159-157-RA1 Relay, Reed. Mercury Hg-Wetted, Form C.

The mercury-wetted contact relay represents one of the more sophisticated types of relays made today. The early pioneer work in mercury-wetted contact switching dates back to the 1950’s, as telephone laboratory scientists sought out the “perfect contact”.

Reed relays use an external electromagnet to control the reed switch. The contacts are of magnetic material and the electromagnet acts directly on them without requiring an armature to move them. Sealed in a glass tube, the contacts are protected from corrosion. Mercury-wetted relays are fast in operation and have relatively good load carrying capacity and long life. The mercury films are reestablished at each contact closure and contact erosion is eliminated. The mercury films are stretchable, there is no contact bounce and because it is a mercury contact, the contact resistance is very low and idea for low level switching applications.

A mercury-wetted reed relay is a form of reed relay that employs a mercury switch, in which the contacts are wetted with mercury. Mercury reduces the contact resistance and mitigates the associated voltage drop. For high-speed applications, the mercury eliminates contact bounce, and provides virtually instantaneous circuit closure. Mercury wetted relays are position-sensitive and must be mounted according to the manufacturer's specifications. Because of the toxicity and expense of liquid mercury, these relays have increasingly fallen into disuse.

The high speed of switching action of the mercury-wetted relay is a notable advantage. The mercury globules on each contact coalesce, and the current rise time through the contacts is generally considered to be a few picoseconds. However, in a practical circuit it may be limited by the inductance of the contacts and wiring. It was quite common, before restrictions on the use of mercury, to use a mercury-wetted relay in the laboratory as a convenient means of generating fast rise time pulses, however although the rise time may be picoseconds, the exact timing of the event is, like all other types of relay, subject to considerable jitter, possibly milliseconds, due to mechanical imperfections. The only major weakness of a mercury wetted contact relay is the necessity to mount the relay within 30° of a vertical position, due to its position sensitivity.

BIRD - 5-1357-3 Connector, Electronic Solder Eyelet, Rivet/Eyelet/Terminal.

Electronic eyelets are flanged tubular metal conductors inserted into a printed circuit board. They make electrical continuity between the circuitry on both sides of the board, and are an attachment point for soldering component leads.

Type: Solder.

Appears to be Silver Plated Brass (High thermal and electrical conductivity)

Metric Dimensions: Outside lip is 6.1mm OD, 2.9mm ID with a shaft 3.5mm round and 6.7mm tall under Lip.

Inch Dimensions: Outside lip is 0.240" OD, 0.114" ID with a shaft 0.138" round and 0.264" tall under Lip.

Applications: Secure High Current Electrical and Ground Connections or repairs to chassis and PWBs.

Chose the proper eyelet keeping the following in mind:
LUF The length of the eyelet barrel under the flange should be 0.020-0.035”/0.630-0.890mm greater than the thickness of PCB(this allows the for the right length after the flange is formed)
ID Eyelet inside diameter should be 0.003-0.020”/0.075-0.500mm greater than the component lead diameter for proper fit of  the eyelet through-hole component lead.
FD The flange diameter should be sized so that it does not protrude out onto other pads or conductors in the vicinity
OD The clearance in the PCB hole should allow the eyelet to be inserted without undue force but, but should not exceed 0.125mm greater than the eyelet outside diameter.

Applications: Wind Turbines, Linear actuators, Microphone assemblies, Servo motors, Tape recorders, Alternators, Pacemakers, DC motors, Flow meters, Holding Assemblies, Lifting Magnets, Magnetic Fanners.

Extreme caution must be taken when working with rare earth magnets. Magnets larger than a few centimeters are strong enough to cause injuries to body parts pinched between two magnets, or a magnet and a metal surface, even causing broken bones. Magnets allowed to get too close to each other can strike one another with force to chip and shatter the brittle material, and the flying chips can cause injuries.
