Antenna/IR LED: IR Wavelength 940nm ±20nm, VSWR <2.0:1

Q: What are the main applications of this component in industrial settings?

Used in wireless control systems for machinery, remote monitoring sensors, industrial remote controls, automated guided vehicles (AGVs), and equipment where both RF data transmission and IR remote signaling are required.

Q: How does the dual functionality improve industrial operations?

Provides redundancy (RF for longer range, IR for secure short-range), enables multiple control methods, reduces component count, and simplifies integration in space-constrained industrial devices.

Q: What maintenance is required for this component?

Periodic cleaning of IR lens, inspection for physical damage, verification of RF performance, and checking connector integrity. No regular calibration needed under normal conditions.

Component Specifications

Definition

A hybrid electronic component that integrates an RF antenna for wireless communication (typically in 2.4GHz, 5GHz, or sub-GHz bands) with an infrared LED for short-range optical data transmission or remote control signaling. This component enables both radio frequency and infrared communication capabilities in industrial wireless transmitters, supporting protocols like Wi-Fi, Bluetooth, Zigbee, or proprietary RF alongside IR remote control functions.

Working Principle

The antenna portion operates on electromagnetic wave propagation principles, converting electrical signals to radio waves (transmit) and vice versa (receive). The IR LED emits infrared light (typically 850-940nm wavelength) when forward-biased, with intensity modulated by the input signal to encode data. Both functions share common power and control circuitry but operate on different physical layers.

Materials

Antenna: Copper trace on FR-4 PCB substrate or flexible PCB with nickel/gold plating; optional ceramic dielectric for miniaturization. IR LED: Gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs) semiconductor chip in clear epoxy or silicone encapsulation. Housing: ABS or polycarbonate plastic with RF-transparent window.
