Not yet rated Write a review


BEN Series is built-in amplifier type in a compact size. This type has an indicator to allow users to identify operation status of sensors from a long distance.

Main Features

● Small and power supply built-in type
● Easy installation with LED indicators on product
● Enables to set the operation mode by VR (Light ON/Dark ON)
● Status and output LED indication
● Built-in IC photo diode for ambient light and electrical noise 


* Sensing for position, presence and absence of bottles in production lines

† 1: The sensing distance is specified with using the MS-2 reflector and same as the MS-4 reflector. Sensing distance is setting range of the reflector. The sensor can detect under 0.1m.
† 2: It is for Non-glossy white paper(100×100mm)
† The temperature or humidity mentioned in Environment indicates a non freezing or condensation environment.
