di-soric Inductive Ring Sensors IRSD series
di-soricIRSD / IRB / IS / IRDBIO-Link

Inductive Ring Sensors

di-soric inductive ring sensors detect the smallest metallic parts conveyed in supply tubes. The product family covers four series: the IRSD with IO-Link for flexible integration; the IRB Standard for simple plug-and-play applications; the IS and ISDP tube sensors for flexible clamp-on assembly on pipes and tubes; and the IRDB / IRDBD wire-break sensors for detecting breaks in the finest wires. All devices are protected against overload, short-circuit, and polarity reversal. The IRSD series offers 16 variants in 8 sizes with bore diameters from 6 mm to 50 mm, all IO-Link capable and available with or without potentiometer.

Key Features — IRSD Series

  • High resolution for detecting low-mass or very small metallic objects with process reliability.
  • Static or dynamic operating principle selectable; NO/NC switchable; push-pull / pnp / npn in one device.
  • Pulse stretching adjustable via IO-Link — generates analyzable output signals for rapidly passing parts.
  • IO-Link diagnostic function Stability: warns when object detection is impaired by soiling; auto-resets after cleaning.
  • Working frequency switching via IO-Link — prevents mutual interference when multiple sensors are mounted adjacent to each other.
  • Autoteach / Intelliteach: automatic teach-in of objects with intelligent suppression of environmental conditions.
  • Remote Teach via IO-Link or digital pin 2; extended diagnostics for process monitoring.
  • Robust housing rated IP67; M12 connection technology; compact design for tight installation spaces.

Applications

  • Supply of springs and small stampings in automated assembly — process-reliable detection of low-mass objects fixed on the tube.
  • Format-flexible screw and fastener feeding at manual workstations — sensors reconfigured via IO-Link without manual adjustment risk.
  • Multi-point assembly with multiple sensors installed side-by-side — different working frequencies prevent cross-interference.
  • Robotic and handling systems requiring sensors that withstand rapid motion without slipping — IRSD robust housing and IO-Link remote configuration.
  • Wire production lines — IRDB series detects wire breaks and end-of-wire conditions to reduce rejects in automated wire processing.
  • Tube-mounted counting and accumulation monitoring on conveyor tubes using IS / ISDP series (cable-tie assembly, no disassembly needed).
  • Electronics industry component feeding — IRB Standard for simple, manipulation-proof integration without potentiometers.
