Description
Omron F03-20T 2-pole sensor terminator features a 10 VDC maximum detection signal, 1 W maximum power consumption, and supports up to 400 m maximum wiring distance. Engineered for integration with liquid leakage sensor amplifiers, this component utilizes an inter-electrode resistance detection method to ensure stable operation. The terminator is constructed to facilitate disconnection detection by maintaining a closed loop at the end of a sensing band, allowing the main amplifier to monitor circuit integrity. It operates in conjunction with 3-conductor VCT cables and features a compact form factor designed for panel space optimization.
