The i.safe MOBILE IS-SW1.1 is the world’s first explosion-protected industrial smartwatch certified for ATEX and IECEx Zone 1/21. Approved for use where flammable gases, vapours and combustible dusts are present, it complements the i.safe MOBILE portfolio and brings dependable wearable safety to oil and gas, chemical processing, pharmaceutical and energy operations.

Coupled via Bluetooth with i.safe MOBILE phones and radios, the IS-SW1.1 functions as a supplementary hands-free display on the wrist. It surfaces important messages, hazard warnings and measured values at a glance, allowing workers to stay informed without reaching for their handset. This wearable convenience keeps teams responsive while their hands remain on the task.

For lone worker protection, the smartwatch monitors vital signs through built-in SpO2 and pulse sensors and can raise an emergency call together with a GPS location. A dedicated SOS key enables a fast alarm in critical situations, while a vibration alarm provides discreet, reliable notification even in noisy environments. NFC supports time recording and access control across the site.

Compact and light at 70 g, the IS-SW1.1 runs ISM-OS 8 on a 1.6 inch display and is rated IP68 against dust and water. The bracelet is tested to a 28 kgf tensile tear-off, and the watch operates from -10 °C to +55 °C, ensuring durable everyday wear in demanding industrial conditions.

    Yes. i.safe MOBILE devices are independently certified to ATEX and IECEx, with many also holding NEC 500, EAC and other regional approvals. The company operates a certified quality management system and is certified to the ISO 14001 environmental management standard. This combination of independent product certification and audited manufacturing processes gives operators confidence in both safety and long-term reliability.

    The range covers intrinsically safe smartphones, rugged feature phones, Android and Windows tablets, push-to-talk over cellular radios and the world’s first Ex-certified industrial smartwatch. Devices are available in Zone 1/21 and Zone 2/22 variants to suit different hazardous area classifications. Many models share a universal ISM accessory interface, allowing barcode scanners, remote speaker microphones and push-to-talk headsets to be added for specific tasks.

    i.safe MOBILE offers devices certified for ATEX and IECEx Zone 1/21, the highest risk classification for explosive gas and dust atmospheres, as well as Zone 2/22 for lower risk areas. Many devices also carry NEC 500 and EAC approvals for international use. Choosing the correct zone variant ensures the device is approved for the specific gas or dust environment in which it will operate.

    The ISM interface is a universal multifunctional connector found on many i.safe MOBILE smartphones and tablets. It allows accessories such as professional barcode scanners, remote speaker microphones, push-to-talk headsets and thermal cameras to be attached, turning a single handset into a flexible field device. This modular approach reduces the number of separate tools a worker needs to carry in the field.

    Yes. The Android devices are Android Enterprise Recommended and zero-touch capable, so they integrate cleanly with mobile device management platforms for remote configuration, security policies and app deployment. As an Android Enterprise Silver Partner, i.safe MOBILE meets Google requirements for certified, enterprise-grade hardware, making the devices well suited to managed fleets across large industrial sites.

    Many i.safe MOBILE devices include a dedicated push-to-talk key and a programmable SOS button, supporting push-to-talk over cellular and lone worker protection workflows. The dedicated PoC radios are designed specifically to replace traditional analogue radios with secure push-to-talk over the mobile network. These features help keep teams connected and protected when working alone in hazardous or remote environments.

    Zone 1/21 devices are certified for areas where an explosive gas or dust atmosphere is likely to occur during normal operation, which is the more demanding classification. Zone 2/22 devices are certified for areas where such an atmosphere is only likely to occur occasionally or for short periods. Selecting the correct range depends on the area classification of the site, so it is worth confirming the zone requirement before ordering.

    i.safe MOBILE is a German manufacturer and world market leader in explosion-protected mobile communications, based in Lauda-Koenigshofen. It develops and manufactures intrinsically safe phones, smartphones and tablets for use in potentially explosive atmospheres and industrial environments, with selected devices now produced entirely in Germany. The company employs more than 130 people and operates internationally through subsidiaries in Singapore and Australia and the Exloc Instruments businesses in the UK and USA.
