ESTABLISHED RELIABILITY T 2 R RELAYS
Series ER412 & ER432 Electromechanical Relays
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 specifi cally for high-density PC board
mounting, its small size and low coil power dissipation make the ER412 relay one of the most versatile
ultraminiature relays available.
The Series ER412D and ER412DD relays have internal discrete silicon diodes for coil suppression and
polarity reversal protection. The hybrid ER412T relay features an internal silicon suppression diode and
transistor driver. This hybrid package reduces required PC board fl oor space by reducing the number of
external components needed to drive the relay.
The sensitive ER432 relay has a high resistance coil, thus requiring extremely low operating power (200 mw
typical). The advantages of reduced heat dissipation and power supply demands are a plus.
The Series ER432D and ER432DD relays have internal discrete silicon diodes for coil suppression and
polarity reversal protection. The hybrid ER432T relay features an internal silicon suppression diode and
transistor driver. This hybrid package reduces required PC board fl oor space by minimizing the number of
external components needed to drive the relay.
• All welded construction
• Unique uni-frame design providing high
magnetic effi ciency and mechanical rigidity
• High force/mass ratio for resistance to
shock and vibration
• Precious metal alloy contact material with
gold plating assures excellent high current
and dry circuit switching capabilities
