DESCRIPTION
DPDT basic relay
DPDT relay with internal diode for coil transient suppression
DPDT relay with internal transistor driver and coil transient suppression diode
• Advanced cleaning techniques provide maximum assurance of internal
cleanliness.
• Precious metal alloy contact material with gold plating assures excellent
high current and dry circuit switching capabilities.
The Series 732D relay has an internal discrete silicon diode for coil
transient suppression. The hybrid Series 732TN relay has an internal
silicon diode and transistor driver. The integrated packaging of the relay
with its associated semiconductor devices greatly reduces PC board floor
space requirements as well as component installation costs.
By virtue of its inherently low intercontact capacitance and contact circuit
losses, the 732 has proven to be excellent ultraminiature RF switch for
frequency ranges well into the UHF spectrum. A typical RF application for
the TO-5 relay is in handheld radio transceivers, wherein the combined
features of good RF performance, small size, low coil power dissipation
and high reliability make it a preferred method of Transmit-Receive
switching
The TO-5 relay, originally conceived and developed by Teledyne, has
become one of the industry standards for low-level switching from dry circuit
to 1 ampere. Designed for high-density PC board mounting, the Series
732 relays are some of the most versatile ultraminiature relays available
because of their small size and low coil power dissipation.
The following unique construction features and manufacturing techniques
provide excellent resistance to environmental extremes and overall high
reliability:
The 732 feature:
•All welded construction.
• Unique uni-frame design providing high magnetic efficiency and
mechanical rigidity.
• High force/mass ratios for resistance to shock and vibration.
