Pickering Electronics now offers optional electrostatic shielding for its 10kV stand-off Series 67/68 SIL/SIP reed relay families. Electrostatic screening protects against noise that can otherwise occur between the coil drive and high-voltage circuits. This new screening is in addition to Pickering’s internal mu-metal screen which eliminates magnetic interaction when devices are closely stacked. Series […]
What are MEMS relays good for?
MEMS relays (also called MEMS switches) have high isolation when open and very low insertion loss or resistance when closed; they can handle signals from DC to multi-GHz, operate with very little power, and their micrometer size means that many can be packed into a small space. These attributes make MEMS relays well-suited for 5G […]
What are the four most-common relay technologies and where are they used?
The four most-common relay technologies include electromechanical relays, reed relays, solid-state relays, and optotriacs. These relay technologies have widely varying capabilities, making them suitable for different applications. This FAQ compares each relay technology’s structures, specs, operations, and applications. The oldest and most basic type of relay are electromechanical designs. When an input value, usually current […]
When to use a relay and when to use a contactor?
Contactors are used for switching more than 15 amperes or in circuits rated more than a few kW. Except for optional auxiliary low-current contacts, contactors normally have open contacts and are used in high-power circuits. They include features to control and suppress the arc produced when interrupting heavy currents like those found in motor control […]
Where are cloud connected relays used?
Relays are humble devices, but they are not immune to being impacted by the Internet of Things. Electromechanical relays, solid-state relays, and MEMs relays are among the numerous devices in the IoT that can connect to the cloud. Some relays include Wi-Fi controllers or Bluetooth, some use power over Ethernet (PoE), and others use voice […]
Miniature reed relays boast low RF losses and low insertion loss
Pickering Electronics has launched a new miniature coaxial reed relays for high-frequency RF systems up to 3GHz. Series 113RF SIL/SIP reed relays feature a 2mm spacing footprint, enabling them to be stacked at very high densities. Series 113RF reed relays are suitable for switching up to 10W, 0.5A. 1 Form A configurations (SPST normally open) are […]
Signal relays offer max switching currents of 2 A or 3 A
CUI Devices announced the first launch from their Relays Group with the introduction of a new line of signal relays. Ideal for low-level current switching in industrial applications, security devices, and test and measurement equipment, CUI Devices’ signal relays offer max switching currents of 2 A or 3 A in SPDT (1 Form C) or DPDT (2 […]
Fail-safe hermetic SPDT relays handle up to 40 GHz signals
Teledyne Relays announces a new wide temperature range, hermetic relays operating up to 18 GHz. The new RF131 and GRF131 single-pole double-throw (SPDT) models are non-latching, offering fail-safe functionality. The new products expand rugged options available to key RF test and telecommunications markets. The RF131 and GRF131 non-latching models complement the widely respected equivalent through-hole […]
