases at low temperature or near 55℃ high temperature.
Minor range difference: E8F2 0~~100kPa; E8CC 0~~98kPa, acceptable equivalent in engineering.

Output Signal Comparison Table: E8F2-A01C vs E8CC-A01C

Both have identical output configuration: 2-channel independent NPN switch + 1 channel 1～5V analog voltage signal. No PLC interface modification required for retrofit.
