The PRCM18-8AO operates with a sensing distance of 8mm and is optimized for detecting 25Γ25Γ1mm iron targets. It features a non-flush M18 housing and runs on AC 2-wire 100β240VAC~ power, making it ideal for systems that use AC input directly. The sensor includes a Normally Open output with a maximum leakage current of 2.5mA and residual voltage up to 10V, supporting consistent signal transfer in factory environments. It is built with nickel-plated brass and provides IP67-rated protection, shielding it against oil, dust, and moisture. Operating across a temperature range of -25Β°C to 70Β°C and humidity levels up to 95% RH, this sensor delivers dependable detection in variable Indian conditions. A response frequency of 20Hz suits applications that require steady but not high-speed sensing. The sensor also incorporates double or reinforced insulation with 1kV dielectric strength, meeting industrial safety standards for AC systems.
Engineers typically install the Autonics PRCM18-8AO in packaging lines, rotating machinery, mechanical gates, and component detection units that operate on AC power. Its ability to function without requiring external converters or power supplies simplifies wiring, especially for retrofit panels and legacy machines. Junior maintenance staff find the connector design easy to handle, while senior engineers value its stable operation even in fluctuating voltage environments. Whether youβre managing OEM automation or upgrading plant-level sensing infrastructure, this model offers proven durability, simple wiring, and accurate performance.
