2 Wire Sensor in Magnetic Contactor:

This diagram shows how to connect 2 Wire Sensor in Magnetic Contactor. In this circuit diagram, we simply connect a magnetic contactor with a 2-wire NC and NO sensor and DP MCB. First of all, we just input line supply to DP MCB and then output line from DP MCB to contactor and 2 wire NO and NC sensor. If you want to know more information about this circuit diagram please check our youtube video below.

Components used to make the 2 Wire Sensor in Contactor:

01. Magnetic Contactor

Magnetic Contactor
Fig 2: Magnetic Contactor
A magnetic contactor is an electrical device used for load control, automation, and protection. It is much like a magnetic reel. However, relays are generally used for low power and voltage, on the other hand, when we think of high power, these heavy-duty contractors only come to mind. It basically works by switching the load on and off. It has 3 terminals whose inputs are denoted as L1, L2, L3, and outputs as T1, T2, and T3. The circuit of the load is made in automation mode or protection using auxiliary contacts. It has two types of terminals. 1) Normally Open (NO). 2) Normally Closed (NC).

02. NPN Sensor

NPN Sensor
Fig 3: NPN Sensor
The NPN Output of the Sensor is a Switch Ground. NPN Proximity Sensors Provide an Active Low Output. This Means That When an Object Enters The Detecting Range Of The Sensor, The Output of The Sensor is Connected To The Ground. This type of Sensor Is Also Known As a 'Sinking' Sensor. In general, an NPN output can be connected directly to a digital pin, with the internal pull-up enabled. This Output Connects to GND When Active and is Floating when not Active.

03. DP MCB

Fig 4: DP MCB
Double pole MCB can control two wires. This circuit breaker is generally used in single-phase electric lines. Double pole MCB circuit breaker input has two wires supply two wires and an output. In a single-phase line, A double-pole MCB circuit breaker is used to give good production. This circuit breaker is provided through phase and neutral circuit breaker, it is very safe. This circuit breaker is preferred for home appliances. A DP MCB usually trips for 2 reasons 1. Overload 2. Short circuit.
