Littelfuse PCB Reed Switch 0.5 A 200 V MDCG-4-17-23

Littelfuse MDCG-4-17-23 PCB Reed Switch is a subminiature axial lead reed switch designed for low-power electrical switching applications with a maximum switching current of 0.5 A and voltage capacity of 200 V. This hermetically sealed device features magnetically operated contacts housed in a glass envelope measuring 15.24 mm by 2.28 mm, ensuring durability and resistance to contamination over extended operating periods.

The switch is constructed with nickel iron alloy contact material that delivers reliable performance with a contact resistance of 100 milliohms and operates efficiently up to 10 Watts of switching power. It features a fast release time of 0.2 milliseconds and an operating time including bounce of 0.6 milliseconds, enabling rapid switching suitable for industrial and electronic controls.

The operating temperature range spans from -40°C to +125°C, allowing the switch to function reliably in harsh environments. Its sensitivity AT range of 17 to 23 provides precise actuation for various applications including reed relays, security devices, limit switches, level sensing, and office or industrial equipment controls. The wire terminal and PCB mount type facilitate easy assembly and integration into printed circuit boards.

This Littelfuse reed switch meets UL and ATEX Class I Zone 2 standards, ensuring safety and regulatory compliance in intended use cases. Subminiature normally open Reed Switch with axial leads for PCB mounting. Max switching current 0.5 Amps and power 10 Watts at 200 Volts DC.
