DRT-DTH Series - 39.7mm High Voltage Changeover Reed Switch

DataSheet:Littelfuse Reed Switches DRT-DTH datasheet

A standard changeover switch with a 39.67mm long x 5.33mm diameter (1.562" x 0.210") glass envelope, with tungsten contacts capable of high voltage and power switching up to 500Vdc at 50W. Minimum breakdown voltage of 1000Vdc. Available sensitivity range of 50-80 AT. Insulation resistance of 1 Gigaohm minimum and contact resistance less than 500 milliohms. Ideally suited for security, limit sensing, industrial, white goods and automotive applications.

Features:

Changeover switch capable of switching 500Vdc or 1.5A at up to 50 Watts
Minimum breakdown voltage of 1000Vdc
Available sensitivity range of 50-80 AT

Benefits:

Hermetically sealed switch contacts are not affected by and have no effect on their external environment
Can be used as changeover or normally closed contact
Capable of switching global mains voltage
Zero operating power required for contact closure

Applications:

Security
Limit switching
Industrial safety
White goods
