Littelfuse PCB Reed Switch Subminiature Axial Lead 500 mA 200 V MDSR-10-10-15

Littelfuse MDSR-10-10-15 PCB Reed Switch is a subminiature axial lead reed switch designed for reliable low-power switching applications. This switch can handle a maximum switching current of 500 mA and a maximum switching voltage of 200 V, with a switching power rating of 10 watts.

The switch features hermetically sealed contacts of nickel iron alloy with a low contact resistance of 120 milliohms, providing high performance and durability. Form A (SPST normally open) contact design ensures the switch closes only when actuated by a magnetic field, requiring zero operating power to maintain contact.

The compact glass envelope measures 10.16 mm in length and 1.8 mm in width, making it suitable for printed circuit board mounting with wire terminals. Its operating temperature range (-40°C to 105°C) supports industrial environments with wide temperature variations.

Key technical characteristics include a sensitivity rating of 10 to 15 AT, a maximum release time of 0.1 ms, and an operating time including bounce of 0.5 ms, enabling fast and reliable switching performance.

This reed switch is widely used in industrial automation, reed relays, security systems, limit switching, and office equipment, where compact size and dependable magnetic contact operation are necessary.

Manufactured in the Philippines, the Littelfuse MDSR series maintains strict quality standards with UR certification. Its hermetic sealing offers excellent resilience to contamination, enabling long-term operation in harsh conditions.
