Overview
The Q45AD9 Series NAMUR Sensor is a rugged, self-contained two-wire sensor designed for use with certified intrinsically safe switching amplifiers and barriers (Approved Apparatus) with intrinsically safe circuits.
The Q45AD9 Series NAMUR sensor is designed in accordance with DIN 19234 (IEC/EN 60947-5-6) for operation via two-wire connection to an Approved Apparatus controlled by the variable internal resistance of the sensor.

No revision without agency approval.
