3-pole socket connection

3-pole socket connection:

This diagram shows how to make a 3-pole socket connection. In this circuit, we use a 3-pin socket, an emergency switch, and a wire sensor. First, we need to connect the sockets with a power source, then connect the wire sensor, then connect the emergency switch.

Components used to make the 3 Phase Socket wiring:

01. Wire 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

02. 3 Pin Socket

A socket is a type of equipment used in electrical wiring lines that always has an electrical connection. According to the need, it can be supplied to the electrical equipment. In case of electric iron, electric hand drill machine and electric hand grinder etc. two-pin socket with earth terminal is used. Also, three-pin sockets are used for electrical appliances that have a metal body and are likely to be electrified. Eg – Refrigerator, room heater, table heater, hot-plate, electric oven etc.

03. Emergence Switch

An Emergency Stop Switch is a Safety Mechanism Used to Shut off Machinery in an Emergency When it Cannot be Shut Down in The Usual Manner. The Purpose of an Emergency Push Button is to Stop The Machinery Quickly When There is a Risk of injury or The Workflow Requires Stopping. Machinery And Equipment Used in Factories and Other Facilities are Equipped With an Emergency Stop Function to Stop The Machinery And Equipment in an Emergency to Ensuring Operator Safety as Complementary protective measures.
