Tough industrial operator – Up to 1300 operations a day – Machined steel gears – Heavy duty bearings – Adjustable speed control
The Sentinel R21 in-ground operator is a reliable robust swing gate opener suitable for large industrial gates up to 3500 mm wide and rated to 1300 operations a day.
This operator is installed in-ground under the gate hinge and can open to 180 degrees. The R21 is particularly useful in situations where the gates are fitted to large brick pillars and conventional linear gate openers cannot be used.
Traffic flow can be more efficiently managed with option to have various operating speeds depending on the traffic type i.e. slow for large trucks and faster for cars.
The Sentinel R21 In Ground Swing Gate Operator features include:
Strong and robust: The gearbox with machined steel gears and heavy duty bearings is enclosed in a die cast casing which is waterproof to IP67.
Smooth operation: The absolute encoder constantly monitors the speed and position of the gate. This allows the control panel to accurately ramp down the speed on closing providing a smooth operation and longer life.
Precision speed control: The option to have various operating speeds aids the flow of traffic, slow for large trucks and faster for cars.
Security: The strong gearbox and self locking mechanism prevents damage from vandalism as the gate cannot be forced.
Reliable and efficient: The revolutionary brushless motor provides much greater efficiency – with ultra low power consumption.
Essential safety features are covered: Optional loop detectors and safety beams ensure vehicles and pedestrians alike are protected.
Foundation box: Compact and robust foundation boxes available with cover made from hot galvanized steel and AISI 304 stainless steel.
Intelligent release: can be released internally and externally using a standard lever or key release system.
Mechanical adjustable stop when closing and opening.
Included in the kit: two Nova radio control transmitters and one receiver, all mounting brackets, drive arms and external key release.

Automatic Swing Gate Openers
Discover our range of high-quality, reliable automatic swing gate openers:
Linear Swing Gate Openers: are possibly the most commonly used swing gate operators. Their popularity stems from their affordable price and simple installation, simply attaching to the gate from the post. Our range of linear swing gate operators provide a reliable and safe security solution for all commercial, industrial and residential sites.
In-ground Swing Gate Openers: our durable underground swing gate operators are another very popular for situations where aesthetics are important or where conventional linear swing gate openers are impractical. While installation is more complex this type of swing gate operator delivers invisible, powerful and reliable operation for large industrial gates.
Crank Arm Swing Gate Operators: an articulated arm or crank arm motor are an ideal automatic gate opener for smaller gates or gates with larger pillars that would struggle to fit the linear style swing gate opener. A versatile opener, providing automation for most types of swing gates, our intensive-use, heavy duty swing gate openers offer high duty cycle and low power consumption.
Solar Swing Gate Openers: many of our automatic swing gate openers are able to accommodate solar power for use in remote locations or where mains power isn’t available.

Our industrial remote control equipment consists of radio remote control products designed to work efficiently with our extensive range of automatic gates and many other types of industrial equipment.
Remote radio controls for industrial applications: Our remote controls for gates offer a high level of security. Industrial radio remote controls are a convenient method of controlling automatic gates and doors. Our radio remote controls can also be used to activate other equipment or control any number of electrical devices.
Long-range radio remote controls: our long-range remote control systems suit locations that experience transmission problems. Frequently used by farmers, plant operators, quarries, and mines, long-range radio remote controls are used to control gates, garage, and industrial door entry systems or switch other equipment on/off.
4GSM Gate Openers: ideal for both domestic and commercial use and suitable for small to medium-size buildings, GSM gate openers allow you to control your automated gate via SMS, giving complete control of your gates at your fingertips from anywhere.
Wireless Transceivers: this type of industrial radio control system produces a standalone network of devices that inter-communicate, enabling an always-connected, secure wireless environment that can remotely monitor and control virtually anything.
Competitively priced, all our door and gate safety equipment solutions comply with international standards. For reliable accurate detection select from our extensive range of loop detectors and logics, vehicle detectors, safety beams, and safety light curtains to secure your gate or entrance.
Loop Detectors:Considered one of the most effective methods of vehicle detection, loop detectors prevent boom gates or garage doors from closing while a vehicle is in the roadway.
Microwave Vehicle Detectors: Our vehicle detection devices provide an efficient and cost-effective alternative to loop detectors and safety beams. Designed for parking and access control applications these vehicle detectors are mounted above ground, on walls and ceilings, providing the flexibility to accommodate many scenarios.
PE Safety Beams: Commonly used as safety devices to prevent industrial doors or gates closing on pedestrians or vehicles. The latest PE safety beam designs are wireless and do not need cables to each side of the driveway saving time and money.
Safety Light Curtain: Used in situations where maximum coverage is required our safety light curtain’s multiple beams are spaced to ensure the area is covered. Easy to install and weatherproof design makes it suitable for all types of entrances including gates, boom gates, and doors.
Traffic lights and warning lights are a fundamental part of automated access control systems which use boom gates, sliding gates and swing gates, as they provide a clear indication that the gates are installed and in operation.
Traffic Lights: our traffic are suitable for commercial or industrial applications around boom gates, parking barriers and sliding gates. We can provide various combinations of lights including 3 aspect (red/green/amber) and walk/don’t walk indicators.
Warning Lights: there are many uses and options are available to suit. Hazard beacon lights provide visual safety awareness around moving machinery and structures such as automated gates, doors, safety barriers, lifting equipment, and service vehicles.
Warning flashing lights and sounders: are also used in industrial locations, such as warehouses, to alert forklift operators that pedestrians are in their work area, and alert pedestrians they are entering a potentially dangerous area, and to use caution. Low power consumption and all-weather versatility of LED warning lights make them a good choice for virtually any unsafe situation.
In addition to our standard range of traffic lights and warning lights below we have access to many types and combinations of voice sounders, sirens and warning lights - contact us for assistance regarding your requirements
