Datasheet - DBT70505FU

Sensata Cynergy3 Reed Relay, Tungsten Contacts, 2ms Operating Time - DB(UL) Series - DBT70505FU

Safely turn on the electrical circuits in your equipment using this reed relay from Sensata Cynergy3. It works by closing the internal contacts when power is applied to the electromagnetic coil, energising the circuits. The contacts are made of highly conductive tungsten to ensure reliable switching. A wide operating temperature range between -20°C and +70°C means this unit can withstand use in demanding environments. Use this relay to control sensitive switching applications in your mining, oil and gas facilities.

Features & Benefits

• Fast operating time of 2ms and release time of 3ms for rapid switching
• Maximum switching voltage of 3500V AC/DC for use in high-voltage systems

What's the difference between tungsten and rhodium contacts?

Reed relays with tungsten contacts are designed to switch on power in high-voltage devices, while reed relays with rhodium contacts have low contact resistance for use in lower-voltage devices.

How long will this reed relay last?

This reed relay has a long electrical life of one million 50W switching cycles and one billion dry switching cycles, so you can rest assured it will last a long time.
