Through-beam photoelectric sensor CPG-TF05N3K

infraredcompactintrinsically safe

1. **Naming Rule**
Detection principle: Slot‑type through‑beam; Power supply: DC5‑24V.
Light source: Single‑beam optical axis.
Connection: Cable‑integrated / M12‑A connector (‑A suffix).
‑ **K type: Standard body with standard mounting holes; Cable version: CPG‑TF05N3K / CPG‑TF05P3K; M12‑A version: CPG‑TF05N3K‑A / CPG‑TF05P3K‑A**
‑ **K1 type: Optimized mounting hole layout for M3 screws; Cable version: CPG‑TF05N3K1 / CPG‑TF05P3K1; M12‑A version: CPG‑TF05N3K1‑A / CPG‑TF05P3K1‑A**
‑ **K2 type: Special housing, cable‑only output, no M12 connector, for compact installation space; Cable‑only version: CPG‑TF05N3K2 / CPG‑TF05P3K2; No ‑A (M12) option**
2. **Available Part Numbers**
K‑type:
Cable: CPG‑TF05N3K, CPG‑TF05P3K; M12‑A: CPG‑TF05N3K‑A, CPG‑TF05P3K‑A
K1‑type:
Cable: CPG‑TF05N3K1, CPG‑TF05P3K1; M12‑A: CPG‑TF05N3K1‑A, CPG‑TF05P3K1‑A
K2‑type:
Cable: CPG‑TF05N3K2, CPG‑TF05P3K2; **No M12‑A option**

3. **Detection Principle**
Slot‑type through‑beam. Transmitter and receiver are integrated inside the U‑slot. Output signal is triggered when opaque object blocks the optical axis. Standard detectable object: opaque object ≥2×0.8 mm.
4. **Sensing Range**
Slot width: 5 mm; Hysteresis: ≤0.025 mm.
Indicator: Red LED (lights on when receiving light).
Remark: K/K1/K2 differ only in housing outline and mounting hole layout with identical electrical parameters.
Response frequency: ≥1kHz (K); ≥1.5kHz (K1/K2).
5. **Main Model Versions**
NPN / PNP transistor open‑collector output.
K, K1: Support cable‑integrated and M12‑A (‑A) connector.
K2: Cable‑integrated only, no M12‑A option.
