THÔNG SỐ KỸ THUẬT

Sensors for potentially explosive areas

Detect without risk

The use of optoelectronic sensors in potentially explosive areas requires specially protected devices. Our extensive product line offers powerful sensors in all common technologies.

92 series

Productselector

Intrinsically safe sensors for zones 1 and 21 with NAMUR

The sensors of the 92 Ex series are designed as diffuse reflection light scanners, retro-reflective photoelectric sensors or throughbeam photoelectric sensors and reliably detect objects at distances between 300 mm and 12 m. The intrinsically safe sensors transmit switching signals to the VS 403 isolated switching amplifier by way of the NAMUR interface. The temperature class for explosive gas areas is T6; for explosive dust areas it is 80°C.

55 series

Productselector

Compact sensors for zones 2 and 22 in stainless steel

The sensors are developed for all category 3G and 3D applications. With their small dimensions, they fit even in constrained spaces. The sensors and the protective housing are made of stainless steel and are also suitable for demanding operating conditions. Currently available are retro-reflective photoelectric sensors and scanners with background suppression. The temperature class for explosive gas areas is T4; for explosive dust areas it is 70°C.

46 series

Productselector

Powerful sensors for zones 2 and 22

Due to their high performance reserve, these devices are used for reliable detection even with heavy soiling in category 3G and 3D applications. The product spectrum encompasses familiar operating principles such as throughbeam photoelectric sensor, retro-reflective photoelectric sensor or scanner with background suppression. The temperature class for explosive gas areas is T4; for explosive dust areas it is 90°C.

96 series

Productselector

Long-range sensors for zones 2 and 22

These sensors were specially designed for applications that require large ranges in categories 3G and 3D. The product line covers all operating principles. The temperature class for explosive gas areas is T4; for explosive dust areas it is 70°C.
