1. **Naming Rule (digit 4‑digit 11 definition)**
(1) digit 4: Detection principle
T: Through‑beam
(2) digit 5: Light source type
R: Red light
(3) digit 7: Sensing distance (unit: mm; use “m” for distance over 1 m): 20 m
(4) digit 8: Output type
N: NPN, P: PNP
(5) digit 9: Output status
3: Switchable Light‑ON / Dark‑ON
(6) digit 10: Cable / connector requirement
‑ Blank: Pre‑formed cable
‑ A: M12 connector type
(7) digit 11: Special requirements
No special suffix for this subgroup.
