# Kacon HLJ8A3 Induction Sensor: Unique accuracy and durability for industrial automation\r\n\r\nIn the advanced world of industrial automation, where accuracy, speed and reliability are the main priority, choosing the right equipment plays a vital role. The proximity sensors as the eyes of the production lines are responsible for detecting and counting the components with the least error. In the meantime, ** ** HLJ8A3\'s proximity sensor from the reputable KACON brand, with a combination of engineered design, compact and super -functional dimensions, is considered a smart choice for industry professionals. This sensor, with only 8 mm in diameter, is an ideal solution for limited spaces and applications require quick response.\r\n\r\n## Design for the most challenging industrial environments\r\n\r\nOne of the biggest concerns in various industries is the durability and sustainability of parts in harsh conditions. The Kacon HLJ8A3 sensor is designed to fully understand this need. The body of this sensor is made of first -rate and durable materials and with ** IP67 ** Defense, is completely sealing and sealed against water, dust and oil. This feature assures you that the sensor will perform well and stable even in humid or dusty environments.\r\n\r\nIn addition to physical resistance, the sensor is also electrically protected. Its internal circuit is equipped with ** protection against reversal polarity ** and ** for short circuit protection **. These two vital features protect the sensor from common wiring errors and prevent damage to it and other equipment connected to the control system. As a result, maintenance costs are reduced and the production line fails is minimized.\r\n\r\n## accurate and exemplary speedy performance\r\n\r\nThe beating heart of the HLJ8A3 sensor is its ability to accurately and rapidly detect metal objects. This sensor is Shielded (SHIELDED) and offers a standard diagnostic distance of 1.5 mm ** (with 10 % tolerance). The shield structure means that the electromagnetic field is concentrated on the front of the sensor and allows the surface to be installed with other metal parts without interference. This feature is a key advantage for installation in compact spaces and metal molds.\r\n\r\nBut the main distinction between the sensor is the ** work frequency above 2 kHz (2khz) **. This very fast response frequency allows the sensor to work with high speed in high speed applications such as counting small parts on the conveyor, controlling the position of the robotic arms, or detecting the presence of the piece in fast presses. The red LED marker embedded on the body also clearly displays the performance of the sensor and makes the installation, adjustment and troubleshooting process much easier for operators.\r\n\r\n## key technical specifications\r\n\r\nTo better understand the capabilities of this sensor, take a look at the technical specifications table:\r\n\r\n| Technical Features | Value | Description |\r\n| : --- | : --- | : --- |\r\n| ** Model ** | HLJ8A3-1.5-Z/N3 | Induction sensor with NPN output |\r\n| ** Sensor diameter ** | 8 mm (M8) Ideal for installation in limited spaces\r\n| ** Installation type ** | Head
