Ex-Proof Mobile Phone Distributor in Switzerland

The IS-04Z1 is an intrinsically safe Android handset designed for solvent and powder atmospheres, from a production building in Basel or Visp to a loading rack at Cressier and a digester hall at a cantonal wastewater works. Petroleum and motor fuels account for 43% of energy consumed, electricity 26% and gas 15%, with households and transport each using about one third and manufacturing and services each just under one fifth. An Ex-proof mobile phone distributor in Switzerland would carry the IS-04Z1 to these buyers once certification completes.

Short answer. Switzerland has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.

For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

Field notes · Switzerland

More about Switzerland that matters for portable equipment

Switzerland: logistics and access

The three Rhine ports around Basel handle about six million tonnes and over 120,000 containers a year, roughly 10% of Swiss imports and a third of the country's mineral oil products.

Switzerland: infrastructure

Switzerland relies mainly on hydroelectric power, nuclear power and natural gas, and plans to phase out its five nuclear power plants as they reach the end of their lives, with 2044 given as a phase-out date.

Switzerland: industry on the ground

Basel is Switzerland's main pharmaceutical centre, home to both Novartis and Roche.

Switzerland: industry on the ground

Machinery, chemicals, vehicles and metals are leading industries, so classified areas occur more in chemical and pharmaceutical plants and process industry than in oil and gas.

The term · Ex-proof

What “Ex-proof” means for a smartphone

“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.

The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.

In Switzerland. A Swiss marking check reads II 2 G Ex ib IIC T4 against solvent charging points, dryers and centrifuge areas, which are the dominant Zone 1 case. Group IIC and T4 are what such areas are normally specified against. Dust in active ingredient handling puts Zone 21 metres from a gas zone.

The route · distribution

Distributing the IS-04Z1 in Switzerland

A distributor for Switzerland would carry the IS-04Z1 after certification completes; the Q4 2026 launch is the planning date and no appointment has been made. SAMS reviews applicants one by one and prefers companies with their own Ex-competent technical and service staff, since certified devices must not be repaired outside approved channels.

What SAMS looks for in a partner

Operator relationships
Existing supplier registrations or a clear route to them with the main operators and contractors in Switzerland.
Ex-competent staff
People who understand zone classification, markings and the conditions of a certificate.

And equally important

Local-language support
Documentation, training and helpdesk in the languages the workforce uses.
Service capability
Spares, battery replacement and repair routed through SAMS-approved channels.
Questions · Switzerland

Frequently asked questions

Can we buy an Ex-proof mobile phone in Switzerland today?

No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.

What does an Ex-proof mobile phone in Switzerland cost?

SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.

What Ex marking will the IS-04Z1 carry?

The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.

Which sites in Switzerland does this cover?

The market guide for Switzerland covers Basel and Schweizerhalle, Visp, Monthey, Kaisten and the Fricktal, among others. Site-level pages are linked below.

How do I become a SAMS distributor for Switzerland?

Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Switzerland.

Which Swiss industries need intrinsically safe phones?

Chemical and pharmaceutical plants, fuel depots, gas networks, wastewater and biogas plants, and some manufacturing lines. The economy leans on machinery, chemicals, vehicles and metals more than oil and gas. Ask each site for its explosion protection document to see where zones exist.

How does mountain weather affect Ex handheld devices in Switzerland?

Alpine sites can be very cold, with snow and large temperature swings, which reduces battery capacity and affects touchscreen use with gloves. Check the lowest rated ambient temperature on the certificate and the water ingress rating, and carry spare batteries in warm storage.

Which languages does the handset support for Swiss users?

Android 16 carries German and the other working languages used in Switzerland, according to the sheet. Confirm the specific language packs and keyboard layouts you need during an evaluation, particularly for crews who work across language regions.
