The BTF series from Autionics are ultra‑thin optical sensors designed for both through‑beam and diffuse‑reflection detection. They feature a compact size (≈13 × 24 × 3.7 mm), built‑in protection circuits, and a red LED light source (650 nm). The sensors support multiple output types (NPN/PNP open‑collector) and operate from 12‑24 VDC with low current consumption.
Installation requires the sensor face to be parallel to the target surface, using M2 screws and torque below 0.3 kgf·cm. Adjustment of the optical axis is performed by aligning the indicator LEDs to the desired detection zone. The device is rated IP67, can withstand temperatures from –25 °C to 55 °C (operating) and –40 °C to 70 °C (storage), and meets vibration and shock specifications for industrial environments.
