PS-482/484/488 Slug Detector


The sensor cable Proximity Sensor head Order codes Leaflet


The Slug Detectors PS-482/484/488 are designed for detecting slugs, double piles driving, and so on, during automatic press working and for outputting stop signal to the press in case of abnormalities.
It reads a signal from Eddy current proximity sensor installed on the mold for the press and calculate the displacement by a microcomputer. If the displacement exceeds the limit, it outputs the stop signal to the press.
Since Ethernet is supported, the PS-482/484/488 can be connected to personal computer (PC) and PLC.


The PS-482/484/488 have the following additional features together with those of our PS-462/464.
 Added functions helpful for detection
  • - The LCD panel displays sensor waveforms.
  • - Sensors can be connected up to eight (8) channels.(PS-488)
  • - Unevenness calculation and multiple detection are available.
 Functions helpful for production control
  • - Up to 99 patterns can be Stored.
  • - Up to 1000 error histories and displacement for four strokes before and after the error can be saved.
  • - Patterns can be recalled by ID tags. (Options)
 Ethernet supported
  • - The contents of setting can be displayed in HTML format.
  • - UDP protocol and Telnet protocol enable various settings and operations.
  • - FTP protocol enables to output the displacement data during press working.
