Product Description

The QS90SR2SN-EX is a rugged, explosion-proof SR2SN limit switch from the QS90 Series Sensor line, designed for hazardous environments. It features a single-channel output, supports direct integration with up to 4 control modules, and operates on 10-30V DC within a temperature range of -25°C to +70°C. Ideal for oil & gas, chemical, and heavy industries, it offers a reliable detection distance of up to 10mm using its contactless switching mechanism. The device lacks a display but ensures durability with an IP67-rated housing. Advantages include ATEX/IECEx certification, high shock resistance, and corrosion-proof construction, though it requires external power due to no onboard battery. Communication is limited to hardwired signals, prioritizing simplicity in critical applications.
