Datasheet DAT72405U

Sensata Cynergy3 PCB Mount Reed Relay, 50W Switching Power, 5kV Contact Isolation - DA(UL) Series - DAT72405U

This reed relay from Sensata Cynergy3 is designed to switch power to electrical circuits in a device. Its two contacts are made from a highly conductive tungsten material, making it suitable for use in high-voltage systems. The PCB pin terminals mean it's quick and easy to install on a circuit board. Thanks to its broad operating temperature range between -20°C and +70°C, it's suitable for use in harsh industrial environments. This relay is ideal for use in sensitive applications that need reliable switching, like medical devices and test equipment.

Features & Benefits

• Long service life of one billion dry operations for long-term performance
• Compact dimensions of 60 (length) x 15.8 (width) x 18.5mm (height) to maximise space on a PCB

How does this reed relay work?

When power is applied to the reed relay, its electromagnetic coil sends magnetic energy to the contacts, closing them and activating the electrical circuit.

How quickly does this relay respond?

This reed relay has a fast operating time of just 3ms, helping to ensure rapid switching.
