Conveyor belts are widely used in automated assembly, logistics sorting, packaging and machining workshops. This classic two-proximity-sensor control circuit relies on intermediate relays and AC contactors to realize logic control of the conveyor, which can complete functions like position limiting,…
Many maintenance technicians and automation engineers often receive unmarked inductive proximity sensors without datasheets, making it impossible to confirm whether the unit is PNP NO or NPN NC before wiring to PLCs and equipment. Incorrect matching of output types will…
Many automation engineers, maintenance technicians, and factory procurement staff face confusion when selecting proximity sensors for production lines. With various types, output modes, sizes, and installation standards on the market, improper selection is the leading cause of sensor false triggering,…
Proximity sensors are essential detection components for all automated manufacturing equipment. Unlike mechanical limit switches, they achieve non-contact object detection without physical collision, extending service life and reducing equipment failure. Based on working principles and detectable targets, there are four…
In industrial automation, analog 4-20mA signal acts as the critical bridge connecting physical field equipment and digital PLC/DCS control systems. Unlike simple on-off proximity switch digital signals, analog signals transmit continuous real-time data such as distance, temperature, pressure, flow rate…
When installing inductive proximity switches on automated production lines, confusion about PNP and NPN wiring is one of the most frequent problems for maintenance engineers. Wrong wiring leads to sensor no response, PLC signal failure, relay burnout, and unplanned production…
Factory buyers look for approved proximity sensor to guarantee stable, compliant operation on automated production lines. Uncertified cheap sensors often fail EMC tests, trigger signal errors, or fail factory equipment safety audits. Our HongSton proximity switches are fully approved with…
Strong electromagnetic interference from inverters, welding machines and high-power motors is a universal trouble for automated factories. Ordinary proximity sensors easily trigger false signals, causing unexpected line shutdowns, waste products and extra maintenance costs. That’s why many equipment factories seek…
For manufacturing factories, a full set of automated production lines requires a huge upfront investment, and equipment maintenance, component wear and regular replacement bring long-term extra expenses. To truly cut production costs and reduce losses caused by unexpected shutdowns, blindly…
When factory managers, maintenance engineers, and procurement teams look for industrial inductive proximity sensors, they always face the same question: which is the best proximity sensor for long-term stable operation and cost-effective production? The industrial sensor market is dominated by…
Proximity switches are non-contact position sensors that output control signals once targets reach the effective sensing distance. Thanks to stable performance, strong anti-interference, waterproof and corrosion-resistant features, they are widely adopted in automated production lines. 1. Common Classification of Proximity…
1. Magnetic Switches A magnetic switch is a magnet-sensitive proximity switch, widely used to check if cylinders reach the designated position in automation systems. It is divided into contact and non-contact types. Built around a reed switch, it closes the…
