Overview

The NX series medium resolution area sensors are designed without housing and are intended for applications such as detecting goods in automatic vending machines and objects with irregular shapes. They feature complete electrical protection, LED indicators, and crossed beam detection.

Product Features

• Medium resolution area sensors without housing
• Available with 14 or 16 optics (14 optics cover 132 mm height, 16 optics cover 150 mm height)
• Infrared emission at 880 nm with modulated beams and beam pitch ≥10 mm
• Complete protection against electrical damages including polarity reversal, transient, and short circuit with auto-reset
• LED indicators for supply/emission (yellow), signal level (red), and output state (yellow)
• Emitter and receiver units available separately or as kits
• Axial and right angle optics options
• Output types: NPN or PNP open collector, normally open (NO) or normally closed (NC)
• Models with or without sensitivity adjustment, check input, moisture resistance, and output delay options

Model Variants and Codes

The sensors are identified by model codes indicating optics type, output type, presence of check input, moisture resistance, and output delay. Examples include:

• NX14SR/XAN-A010: 14 optics axial, NPN NO output, with check input, 100 ms delay, sensing distance 0.5–2 m
• NX16SR/XAP-C010: 16 optics right angle, PNP NO output, no check input, no delay, sensing distance 0.5–2 m
• Variants also exist for shorter sensing distances (0.25–0.7 m) with corresponding model suffixes

Technical Specifications

Electrical Connections and Protection

• Emitter connectors: MOLEX 22-05-7038 (3 pins: Positive, Check, Common)
• Receiver connectors: MOLEX 22-05-7038 (1 connector with Positive, Check, Common) and MOLEX 22-05-7048 (2 connector with Positive, Check, Output, Common)
• Electrical protections include polarity reversal, transient suppression, and short circuit auto-reset
• Recommended ESD precautions: disconnect power before handling, discharge static, use metallic screws for installation

Mechanical Dimensions

The sensors have detailed mechanical dimensions provided for both NPN and PNP output models, including mounting hole sizes (ø4 mm) and overall length (~157 mm for 16 optics, ~140 mm for 14 optics). The diagrams specify connector positions and sensor profiles for installation.

Important Notes

• Dark zones exist near emitter and receiver; their size is proportional to the distance between emitter and receiver (X = 0.06 × D)
• PCB is not housed; mechanical and electrical protection must be ensured by the machine structure
• Guaranteed resolution varies across detection area and can be improved with sensitivity adjustment

Summary

The NX series medium resolution area sensors provide flexible, compact, and electrically protected sensing solutions for industrial applications requiring detection of goods or irregular objects. Their modular design without housing allows integration into machine structures with customized protection. Multiple model variants support different sensing distances, output types, and configurations to suit diverse application needs.
