High-temperature EPC sensor HE120A (for transparent webs)

Overview Feature Configuration Specifications Product Catalog

Overview

The HE120A is a high temperature EPC sensor for use in temperatures of up to 300° C for detecting edges via the transmission method.

Feature

The sensor head is composed of a light-emitter and a light receiver between which the　measuring object passes for measurement. The HE120A outputs an analog signal (0 to 5 V DC), based on the　amount of light blocked out by the object being measured.

Configuration

The HE120 high temperature EPC sensor is composed of a light-emitter / receiver unit and a heat-resistant fiber optic cable. The light emitted from the light-emitter (LED lamp) within the light-emitter / receiver unit passes out through the heat-resistant fiber optic cable (for the light-emitter) and in through the heat-resistant fiber optic cable (for the light-receiver), which is located on the side symmetrically opposite the measured object. This light is emitted onto the light-receiver element within the light-emitter / receiver unit, converted into an electronic signal and then output as an analog signal that ranges from 0 V DC (light completely interrupted) to 5 V DC (light completely uninterrupted).
