Advanced M40 Inductive Proximity Sensor for PNP/NPN Applications

Product Description

Introduction

Inductive proximity switch is a device for realizing the non-electrical measurement by inductive winding or the change of coefficient of mutual induction.

• It has high resolution and accuracy for the monitoring and measurement of presence, movement and position of metallic objects.
• The operating distance of the sensor depends on the coil's size as well as the target's shape, size and material.
• It is divided into two categories according to the working state : 

    NO - Normal Open type, 
    NC - Normal Close type

Feature

1. Equivalent to the same type of the other brands  (P+F and TURCK).
2. Power supply reversal connection protection; short-circuit protection, can directly connect with PLC
3. Newly added current over-load protection; the elements are made of imported chip
4. Long service life, high reliability and strong resistance property to environment
5. Red LED indicates that it's available to detect the sensor operating state
6. Full thread shape to enlarge the installation space; can use wrench and clamp directly
7. Countermeasure to improve the housing intensity and to solve disconnection

IP65 protection structure(IEC specification)
