Not yet rated Write a review


CR Series features electric capacitive type proximity sensors. These sensors will detect a wide variety of materials with permittivity and can not only detect conductive materials such as iron and metal but also nonconductive materials such as plastic, water, stone and wood. Moreover, built-in sensitivity volume allows users to apply in a diverse area for user convenience.

Main Features

● Long life cycle and high reliability
● DC type: Built-in surge protection circuit, reverse polarity protection circuit AC type: Built-in surge protection circuit
● Easy to adjust of the sensing distance with sensitivity adjuster
● Red LED operation indicator
● Easy to control of level and position

† 1: The response frequency is the average value. The standard sensing target is used and the width is set as 2 times of the standard sensing target, 1/2 of the sensing distance for the distance.
† 2: The weight with packaging and the weight in parentheses is only unit weight.
† Environment resistance is rated at no freezing or condensation.
