Products Description
1206 Top View Dome Lens 30 Degree Narrow Angle 940nm SMD IR Emitter
Model Number:AL-S1206IRC-VI-3DP914
The AL-S1206IRC-VI-3DP914 is a top-view non-side-emitting 1206 packaged SMD infrared emitter, totally different from side-view 0802/1206 lateral IR LED in market. Equipped with molded convex dome lens on top surface, this 940nm IR chip focuses infrared ray vertically upward within fixed 30° narrow divergence angle, making it the preferred transmitting source for vertical alignment optoelectronic sensing modules.
Most conventional 1206 IR components adopt flat top or side-emitting molding, either with wide scattered beam or lateral light output that cannot realize vertical pinpoint signal emission. Our dome top mount structure guides all infrared energy shoot straight up, matching vertically installed phototransistor receivers perfectly. Standard 1206 SMD footprint supports full-automatic SMT reflow soldering on PCB, greatly improving assembly efficiency for electronics manufacturers producing sensing equipment.
Core Advantages
1.Top vertical emission design: Zero side light leakage avoids signal interference, ideal for compact multi-channel sensor layouts.
2.Dome lens focused beam:30° narrow-angle output improves detection precision when paired with matched phototransistors.
3.Excellent long-term stability: Premium chip and lead frame keep low luminous decay after long continuous operation.
4.Standard 1206 footprint: Direct replacement for conventional 1206 IR LEDs without PCB redesign cost.

About Us
FAQ
Q1: Is this 1206 IR LED side emitting like 0802 lateral IR diode?
A: Definitely no. It's top-view vertical emission SMD IR, all infrared light emits upward from top dome lens with no side output, totally different from side glowing 0802/1206 lateral IR products. Side-emitting IR suits side alignment detection, our top mount model is for vertical up-down transmit-receive matching.
Q2: Can this 30° dome 940nm LED be driven on 5V circuit board?
A: Yes, typical Vf=1.2V@20mA, just add matching current limiting resistor on 5V circuit to fix working current around 20mA for stable performance.
Q3: Can I get samples to test vertical emission effect before bulk order?
A: Free samples within 50pcs are available, only shipping cost needed, samples dispatched within 2 working days after confirmation.
Q4: Can you customize 850nm version with same 1206 top dome package?
A: Yes, we can produce 850nm/870nm/950nm top-view non-side emitting 1206 IR LED as customized order, small batch prototype acceptable.
