These new relays offer a compelling alternative to mercury-wetted relays. The environmental concerns associated with mercury-based technologies have led to a decline in their usage, prompting responsible manufacturers to discontinue offering them for new designs and seeking alternatives in existing applications. Mercury switches were once prized for their ability to produce zero bounce upon operation, a critical factor in many applications of the past. However, this feature has become less significant in today's landscape. Additionally, mercury switches generally boasted higher switching specifications compared to dry reed relays. Nevertheless, advancements in reed switch plating technologies have bridged this gap, leading to many similarly sized switches, which are used in the new Series 144 reed relays, now boasting higher ratings. Moreover, the historical inferiority of contact resistance in general reed switches compared to mercury wet switches has been addressed through advancements in reed switch plating. Consequently, the disparity between an instrumentation-grade dry reed switch and a mercury-wet switch is no longer as pronounced. As a result, numerous semiconductor testing companies that initially favoured mercury devices in their equipment designs have transitioned to instrumentation-grade dry reed relays without experiencing any loss in performance.

Have you heard about our new high power Series 144 reed relay release? With specs of 80 Watts at 1 Amp switching current or 60 Watts at 2 Amps, it's a game-changer! Compared to EMRs, these reed relays feature protected contacts in a vacuum, enabling high standoff voltage in a compact design. Plus, they're fully enclosed to shield against oxidation, ensuring reliable low-level switching and overall performance. They can also be used as a sustainable alternative to mercury wetted relays, supporting environmental protection and operational efficiency. And enjoy low on-resistance and excellent isolation between control and switching sides, unlike Solid State Relays.
