The i.safe MOBILE IS940.1 heads our mining list because one model range covers both the face and the plant. Its IS940.M1 mining version is certified for Group I under ATEX (marking I M1 Ex ia I Ma, certificate EPS 25 ATEX 1 003 X) and IECEx (Ex ia I Ma, IECEx EPS 25.0003X). Category M1 means the tablet may stay powered when firedamp is present, so a crew does not have to switch it off to keep it compliant. Above ground, the standard IS940.1 is intrinsically safe to Ex ib IIC T4 for Zone 1/21 with dust group IIIC, under ATEX and IECEx, with Class I Division 1 (Groups A to D) and Class II Division 1 (Groups E to G) listings for North America, so one tablet range serves the shaft and the processing plant.
It is a 10.1-inch Android 14 tablet with a 50 MP camera for photographing equipment and faults, 5G and Wi-Fi 6, NFC and a freely programmable red key that can be set to SOS or a lone-worker app. It is IP68 and MIL-STD-810H, usable with gloves, and i.safe states security updates until Q4 2032. The standard IS940.1 may be charged in the hazardous area, within a charging temperature of 0 °C to +45 °C, and its IECEx certificate also covers the IS-DS940.1 docking station that i.safe lists for charging there.
Plan around the limits. The M1 version is a separate certificate, and our data does not give its charging conditions, ambient range or ingress rating, so confirm them with i.safe. The standard model is T4, which suits most gases but not those that ignite below 135 °C, it is not certified for Zone 0, and it weighs 1,059 g. Our data lists no national mining approvals for the M1 version beyond the ATEX and IECEx certificates named, so check what your mine regulator requires.
