Description
CR18-8AC AC 2-Wire Sensor - M18, 8mm Sensing Distance
Product Introduction
The CR18-8AC is an AC 2-wire sensor with a 100–240VAC~ power specification and Normally Closed control output. Its M18 sensing side diameter and 8 mm sensing distance provide the key mechanical and sensing parameters needed for initial model selection.
The sensor has an IP66 protection structure and operates within an ambient temperature range of -25 to 70℃ under non-freezing and non-condensing conditions. Its technical characteristics include a 20Hz average response frequency, Max. 2.2mA leakage current, and hysteresis of Max. 20% of the sensing distance.
