PR Series enhance superior noise resistance characteristics with dedicated IC which Autonics self-developed. Also, the series can be widely used in any applications where proximity sensors are required because of diverse range of line-ups in terms of size and sensing distance.

Main Features

● Improved the noise resistance with dedicated IC
● Built-in reverse polarity protection circuit(DC 3-wire type)
● Built-in surge protection circuit
● Built-in overcurrent protection circuit(DC type)
● Long life cycle and high reliability, and simple operation
● Protection structure IP67(IEC standard)
● Replaceable for micro switches and limit switches

† 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: Before using non-polarity type, check the condition of connected divice because residual voltage is 5V.
† 3: The weight with packaging and the weight in parentheses is only unit weight.
† Environment resistance is rated at no freezing or condensation.
