Teledyne Relays has announced the availability of four new reed relay product families, all offering extremely long life of up to 1 billion cycles, ideal for applications where high reliability is essential. The new product lines complement the already broad array of rugged switching solutions the company has been supplying for more than 60 years.

Reed relays offer a compact and lightweight solution for switching of AC or DC signals. Contacts are hermetically sealed inside a glass envelope which protects them from corrosion. Compared with other mechanical-based relays, reed relays offer low power consumption, low contact capacitance and faster switching speeds.

The new reed relay product families are optimized for different customer demands:

• Single-in-line (SIL) and Dual-in-line (DIL) packaged parts containing one or more reed switches and an electromagnet, encapsulated in thermoset plastic and packaged for easy solderability to a printed circuit board, or inserted into sockets for easy replacement.
• The new HVR series relays are designed for high voltage/high power applications and can switch up to 7.5 kV, 1.5 kW.
• For applications where isolation is a priority, the HIR series offers up to 3 kV isolation between coil and contacts.
• MCR series relays are designed with a focus on metal shielding. Options include shielding to protect contacts from external interference from other nearby relays and components, or to isolate contacts from electrostatic interference coming from the coil circuit.

Michael Palakian, Teledyne Relays’ Global Director of Sales & Marketing said that Teledyne’s new products provide some of the fastest switching times, highest vibration resistance and widest operating temperature ranges available.

Applications for the new products include radar, telecommunications, automated test equipment, dielectric voltage testing/ Hi-Pot testing, ESD sensitivity testing, and power protection circuits.

Devices are available for ordering and shipment from Teledyne Relays or an authorized distributor.
