LM18

描述

Inductive proximity switch is composed of three parts:oscillator,switch circuit and magnified output circuit The oscillator will generate an alternating electric field.When the metal object approaches this electric field and reaches the induction distance, thirlpool will generate in metal object, resulting in attenuation of vibration and then stop.the change of vibration and stop of oscillator is treated by behind stage magnified circuit and converted to switching sign,triggering driving control for non-contact detection.

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;
