The TLP1211 is a photointerrupter that combines an infrared LED, a silicon phototransistor, and an amplifier circuit. It detects the presence of objects by generating a high‑level output when the light path is blocked, with a wide 12 mm gap suitable for large‑size detection.
The datasheet lists maximum ratings, opto‑electrical specifications, mechanical data such as slit width and terminal strength, and detailed precautions for mounting, torque, and material compatibility. It also includes characteristic curves for output current versus detector distance.
| Supply Voltage (Vcc) | 5.0 V (typ) |
|---|---|
| Output Voltage (max) | 28 V |
| Low Level Output Current (IOL) | 16 mA (max) |
| Operating Temperature Range | -25 °C to 75 °C |
| Wide Gap | 12 mm |
| Slit Width | 21.0 mm |
The output becomes high level when the light is shielded.
The screw shall be tightened to a clamping torque of 0.59 N·m.
The low‑level output current is rated up to 16 mA.
