Musktool-PK-1990H - High-Speed Long-Range Photoelectric Sensor - Industrial Automation Rugged Metal Detection Module
Product descriptions from the supplier
1. Product Overview: Precision Pressure Monitoring
| The KEYENCE PK-1990H is a high-performance industrial pressure switch designed for critical automation environments. Part of KEYENCE’s renowned PK series, it integrates sensing, display, and control functions into a single compact unit (housing dimensions: 35 × 18 × 65 mm). Engineered for reliability in harsh conditions, it features an IP67-rated stainless steel casing resistant to water, oil, and dust ingress. The device combines a pressure transducer, digital display, and switching circuitry to monitor hydraulic/pneumatic systems with exceptional accuracy. Its LED indicator provides real-time status feedback (green/red for OK/alarm), while the ergonomic push-button interface simplifies setup without external tools. Ideal for robotics, assembly lines, and process control, the PK-1990H ensures seamless integration into PLC/DCS networks. |
2. Key Technical Parameters & Specifications
| The PK-1990H delivers precision with a measuring range of -100 kPa to +1 MPa (customizable scales) and ±1% FS (Full Scale) accuracy. Its response time of ≤1 ms captures rapid pressure fluctuations, critical for high-speed manufacturing. The unit operates on 12–24 VDC power and offers NPN/PNP transistor outputs (dual switch points configurable) with 100 mA max load capacity. Environmentally robust, it withstands temperatures from -10°C to +60°C and shocks up to 100 m/s². The sensor’s brass or stainless steel diaphragm (optional) ensures compatibility with aggressive media like coolants or compressed air. Additional features include zero-point calibration, auto-shutdown for overload protection, and CE/UL compliance. |
