Digital Fiber-Optic Sensors Easy operation and high performance for a variety of applications HPX-AG Series Dual display shows incoming light level and preset value side by side. High sensitivity and ultra long distance (1,200mm with the standard HPF-T003 thru scan fiber in high power mode) Three types of auto-tuning: 2-point, BGS and % EXPLANATION OF MAJOR FUNCTIONS AND FEATURES Easy-to-use design Auto-tuning button Function selection button Dual display panel Preset value Incoming light level The digital dual display panel indicates incoming light level and preset value side by side, so it is easy to check current scanning status while setting the sensor. The button layout is especially designed to ensure easy operation of gang-mounted sensors. Output indicator ＋Button －Button Easy operation Digital manual tuning With controls that are as easy to operate as a conventional potentiometer, and with easy-to-read digital display, settings can be changed directly in RUN mode. Less wiring, fewer man-hours The new models offer a choice between cable lead-out, M8 connector for fast installation, and reduced wiring models that receive power directly from adjacent gang-mounted units. Up to 16 units can be gang-mounted, with only the main unit wired to the power supply. M8 connector type Reduced wiring type Units are designed so that connecting cable is not required. There are no worries about wiring mishaps when mounting or dismounting. NEW Wiring with an M8 connector cable Add 1 sensor— save 2 wires! Up to 16 units can be combined. Since power is supplied through the gang-mounting connectors, only an output wire is required for the expansion units. NEW Long and short Four-element LED make light and APC emission level twice as stable. term stabilization Four-element LEDs shine brightly longer than conventional Stability when power is first LEDs. Furthermore, Auto Power supplied is also improved. Control (APC, light emission level control) monitors the level of light emitted by the LED, and regulates the current to maintain light emission at a Without APC circuit Note: APC controls the light emission level of the LED emitter, constant level. Light emission level but does not compensate for a drop in received light level due to other factors. Time 1 Advanced scanning performance for expanded possibilities High sensitivity and ultra long distance Five selectable sensing modes High-level performance is achieved with the built-in APC. Five sensing modes are selectable by desired response speed and sensitivity, according to what is best for your application. High sensitivity Sensing mode Response speed Maximum Sensing type: HP3 (Response time: 5ms) HP (high power) 5ms 2,230mm nL (normal) 1ms HPF-T001 Thru scan fiber unit SF (semi-fast) 500μs FT (fast) 250μs HS (high speed) 50μs High speed Long distance and high sensitivity modes: Setting in 1-digit increments is possible. High accuracy detection Countermeasures for short-distance saturation Sensitivity adjustment Note: Under optimum conditions New countermeasures have been added since the sales up to 1/100 release of the HPX Series. Even for small difference detection at short distances or for a high reflection ratio on both target object and background, HPX sensors deliver reliable detection performance.

NEW Remote tuning –Seamless remote tuning– Long-term reliability BGS or % tuning can be done remotely from a connected device. Seamless remote tuning is carried out based on the sensing situation. For the sensing type selected in advance, Flexibility for tooling changes this function selects one of 3 types of sensitivity and the appropriate setting value. Even when the light level is dropping due to a change in tooling, application environment, or installation conditions, stable and highly accurate detection can be assured by periodic re-tuning. After remote tuning, set value is changed. ON Environment has worsened due to paper powder. For remote full auto-tuning, use the HPX-AG03 series.
