SICK GTB6‑N1241 Background Suppression Photoelectric Sensor, NPN Output 5–450 mm Adjustable Range IP67 2m Cable G6 Industrial Sensor

SICK GTB6‑N1241 Adjustable Background Suppression Sensor for Flexible Factory Automation

Procurement Matching & Inventory Advantages

Universal Field Replacement Compatibility

SICK GTB6‑N1241 features standard G6 series dimensional layout and electrical parameters, supporting direct replacement for legacy miniature photoelectric sensors. Unified industry-standard specifications eliminate customized adaptation work during equipment maintenance. Stable factory calibration reduces on-site tuning workload, helping factories simplify spare-part inventory and lower stocking costs.

Wide Range Coverage Reduces Model Selection Complexity

With an extended 5 mm to 450 mm adjustable sensing distance, SICK GTB6‑N1241 covers multiple short and medium-range detection demands. A single sensor model replaces fixed-range sensors for different positioning tasks. Flexible range adjustment fits variable production layouts, avoiding repeated model selection for upgraded or modified automation lines.

Optimized Optical Detection & Anti‑interference Performance

Precision Background Suppression Technology

SICK GTB6‑N1241 adopts advanced background suppression optical design to ignore interfering background surfaces. The focused infrared light beam locks target objects accurately, regardless of reflective conveyor belts, metal frames or uneven mounting backgrounds. This optical structure drastically cuts false triggering rates for high-precision positioning and counting operations.

Visible Alignment & High‑speed Response

Equipped with PinPoint LED light source, SICK GTB6‑N1241 provides clear light spot visualization for fast field alignment. Millisecond-level response speed and 500 Hz switching frequency support stable detection on high-speed moving production lines. Consistent signal output maintains operational accuracy during long-duration continuous automation cycles.

Electrical Specifications & Circuit Reliability

Standard NPN Output & DC Power Design

SICK GTB6‑N1241 operates on 10 V to 30 V DC universal industrial voltage. Built-in NPN open-collector switching output matches mainstream PLC input logic, with 100 mA maximum load capacity for stable signal transmission. Standard electrical configuration ensures seamless compatibility with new and retrofitted factory control systems.

Complete Built‑in Circuit Protection

Reverse polarity protection and short-circuit protection guard internal circuit components of SICK GTB6‑N1241. These safety mechanisms prevent damage from incorrect wiring or instantaneous current surges. Robust electrical design guarantees uninterrupted sensor operation under daily industrial power fluctuation conditions.

Mechanical Structure & Field Deployment Features

Durable Plastic Housing & Fixed Cable Layout

SICK GTB6‑N1241 uses high-strength ABS and PC composite housing for solid structural durability. Integrated metal threaded inserts enhance mounting stability against long-term vibration. The 2-meter fixed 3-core cable structure enables direct wiring without extra connectors, simplifying field circuit arrangement and reducing loose connection risks.

IP67 Industrial Environmental Resistance

IP67 ingress protection rating shields SICK GTB6‑N1241 from workshop dust, debris and accidental water splashes. The fully sealed internal structure adapts to standard indoor industrial environments. Stable performance sustains within -25 °C to +55 °C temperature range, fitting seasonal ambient temperature changes in factory workshops.

Core Industrial Application Scenarios

Packaging & Logistics Automation

SICK GTB6‑N1241 performs reliable object counting, product presence confirmation and package positioning on packaging lines. Background suppression function detects transparent packaging and irregular-shaped products stably. Adjustable sensing distance adapts to different product sizes on sorting and conveying equipment.

Precision Assembly Line Monitoring

Small component detection, part missing inspection and station positioning verification represent key uses for SICK GTB6‑N1241. Compact housing fits narrow assembly machine gaps. High anti-interference capability ensures precise detection in dense mechanical operation environments.
