The Autonics BTF1M-TDTD Ultra-Compact, Thin Type Photoelectric Sensor is engineered for space-constrained automation environments. Using a through-beam sensing type, it delivers a reliable 1m sensing distance for opaque targets as small as Γ2mm. The 650nm red LED light source provides high visibility for alignment, while the ultra-fast 1ms response time ensures accurate detection on high-speed conveyor lines and automated machinery.
Operating on a stable 12β24VDC Β±10% power supply, the BTF1M-TDTD consumes only 20mA across its emitter and receiver, making it energy-efficient. Its NPN open collector output allows seamless integration with PLCs and industrial control systems. The robust IP67 protection rating safeguards the sensor from dust, oil, and water ingress, making it dependable in harsh production environments. High-quality materials, including polybutylene terephthalate and SUS304 stainless steel, ensure mechanical strength and longevity.
This model operates reliably between -25Β°C to 55Β°C and withstands ambient light interference up to 10,000lx sunlight and 3,000lx incandescent light. A 2m cable connection and included stainless-steel bracket with M2 bolts make installation fast and secure.
