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, the Series
732 relays are some of the most versatile ultraminiature relays available
bec au se of t he ir sm all s ize an d lo w c oil p owe r dis si pat io n.
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 eff iciency and
mechanical rigidit y.
• Hig h fo rc e /mas s ra ti os f or r esi st an c e to sh oc k an d vi br ati on.
• Advan c ed c l ea nin g te ch ni qu es p rov id e ma x im um as s ura nc e of i nte r na l

GENERAL NOTES
1. Relay contacts will exhibit no chatter in
excess of 10 μsec or transfer in excess
of 1 μsec.
2. “Typical” characteristics are based on
available data and are best estimates.
No on-going verification tests are
performed.
3. Unless otherwise specified, parameters
are initial values.
4. Relays can be supplied with a spacer
pad. See appendix.
