Historically, one can rightly claim that explosion protection measures had their origins in mining. 200 years ago, the first more or less effective approaches to occupational health and safety in mining were undertaken with the ignition lamp or with the help of canaries. Today, security is a determining topic and we deal with topics such as – Autonomous Mining or create international communication standards for data exchange between devices with the OPC UA.

Despite the internationalization of the standards, approvals for mining equipment are usually subject to special national controls and supervision.

DGMS (India), MA (China), MSHA (North America), ANZEx (Australia) to name just a few.

PROPORTIONAL SOLENOID WITH MINING APPROVAL
M2 Ex eb mb

Robust powerful proportional magnet in square explosion-proof design.

IECEx and ATEX approval.

HALL SENSOR WITH MINING APPROVAL 
M1 Ex ia
