1-Button 900MHz RF Transmitter with 1,800 ft Range, IP68 Waterproof Rating, and 20+ Nonillion Code Combinations
The Seco-Larm HL-951T1-SQ is a single-button 900MHz RF transmitter that provides long-range wireless control for gate operators, door strikes, barriers, and relay-based automation systems. Operating on the 917MHz frequency, it delivers reliable signal transmission up to 1,800 feet (550 m) line-of-sight using an internal PCB antenna that eliminates external antenna breakage. The IP68 waterproof rating means the transmitter withstands complete submersion, making it suitable for outdoor use in any weather condition. It pairs with any Seco-Larm HL-Series receiver for access control and security applications.
The HL-951T1-SQ uses advanced digital modulation with over 20 nonillion possible code combinations (20 x 10^30), making the signal virtually impossible to intercept or duplicate. This level of code security goes far beyond the rolling codes used by consumer gate opener remotes, positioning the HL-Series as a professional-grade solution for commercial and high-security residential gate and door control. The compact form factor (34 x 78 x 12.6 mm) runs on a standard CR-2032 coin cell battery (included).
Where the HL-951T1-SQ Fits
- Commercial gate and barrier control where security personnel and authorized users need a waterproof, long-range transmitter to open gates, barriers, and parking lot arms from up to 1,800 feet away
- Residential driveway gate access where the homeowner needs a compact, pocket-sized remote that operates the gate from the driveway or approaching vehicle without exposing the transmitter to signal cloning or code grabbing
- Wireless relay activation where the transmitter triggers a relay-based device such as a door strike, magnetic lock release, lighting system, or alarm control output through an HL-Series receiver
What the HL-951T1-SQ Delivers
- 1,800 ft (550 m) line-of-sight range: The 917MHz operating frequency provides excellent range and penetration through obstacles. Internal PCB antenna design means no external parts to break, bend, or misalign.
- IP68 waterproof rating: Survives complete submersion in water. The sealed housing protects the electronics from rain, snow, dust, and accidental drops in puddles or pools.
- 20+ nonillion code combinations: Advanced digital modulation generates over 20 x 10^30 possible codes. This level of code complexity makes the signal effectively immune to code grabbing, brute force attacks, and signal duplication.
- Compact single-button design: One button triggers one channel on the paired HL-Series receiver. The slim profile (34 x 78 x 12.6 mm) fits easily on a keychain, in a pocket, or in a vehicle console.
- CR-2032 battery included: Ships ready to use with a standard CR-2032 coin cell. Battery replacement is straightforward with no tools required.
