Littelfuse PCB Reed Switch 250 mA 175 V MDRR-DT-25-30-F

Littelfuse MDRR-DT-25-30-F PCB Reed Switch is a miniature, subminiature axial lead reed switch designed for low power switching applications. It supports a maximum switching current of 250 mA and voltage of 175 V, delivering up to 5 W of switching power. Its hermetically sealed glass envelope (dimensions approximately 15.24 x 2.28 mm) provides superior protection and long operational life even in contaminated environments.

The device features Form C (SPDT changeover) contacts with a nickel iron alloy contact material, resulting in a contact resistance of just 100 mΩ. Its magnetically operated switch design ensures reliable closure without the need for external power.

Operating within a temperature range from -40°C to +125°C, this reed switch is suitable for harsh industrial and commercial uses such as position sensing, reed relays, industrial controls, office equipment, home appliances, and security systems.

The MDRR-DT series includes several sensitivity options. This specific MDRR-DT-25-30-F model offers an AT sensitivity rating between 25 to 30 AT, delivering precise actuation.

Mounting is designed for PCB use, with wire terminals facilitating integration into printed circuit boards. With fast switching cycles, including a maximum release time of 1 ms and operating bounce time of 0.7 ms, it supports responsive electrical applications.
