XB-TD511A Speed Gate – Smart Pedestrian Access Control for Modern Buildings
Elegant Design, Reliable Access Control
The TD511A Speed Gate is a premium pedestrian access control solution designed for modern office buildings, commercial complexes, residential lobbies, business parks, and other high-end entrance areas.For many access control projects, a turnstile is no longer only a physical barrier. It also needs to match the building design, integrate with different authentication systems, handle busy pedestrian traffic, and provide a safe and comfortable passage experience.
The TD511A is designed around these requirements.Its slim cabinet, customizable materials and finishes, brushless servo motor, multiple infrared sensors, anti-tailgating control, and flexible access interfaces allow system integrators and project contractors to build a professional entrance management system without sacrificing architectural appearance.
Designed for High-End Building Entrances
The TD511A uses a bridge-style structural frame designed to maintain stability under repeated use and external impact.
The main cabinet is manufactured from 1.5 mm cold-rolled steel with painted and baked finishing, combined with molded aluminum alloy components. Different materials can also be selected for the top cover, including CNC-machined aluminum alloy and marble-effect materials.Colors and materials can be customized according to the architectural environment of the project.
This makes the gate particularly suitable for locations where the entrance equipment becomes part of the overall interior design, such as:
- Corporate headquarters
- Commercial office buildings
- Premium residential buildings
- Business parks
- Hotel and apartment lobbies
- Indoor access control areas
- Covered outdoor entrances
Flexible Integration with Access Control Systems
Different projects use different identity verification methods.
The TD511A is designed to work with a variety of third-party access control devices, including:
- IC / ID card readers
- ID document readers
- QR code readers
- Face recognition terminals
- Other access control systems
The controller provides left-open, right-open, fire alarm, TTL and RS485 interfaces, making system integration easier for access control contractors and solution providers.
An optional hidden 2MP starlight binocular wide-angle camera can also be integrated into the gate for face recognition applications, helping create a cleaner all-in-one entrance design.
Faster Passage During Busy Hours
Entrance congestion can quickly become a problem in office buildings and other high-traffic facilities.
The TD511A supports an estimated passage rate of 20–60 persons per minute, depending on pedestrian conditions and operating mode.A passage memory function allows the system to remember the number of authorized users after multiple consecutive authentications. The gate can remain open until the authorized pedestrians have passed and then close automatically.
The gate can also operate in different passage modes, including:
- Controlled entry and controlled exit
- Controlled entry with sensor-triggered exit
- Adjustable opening and closing speed
- Normally open mode during peak periods
This flexibility helps operators adapt the gate operation to different pedestrian traffic conditions.
Anti-Tailgating for Better Entrance Security
Unauthorized people following closely behind an authorized user is a common challenge in office buildings and controlled facilities.The TD511A uses anti-tailgating tracking control technology to monitor pedestrian passage.
Only authorized users are permitted to pass. If an unauthorized person attempts to enter the lane, the system can trigger an audible alarm together with flashing light indicators on both sides of the passage.This helps security teams identify abnormal access behavior without relying entirely on manual supervision.
Multiple Safety Protections for Pedestrians
Safety is especially important when speed gates are installed in locations with frequent pedestrian movement.
The TD511A is equipped with 8 pairs of infrared detection sensors as standard, with support for expansion to 12 pairs.The infrared sensors help detect pedestrian positions and provide anti-pinch protection during passage.
The gate also includes an obstacle rebound function. If the door wing encounters resistance during closing, the motor stops automatically. Under specified conditions, the gate can rebound to the open position to reduce the risk of injury.For additional protection against forced entry, the mechanism uses a precision clutch and locking structure. When an unauthorized person pushes or impacts the gate without an opening command, the system can lock after the swing arm reaches a preset angle, automatically reset and trigger an alarm.
This design helps reduce both pedestrian injury risks and mechanical damage caused by repeated impacts.
Emergency and Fire Safety Support
Emergency evacuation is an important consideration in commercial access control projects.The TD511A supports a fire alarm interface. When a fire signal is triggered, the door wings automatically open to provide an evacuation passage.If power is lost, the gate wings also automatically open so pedestrians can pass freely.These functions allow the speed gate to work as part of a building's wider entrance and emergency management strategy.
Remote Control and Easier Operation
The main controller includes an LCD screen with Chinese and English setting menus, allowing technicians to configure operating parameters directly on the equipment.
When connected through compatible face recognition equipment to a cloud platform, the gate can also support functions such as:
- Remote parameter configuration
- Remote entry opening
- Remote exit opening
- Peak-hour normally open mode
An optional wireless receiver and remote controller can also be used for single entry opening, single exit opening or normally open operation.
This provides additional flexibility for reception desks, security teams and building operators.
Customizable for Different Projects
Different buildings have different entrance widths, interior styles and access control requirements.
The TD511A offers a clear advantage for project-based deployment because several elements can be adapted to the application.
Passage Width
Standard clear passage width can be configured between:
550–1200 mm
For clear passage widths above 1000 mm, the gate panel requires a hollowed design according to the product specification.
Wider lanes can therefore be considered for projects requiring easier pedestrian movement or larger access openings.
Materials and Appearance
The cabinet color and surface materials can be customized according to the design of the building.
Optional top-cover materials include:
- CNC aluminum alloy
- Marble-effect material
This allows system integrators, architects and project contractors to better coordinate the access gate with the surrounding environment.
Reliable Brushless Servo Motor
The TD511A uses a DC brushless servo motor.
The mechanism performs a self-check after power-on and is designed for stable, precise door movement and long service life.
The master-slave architecture is also simplified. The brushless controller uses a one-to-one control structure, while the main and secondary cabinets require only a four-core connection cable.
This helps simplify on-site wiring and future maintenance.
Electrical safety is further supported by a built-in leakage protection device, while the operating voltage of the relevant electrical modules inside the equipment does not exceed 24V.

A Speed Gate Built for Project Integration
For B2B access control projects, selecting a speed gate is not simply about choosing a door that opens and closes.
The equipment must balance:Security, pedestrian safety, throughput, system compatibility, architectural design and long-term maintenance.
The TD511A combines these requirements in one slim pedestrian access platform.With support for card readers, QR code readers, face recognition, RS485 communication, fire linkage, anti-tailgating detection, pedestrian counting and customizable appearance, it can be integrated into a wide range of modern building access control projects.For distributors, access control integrators, contractors and property management projects, XIBING can provide configuration support according to passage width, authentication method, installation environment and project requirements.
