2. Key Selling PointsSuitable for Both Liquid and Gas Media – Wide Application Range:The TN7531 can monitor pressure or status in both liquid and gas systems, offering excellent versatility for use in pneumatic, hydraulic,
cooling, and industrial process applications. M18 × 1.5 Internal Thread Connection – Standardized and Reliable
Installation:Features an M18 × 1.5 metric internal thread interface, compliant with ISO standards, ensuring secure sealing
and easy integration into common pressure lines—ideal for
low-to-medium pressure systems. Wide Operating Voltage (18...32 V DC) – High Compatibility:Operates on 18–32 V DC, fully compatible with standard 24 V industrial control systems.
Tolerant to voltage fluctuations, ensuring stable performance in
demanding electrical environments. Dual Output (2 Outputs) – Enhanced Functional Flexibility:Equipped with two independent output channels, enabling simultaneous functions such as pressure monitoring and alarm signaling, high/low limit detection,
or status feedback, ideal for advanced control strategies. Switchable PNP/NPN Output – Adaptable to Various Control Systems:Output type can be switched between PNP and NPN modes, allowing direct connection to different PLC brands (e.g.,
Siemens, Omron, Mitsubishi), eliminating the need for external
interface modules and simplifying integration.
