TO-5 RELAYS
SENSITIVE DPDT
DESCRIPTION
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, its small size and low
coil power dissipation make the 432 relay one of the most versatile
ultraminiature relays available.
The following unique construction features and manufacturing techniques
provide excellent resistance to environmental extremes and overall high
reliability.
• All welded construction.
• Unique uni-frame design, providing high magnetic efficiency and
mechanical rigidity.
• High force/mass ratios for resistance to shock and vibration.
• 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 432D and 432DD relays have internal discrete silicon diodes for
coil suppression and polarity reversal protection. The hybrid 432T relay has an
internal silicon suppression diode and a transistor driver. This hybrid package
reduces required PC board floor space by reducing the number of external
components needed to drive the relay.
By virtue of its inherently low intercontact capacitance and contact circuit
losses, the 432 relay has shown its worth as an RF switch for frequency
ranges well into the UHF spectrum (see Figure 1). In addition, the sensitive
Series 432 relay has a high resistance coil, thus requiring extremely low
operating power (200 milliwatts, typical at room temperature). The advantages
of reduced heat dissipation and power supply demands are a plus.
