INTERNAL CONSTRUCTION

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

UNI-FRAME

ultraminiature relays available.

The following unique construction features and manufacturing techniques

provide excellent resistance to environmental extremes and overall high

reliability.

ARMATURE

LOWER

STATIONARY

CONTACT

• 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.

MOVING

CONTACT

• Precious metal alloy contact material with gold plating assures excellent

high current and dry circuit switching capabilities.

ENVIRONMENTAL AND

PHYSICAL SPECIFICATIONS

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.

Vibration

(General Note 1)

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.
