433MHz Wireless Remote Switch for Automatic Glass Doors | 203E
Take Full Control of Your Automatic Glass Door — Wirelessly
The Asia-Teco 203E is a professional-grade 433MHz wireless remote control transmitter and receiver system designed for electric automatic glass sliding doors. Whether you're upgrading your home entryway or managing access at a commercial property, this compact unit delivers reliable, responsive wireless control with a robust feature set built for everyday use.
Why Choose the Asia-Teco 203E?
- 4-Function Remote Transmitter: The included 4-key remote lets you control all core door functions — unidirectional open, full open, full lock, and automatic mode — from a single handheld device.
- Wide Voltage Compatibility: Accepts AC/DC 12V–36V power input, making it easy to tap power directly from existing sliding door units with no additional power supply required.
- High-Current Electric Lock Output: Delivers up to 3A (at 12V) for dependable electric lock activation, ensuring positive latching and release every time.
- Built-In Surge Absorber: Protects the unit and connected electronics from return spark and voltage spikes, extending system lifespan.
- Rolling Code Transmission: Microwave-level signal with a roller code ensures your signal is secure and resistant to interception or replay attacks.
- Voice Confirmation Indicator: An audible voice indicator confirms every valid action, so you always know your command was received.
- Unified Induction Signal Input: All induction gate signals are consolidated into the extender, which then outputs commands to both the auto-door mechanism and electric lock — keeping your wiring clean and simple.
- Compact & Easy to Install: Slim profile (123 × 50 × 32 mm, 280 g) with a refined enclosure that mounts neatly into standard door control panels.
- Long Battery Life: Remote control battery rated for ≥8,000 activations, so you won't be replacing batteries constantly.

Frequently Asked Questions
Q: What frequency does this wireless remote control switch use, and what is the typical operating range?
A: The Asia-Teco 203E operates on the 433MHz frequency band, which is widely used for home automation and door control systems. While the exact range can vary depending on the environment and obstructions, 433MHz signals typically provide reliable coverage for most residential and light commercial entryway applications.
Q: Is the 203E compatible with my existing automatic sliding glass door unit?
A: The 203E is designed to work with a broad range of automatic sliding door systems. Its wide AC/DC 12V–36V power input allows it to draw power directly from most door units. It integrates all induction gate signals and outputs commands to both the auto-door mechanism and electric lock. We recommend verifying your door system's voltage and signal requirements before installation.
Q: How secure is the rolling code (roller code) transmission?
A: The rolling code system generates a new encrypted code with every button press, meaning previously captured signals cannot be reused to operate the door. This significantly reduces the risk of unauthorized access compared to fixed-code remotes, making it a solid choice for home security automation.
Q: Can multiple remote transmitters be paired with a single 203E receiver?
A: The 203E supports standard 433MHz pairing procedures, which typically allow multiple transmitters to be registered to one receiver. Please consult the included instruction manual or contact Asia-Teco directly for the exact number of transmitters supported and the pairing process for your specific setup.
