The Autonics BTS15-LDTL Ultra-Compact, Slim Type Photo Sensor is built with a convergent reflective sensing type that delivers precise and consistent detection within a sensing distance of 5 to 15mm. It accurately detects opaque and translucent objects with a minimum size of just Γ0.15mm, making it ideal for fine-part detection in compact systems. Operating in Light ON mode, this sensor uses a 650nm Red LED light source and provides fast signal processing with a 1ms response time. The unit runs on a standard 12β24VDC Β±10% supply and consumes only 20mA, outputting via an NPN open collector for smooth integration with PLCs and control units commonly used in industrial automation.
The BTS15-LDTL is designed for harsh industrial conditions, housed in a durable polybutylene terephthalate body and a high-clarity polymethyl methacrylate sensing surface. Mechanical parts such as the bracket (SUS304), bolts (SWCH10A carbon steel), and sleeve are engineered for corrosion resistance and long-term mechanical stability. The sensor is rated IP67, ensuring protection against dust, oil, and water sprayβideal for demanding shop floors and manufacturing lines. It performs reliably under ambient illumination up to 10,000lx and within a temperature range of β20Β°C to 55Β°C. With a 2-meter cable (Γ2.5mm) and included mounting accessories, it allows for quick and secure installation, even in narrow control panels. The 15% hysteresis limit at maximum distance ensures accuracy and repeatability, vital for quality-sensitive automation.
The BTS15-LDTL is widely deployed in label positioning, part presence verification, robotic gripper detection, and compact inspection systems. Its slim structure makes it perfect for mounting inside SMT equipment, mini conveyors, medical device assembly lines, and electronics production units. Indian maintenance engineers value its no-calibration setup and resistance to dust and moisture, while automation design teams trust its precision in low-clearance environments. Whether used in fast-moving packaging lines or electronics pick-and-place systems, this sensor helps reduce false positives while improving throughput accuracy.
