TX2SA-5V Panasonic TX Signal Relay – 2 Form C, 2 A, 5 V DC, Surface Mount
The Panasonic TX2SA-5V (Panasonic part number ATX209SA) is a sealed signal relay from the TX series, in the SA-type surface-mount version with a 5 V DC coil. It has two changeover contacts (2 Form C) with gold-clad silver alloy contacts. These switch reliably from low-level signals down to 10 µA / 10 mV DC up to 2 A at 30 V DC. The TX series stands out for its insulation: 2,000 Vrms between contacts and coil and 2,500 V surge withstand, which makes it a long-standing choice for telecom, measurement, security and industrial control boards. The 5 V coil draws only 140 mW, so it can be driven directly from logic-level circuits.
