XL-ITR1100 SMD LED — Technical Specifications & Design Guide

📌 Product Overview

The XL-ITR1100 is a transmissive photoelectric switch manufactured by XINGLIGHT, designed to function as a reliable obstacle detection sensor. 📦 It integrates a Gallium Arsenide infrared emitting diode and a silicon phototransistor detector, typically separated by a slot to detect the presence of objects. The device operates at a peak wavelength of 940nm, making it suitable for applications requiring immunity to visible light interference. 💡 Design priorities for this model include low forward voltage drive and high photosensitivity, ensuring responsive triggering in compact electronic assemblies.

🛠 Typical Applications

  • Slot Machines & Gaming: Utilized for coin detection and mechanism position sensing due to fast response times.
  • Office Automation: Integrated into fax machines and scanners to detect paper jams and document feed alignment.
  • Home Appliances: Used in small appliances for door or lid open/close status detection.
  • Automatic Sensors: Ideal for non-contact safety switches and limit switches in consumer electronics.
  • Industrial Controls: Suitable for simple limit switching where robustness and low power consumption are required.

⚡ Key Technical Specifications

The XL-ITR1100 is engineered for high sensitivity and speed. The following table summarizes the electro-optical characteristics under standard test conditions (Ta=25°C):

💡 Soldering Constraint: Lead soldering temperature must not exceed 260°C, and the iron should be kept >2mm from the epoxy body for a maximum of 5 seconds to prevent degradation.

📦 Package, Dimensions & Assembly Notes

The XL-ITR1100 features a standard transmissive slot-type structure, likely utilizing a through-hole mounting style for mechanical stability (inferred from lead soldering specs). ⚙️ The outline dimensions are critical for mechanical integration into chassis or PCB slots; all drawings without specific tolerances should be assumed to be ±0.3mm.

  • Moisture Sensitivity: The component is classified as MSL (Moisture Sensitivity Level) 2.
  • Assembly: Ensure proper alignment during wave soldering or manual soldering to avoid bridging the emitter and detector leads.
  • Environment: The packaging utilizes moisture-proof and anti-static foil bags to maintain ESD safety and prevent shelf-life degradation.

🚢 Sourcing & Supply Considerations

For procurement teams and engineers, verifying the voltage grading codes (R2-4) and current transfer codes (IC23-33) is essential for batch consistency. 🔍 When sourcing XL-ITR1100 units, confirm that the supplier provides authentic XINGLIGHT products with valid RoHS and Lead-Free certifications. Sample evaluation should focus on the saturation voltage variance to ensure compatibility with your drive logic. For high-volume projects, checking lead times and moisture-proof packaging integrity upon arrival is recommended to mitigate SMT assembly defects.

❓ FAQ

Q: What is the peak emission wavelength of the XL-ITR1100?
A: The device emits infrared light at a peak wavelength (λP) of 940nm, which is invisible to the human eye and minimizes interference from ambient visible light sources.

Q: Can the XL-ITR1100 be used in high-temperature environments?
A: The component is rated for an operating temperature range of -25°C to +85°C. It is suitable for standard commercial and industrial environments but should be evaluated carefully if placed near high-heat sources like power transformers.

Q: What is the maximum Forward Current allowed for this sensor?
A: The Absolute Maximum Rating for Continuous Forward Current (IF) is 50mA. However, a Peak Forward Current (IFP) of 1000mA is permissible, provided the pulse width is ≤100μs and the duty cycle is 1%.

Q: How do I ensure the sensor is authentic and compliant?
A: Look for the Pb-Free (Lead-Free) and RoHS markings on the packaging. Additionally, verify the Moisture Sensitivity Level (MSL) marking, which is Level 2 for this model, to ensure proper storage and handling procedures.

Q: What is the response time of the XL-ITR1100?
A: Both the Rise Time (tr) and Fall Time (tf) are typically 15μs. This fast response time makes it suitable for detecting small objects or high-speed operations in printers and slot machines.
