BN665 5G Explosion-Proof Smartphone

Built for hazardous industrial environments with intrinsically safe design, one-touch PTT communication, IP68 protection and long-lasting battery power.

The BN665 is an intrinsically safe 5G smartphone designed for mobile communication and field operations in hazardous industrial environments. It combines cellular voice communication, push-to-talk, application-based video calling, positioning and mobile data capture in a rugged handheld device. Personnel can communicate with control rooms, coordinate with field teams and record equipment conditions without returning to a fixed workstation.

Powered by the MediaTek Dimensity 7050 processor, the BN665 features a 6.6-inch display, 12GB RAM, 256GB storage and a 5000mAh battery. The combination of mobile communications and industrial protection supports inspection, maintenance, operational reporting and field-team coordination across oil and gas, chemical processing and other industrial facilities.

Explosion Protection for Hazardous Areas

Intrinsic Safety: Ex ib IIC T4 Gb

The BN665 features an intrinsically safe design with an Ex ib IIC T4 Gb explosion-protection marking. The ib designation identifies intrinsic safety as the protection method, IIC identifies the explosive gas group, T4 represents a maximum surface-temperature class of 135°C, and Gb is the equipment protection level for explosive gas atmospheres.

This protection marking addresses hazardous gas environments. Equipment selection and use must be consistent with the site's area classification, gas group, temperature class and the operating conditions of the device. Combustible-dust atmospheres and underground mining environments require their own applicable explosion-protection ratings.

5G, Video Calling and One-Touch PTT

Voice and Video Communication

5G connectivity enables the BN665 to carry voice communications, transmit inspection records and exchange images or video from the field. Through compatible video-calling applications, technicians can show live equipment conditions to colleagues or remote specialists, helping maintenance teams assess faults and coordinate work without relying only on verbal descriptions.

Communication services operate over available mobile or Wi-Fi connections. Video calling and enterprise collaboration functions are provided through the applications and services deployed on the handset.

Push-to-Talk Team Coordination

The BN665 supports one-touch push-to-talk communication for rapid coordination between field personnel. With a compatible PTT service, users can communicate with individuals or workgroups using the PTT key. This is particularly useful for shift coordination, inspections, equipment maintenance and operational response.

When connected to an industrial communications platform, PTT conversations can form part of a wider dispatch workflow. Group management, call recording, priority handling and dispatch integration are provided by the relevant PTT or dispatch software.

IP68 Protection and Battery Performance

Rugged Enclosure

The BN665 features IP68-rated protection against dust ingress and water exposure under the applicable test conditions. Its rugged enclosure supports daily operation during outdoor inspections, equipment patrols and maintenance work where dust, moisture and changing weather conditions are common.

IP68 enclosure protection and intrinsic safety address different requirements: the former concerns ingress protection, while the latter addresses ignition risks in classified explosive atmospheres. Both are important when selecting a mobile device for industrial operations.

5000mAh Battery

The integrated 5000mAh battery supports mobile communication and inspection tasks throughout field operations. Battery endurance varies with 5G signal conditions, screen brightness, PTT use, video calls and background applications. Charging and battery handling follow the operating instructions for the explosion-protected device.

Positioning and Digital Fieldwork

Mobile Inspection and Data Capture

The BN665 helps field personnel complete inspections and maintenance reporting at the point of work. Users can capture equipment photographs, enter inspection results, record faults and submit task updates through compatible enterprise applications. Digital work orders link field observations to specific assets, tasks or personnel, reducing repeated manual entry and improving the visibility of work progress.

Personnel identification and access to work records can be incorporated into an organization's mobile workflow through supported authentication and management applications. The available identification method depends on the application and device configuration.

Satellite Positioning and Field Coordination

The BN665 supports satellite positioning with GPS, BeiDou and GLONASS. Location information can be used in outdoor inspection routes, field-task records and team coordination through compatible applications. Position availability and accuracy depend on satellite reception and the surrounding environment; indoor and underground tracking requires a separate location solution where GNSS signals are unavailable.

The smartphone can also serve as a mobile endpoint in inspection, workforce-management and converged communication systems, linking field personnel with operational applications over the available network.

Industrial Applications

Oil and Gas

In refineries, gas-processing facilities and pipeline operations, the BN665 enables voice and PTT communication alongside digital equipment checks and field reporting. Workers can share inspection results and photographs with supervisors while moving between approved operating areas.

Chemical Processing

Chemical plant personnel can use the BN665 to report equipment status, update maintenance work orders and coordinate operating tasks. Its intrinsically safe design supports mobile communication in gas-hazardous environments that match the device's protection classification.

Offshore Facilities

For offshore inspections and maintenance, the BN665 provides a handheld communication and reporting terminal for field crews. Voice calls, PTT and compatible video applications help personnel exchange information with control rooms and technical support teams over available networks.

Power, Utilities and Industrial Maintenance

Maintenance teams working across utility facilities and industrial sites can use the BN665 for equipment inspections, location-linked work records and rapid team communication. Its IP68 enclosure and 5000mAh battery are suited to mobile tasks carried out away from fixed workstations.

FAQ

What explosion protection does the BN665 provide?

The BN665 features Ex ib IIC T4 Gb intrinsic safety protection for explosive gas atmospheres. The marking identifies the protection method, gas group, temperature class and equipment protection level. The device is selected and operated according to the hazardous-area classification and applicable operating requirements.

Does the BN665 support video calling and PTT?

Yes. The BN665 supports one-touch PTT communication with a compatible PTT service and video calling through compatible applications. These functions help field personnel communicate with teams, control rooms and remote specialists.

Can the BN665 connect to an industrial dispatch or inspection platform?

The BN665 can run compatible mobile applications for PTT communication, inspection reporting and task management. Group calling, dispatch workflows, data synchronization and reporting functions are delivered through the connected application platform.

Can the BN665 be used in hazardous gas areas?

The BN665's Ex ib IIC T4 Gb marking is intended for explosive gas atmospheres, with the Gb equipment protection level associated with Zone 1 equipment selection. Use in a classified area must match the applicable gas group, temperature class and operating conditions. Explosive-dust and underground mining environments require separate protection classifications.
