HW-5052 Reed Switch for High Wattages
This HW-5052 High Wattage Reed Switch is physically robust and can switch up to 120W. The two types of contact ratings available cover a wide range of high wattage applications. When supplied in a release AT group and used Normally Closed with a biased magnet, it is especially useful in elevator and hoist applications. Close differential characteristics can also be built into this high wattage reed switch. In addition to the standard Normally Open configuration, we can also supply this reed switch in a normally-closed or a latching form. This reed switch is completely Lead-free and conforms to the RoHS directive. The cropped version is suitable for smaller plastic housings and can be soldered to cables.
Features
Contact Rating Configurable. Ruthenium contact. 50.0 mm Glass length. Normally Open. Inert gas filled. Cropped Version available.
Benefits
Omni-polar. Does not require power for operation. Sputtered Contact. RoHS Compliant. Not ESD Sensitive.
