Magnetically controlled sealed closing contacts of increased power (reed switches) MKS-52201 are intended for switching active and inductive electrical circuits in devices of wide use:

• in normal switching mode with currents from 1 mA to 2.5 A, voltage from 6 to 220 V DC and from 6 to 380 V AC, frequency 50 Hz, power up to 400 V A;
• in the mode of rare switching with currents up to 34, 65 A, voltages up to 660 V AC, frequency 50 Hz, power up to 3328 VA, currents up to 8.8 A and voltages up to 330 V DC, power up to 232 W.

Reed switches are used as switching elements in automation and control equipment and are suitable for operation in harsh environmental conditions (increased dustiness, aggressiveness of the environment), as well as in cases where an increased resource and reliability are required.
