EAC's thin SIP series SN is the answer for those areas in which high performance coupled with a budget price is desired.

These relays are designed for mounting on 0.200 inch centers. They are manufactured using techniques that virtually eliminate weak link failures such as internal coil lead and coil wire soldering and other human error factors.

This relay design has the following features:

1. Automatic insertion design
2. Internal diode optional
3. "RF" capability
4. High isolation resistance
5. Narrow profile
6. Epoxy construction, unaffected by cleaning fluids
7. Wide range current switching

These relays are constructed on a lead frame. All internal solder connections are made using a high temperature solder. A proprietary weld process is used to join the reed switch to the lead frame.

The prime cause of failure of a relay is what is called "contact resistance". EAC, being a pioneer in the field of successful detection and elimination of this phenomenon, by the use of "dynamic contact resistance" testing of mechanical synchronous demodulator contacts (choppers) applied this knowledge to relays. We ask that you contact EAC for Bulletin TEST A for a further description of these testing procedures.

In addition to the testing for dynamic contact resistance, we test each relay for the following:

1. Pick-up
2. Drop-out
3. Coil resistance
4. Static Contact Resistance
5. Contact Resistance Stability
6. Insulation Resistance

This series of relays utilizes the latest in design technology allowing it's use between an object to be tested and the testing device. A variety of the series is available with a coaxial 50 ohm shield for use in those areas requiring the ultimate in shielding.

The heart of the relay is a tiny switch capable of performing a low level switching function of less than 1 volt and 10 milliamperes for more than a billion operations without executing a "contact stick" or showing any significant change in contact resistance. Contact material is ruthenium.

For assistance with your specific needs, you need only contact the EAC Customer Service.

Reed Relay Reliability Program
Rigorous pre-testing of the reed switch under actual low level operating conditions is just the first step in EAC's continuing efforts to build the most reliable reed relays in the industry. The coils, for example, must pass no less than three inspections prior to reaching final assembly. In addition, each major construction operation is monitored by experienced inspectors who take pride in helping produce the most reliable relays technically possible.

Testing Methods
100% testing of the reed switches before use and of the relays when finished is patterned after MIL-Q-45208. MIL-R-5757 test methods are used. Static and dynamic relay operation to verify proper performance and to assure a trouble free life is undertaken as a part of the final testing operation to insure that each EAC reed relay conforms to specifications.

Our Program Of QA
Quality Assurance at EAC is the by-word that we live by. EAC has achieved many awards for excellence of quality and delivery. This is assured to the customer by the implementation of the famous Japanese Assembly Methodology and what is now known as Total Quality Control. It takes dedication to excellence to make the program work. However, at EAC, we have found that the amount of returned relays for all reasons by our customers has dropped to less than .07% of shipments. A truly remarkable achievement.
