Inductive Ring Sensors 
Unlocking New Possibilities

Main Features

Separable housing
Cable outlet in hose direction
Flexible soft binder on the sensor
Switching status indicator visible all the way around

The in­duc­ti­ve ring sen­sors enable pre­ci­se and re­lia­ble de­tec­tion of small metal parts in feed hoses. The co­rrec­tion fac­tor 1 en­su­res re­lia­ble de­tec­tion of all metal ob­jects from a size of 2 mm. Thanks to the ro­bust soft bin­der, the sen­sor can be fixed se­cu­rely even in cha­llen­ging en­vi­ron­ments with vi­bra­tions or com­pres­sed air.

Se­pa­ra­ble Hou­sing

  • Quick and fle­xi­ble ins­ta­lla­tion and re­mo­val of the sen­sor on the hose
  • Mi­ni­mi­ze ma­chi­ne down­ti­me when re­pla­cing hoses and du­ring re­pairs
  • De­tec­tion of metal ob­jects anywhe­re in the ac­ti­ve field
  • Coil is di­vi­ded into two parts

Cable Outlet in Hose Di­rec­tion

  • Cable is rou­ted pa­ra­llel to the hose
  • Sen­sor is par­ti­cu­larly sui­ta­ble for con­fi­ned spa­ces
  • No obs­truc­tion of the sys­tem de­sign due to the cable rou­ting of the sen­sor
  • No kinks in the cable

Fle­xi­ble Soft Bin­der on the Sen­sor

  • Easy and se­cu­re moun­ting on dif­fe­rent hose sizes
  • Sta­ble fi­xing in vi­bra­ting en­vi­ron­ments, such as vi­bra­ting spi­ral con­ve­yors or com­pres­sed air con­ve­yors
  • Can be used mul­ti­ple times, as non-​destructive ope­ning is pos­si­ble, ad­di­tio­nal loss pro­tec­tion
  • No ta­pe­ring of the hose pos­si­ble

Swit­ching Sta­tus In­di­ca­tor Vi­si­ble All the Way Around

  • Com­ple­tely vi­si­ble LED dis­play
  • Swit­ching ope­ra­tion can be de­tec­ted re­gard­less of the ins­ta­lla­tion po­si­tion
  • Color dis­play:
    • Blue: power supply in­di­ca­tor
    • Ye­llow: swit­ching ope­ra­tion
    • Red: error

Other Advantages of Inductive Ring Sensors

Correction Factor 1

Thanks to the correction factor 1, inductive ring sensors reliably detect objects made of different non-ferrous metals from a size of 2 mm.

Functional Principle Static

Static ring sensors detect rapidly moving objects or objects that remain constantly inside the ring, e.g. for bottleneck monitoring.

Functional Principle Dynamic

Dynamic ring sensors are used to detect the smallest, fast moving objects, such as ejection control of rivets.

Applications with Limited Space Availability

Thanks to the compact format and integrated weproTec technology, several sensors can be installed directly next to each other in the tightest of spaces without interfering with each other.

Plug and Play

Inductive ring sensors can be easily installed via Plug & Play and quickly put into operation without prior adjustment.

Easy-to-Use Controls

Thanks to the potentiometer and IO-Link interface, inductive ring sensors offer flexible operating options for reliably reading out and processing parameters and process data.

Sectors and Industries which Use Ring Sensors

From reliable presence and bottleneck monitoring of small parts in feed tubes, to precise size differentiation and wire breakage detection, inductive ring sensors offer solutions for a wide range of applications.

Au­to­mo­ti­ve In­dustry

In the au­to­mo­ti­ve in­dustry, ro­bots com­bi­ne alu­mi­num body parts with ri­vets. In au­to­ma­ted punch-​riveting pro­ces­ses, alu­mi­num or brass ob­jects are trans­por­ted to the pun­ching de­vi­ce th­rough plas­tic hoses by com­pres­sed air. The co­rrect hose rou­ting is chec­ked be­fo­re the ri­vets are au­to­ma­ti­cally moun­ted. For this pur­po­se, an in­duc­ti­ve ring sen­sor with ad­jus­ta­ble sen­si­ti­vity and co­rrec­tion fac­tor 1 is moun­ted on the hose with a clamp. This en­su­res re­lia­ble de­tec­tion of ob­jects of dif­fe­rent sizes and alloys.

As­sembly and Fee­ding Tech­no­logy

In as­sembly and fee­ding tech­no­logy, fas­te­ners such as screws, nuts and ri­vets are au­to­ma­ti­cally con­ve­yed, sor­ted and se­pa­ra­ted by fee­ding sys­tems. These are sup­plied to the screw sys­tem via feed hoses by com­pres­sed air. In­duc­ti­ve ring sen­sors moun­ted on the hose de­tect metal parts as small as 2 mm at high speed. The se­pa­ra­ble hou­sing enables easy as­sembly and di­sas­sembly. The pre­sen­ce of the parts is vi­sua­li­zed by all-​round ligh­ting.
