Teledyne Relays Series 114 Established Reliability Relays DPDT

Category: Electronics, Relays, Teledyne Technologies Incorporated

Overview

The Teledyne Relays Series 114 Centigrid^® datasheet details ultraminiature, hermetically sealed, armature relays. The document introduces the DPDT (Double Pole Double Throw) basic relay and its variations, the 114D and 114DD, which incorporate internal diodes for coil transient suppression and polarity reversal protection.

Internal Construction and Design

The Series 114 features a low profile height of 0.275 inches and 0.100-inch grid-spaced terminals, allowing for a high-density packaging and narrow PC board spacings. These DPDT relays parallel the internal construction of standard Teledyne DPDT TO-5 relays, such as the Series 412, but with additional construction features and manufacturing techniques aimed at delivering enhanced reliability and environmental resistance.

A unique uni-frame design is referenced, which ensures high magnetic efficiency and mechanical rigidity. High force-to-mass ratios in the construction make these relays tolerant to shocks and vibrations. The use of all-welded construction and advanced cleaning methods provides a guarantee of cleanliness internally. The moving and stationary contacts are made from a precious metal alloy with gold plating, ensuring high-quality switching capabilities in both high current and dry circuit conditions.

Environmental and Physical Specifications

The relays can operate within a temperature range of -65°C to +125°C. Resistance to environmental conditions is also demonstrated by the capabilities to withstand vibration from 30 g’s up to 3000 Hz and shock of 75 g’s for 6 msec (half-sine). The relays are hermetically sealed, emphasizing reliability in various conditions, and weigh a maximum of 0.09 oz (2.55 g).

Applications and Performance

The Series 114 relays have proven their effectiveness as excellent RF switches in the UHF spectrum due to their low intercontact capacitance and circuit losses. A notable application example are handheld radio transceivers, where factors such as optimal RF performance, compactness, low coil power dissipation, and high reliability, are critical for efficient Transmit-Receive switching.
