Inductance proximity sensor M18 works

  • LM18
  • Winston

This sample came from Winston Electric CO.,Ltd, it's inductance type, As you see, the model number of this one is LM18, it used to detect metal, The features of this series are compact volume and good performance of anti-interference. i will show you next. The detection distance of this type is 5mm, it can be made long or short as required, When it works, the led light is on

 Model explanation of proximity switch

 1. Switch category(LM: inductance type; CM: capactitance type;SM:Hall type; AM:safety explosion-proof type; XM: mimic linear type)
 2. Outward appearance code(C: Cylinder type; F: Angular column type and planeinstallation type)
 3. Operating voltage(30: 6-36VDC; 310: 5-24VDC; 320: 12-60VDC; 20:90-250VAC; 210: 24-250VAC;220: 380VAC; 40: 12-240VDC/24-240AC; 50: Special voltage)
 4. Detection distance( 01: 1mm; 05:5mm; 10:10mm)
 5. Output method (N: Three-line DC NPN output;P: Three-line DC PNP output;
 L: Two-line DC output; AC two-wire output;J: Relay output;NP: NPN+PNP output)
 6. Output status(A: NO; B: NC; C: NO+NC; MU: Mimic voltage; MI: Mimic current)
 7. Auxi function code(T: With connector; Y: Water proof, oil proof; I: Special requirement;
 H: High temp resistance; R: Ring type)
