## Description

The Sensata / Cynergy3 S2-03P is a single-pole single-throw normally open (SPST-NO) reed relay housed in the compact S2 Series through-hole package. Designed for applications requiring reliable low-level signal switching with galvanic isolation, this component features a coil rated at 3 VDC with an internal coil resistance of 250 ohms, drawing a nominal operating current aligned with standard low-voltage microcontroller logic outputs. 

Engineered for precision instrumentation, automated test equipment (ATE), and telecommunications interfaces, the S2-03P handles a maximum switching current of 250 mA and can withstand switching voltages up to 200 VDC/VAC. The hermetically sealed reed switch contacts ensure low and stable contact resistance over extended operating lifetimes by preventing atmospheric contamination of the contact interface. The through-hole mounting configuration facilitates secure PCB retention and thermal stability in dense electronic assemblies requiring robust electro-mechanical signal routing.
