Product Specification
| Description | Linear, Compass (ICs) RoHS | Mfr. Part # | DRS-50-77-88 |
| Model Number | DRS-50-77-88 |
The Littelfuse DRS-50 is a standard, normally open (Form A, SPST-NO) high-power reed switch designed for demanding applications. It features a hermetically sealed glass envelope, ensuring reliable operation unaffected by its environment. Capable of switching high voltages and power up to 400Vdc at 2mA, with a carry current of 6A and a maximum switching power of 100W/VA. This switch offers high insulation resistance (1010 ohms minimum) and low contact resistance (less than 100 milliohms). Ideal for security systems, limit switching, industrial applications, and white goods.
