Automatic Continuity Test Machine (CT) Using Proximity Sensors, Photoelectric Sensors and Programmable Logic Controllers (PLC) Systems: The case at PT. “V” Batam Indonesia

Continuity test Machine (CT) is a tool for detecting damage to the current connection on AC plug cable. The problem with PT “V” that it still uses manual system. So updated an automatic continuity machine by measurement using "caliper" and another (CT). results obtained proximity sensor, photoelectric as detector length of pin connector Programmable Logic Control (PLC) system controller. Testing accuracy 12 samples were same, namely 10 standard (19.05 +_0.2 mm) 2 not standard. Tool performance testing carried out operating 184 hours or 23 working days. data analysis found significant increase, average 25.94% total used Totally capable increasing 970 product units per month, details reducing -20.03% good products, 26.74% products (standard)
