The Leuze HRTR 3B/66-S,200-S12 (Part Number: 50107245) is a high-precision diffuse reflection photoelectric sensor with active background suppression from Leuze electronic's Series 3B. Engineered as a specialized "Small Light Spot" (-S) variant, this sensor generates a tightly focused optical beam ideal for pinpoint object detection, inspecting miniature semiconductor parts, and scanning through narrow mechanical apertures with unmatched accuracy.

OUTSTANDING FEATURES AND OPERATIONAL ADVANTAGES:
1. Small Focused Light Spot (S Version):
Utilizing an advanced 620 nm red LED light source with precision focusing optics, it creates a small circular light spot with a diameter of just 4 mm at a 100 mm distance. This prevents optical beam spillover and ensures accurate target detection of micro components, thin pins, and wire leads.
2. Active Background Suppression & Low Black-White Error:
Through geometric distance measurement, the sensor completely suppresses reflective or interfering backgrounds beyond the set scanning range. It maintains reliable and consistent detection across dark matte objects and glossy metal surfaces from 5 mm up to 200 mm.
3. Dual Push-pull Digital Outputs:
Equipped with two independent Push-pull outputs that support both Light switching (PNP) and Dark switching (NPN) configurations, offering universal connectivity to standard PLC controller systems without extra interface hardware.
4. Ultra-Fast 1,000 Hz Switching Frequency:
With a swift response time of just 0.5 ms, it operates reliably on ultra-high-speed production lines, ensuring high-speed counting, sorting, and quality inspection without missing parts.
5. Pigtail M12 Connector (200-S12):
Features a 200 mm PVC cable with a 4-pin A-coded M12 connector, enabling fast plug-and-play installation, quick wiring, and minimal machine downtime during maintenance.
6. Rugged Industrial Construction (IP67):
Constructed with durable PC-ABS plastic housing and a scratch-resistant PMMA optical window, offering high shock and vibration resistance across operating temperatures from -30 °C to +55 °C.
