🧩 Application Scenarios
Pneumatic pressure detection, adsorbție în vid (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 (Proiecte noi)
E8F2 discontinued. OMRON 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, suport de montare, definirea cablajului.

Tabel de comparație: E8F2-A01C (Original) vs E8CC-A01C (Official Recommended Replacement)
Notă importantă: E8FC is flow sensor and cannot replace E8F2 pressure sensor. The official direct replacement for E8F2-A01C is E8CC-A01C (0~100kPa, NPN, 2m cablu). E8CC pressure sensor and E8FC flow sensor are frequently confused.

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, conector M12, IO-Link, IP67) is recommended for new machines.
Diferențele: 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 + temperature measurement), 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.
- Analog acquisition (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

Key Summary
✅ Same signal types: 2-channel NPN switch + 1~5V analog voltage, no PLC program change needed.
⚠️ Different wire color mapping, most common field replacement error point.
✅ Analog is voltage output, NOT 4-20mA current signal.
