All dimensions shown are in inches (millimeters) unless otherwise specified.

Laird Technologies announces the addition of a battery contact product line. These

high-performance battery contacts are suitable for coin battery applications,

battery pack contact applications and AA/AAA battery applications.

Supplied in heat treated beryllium copper, the contacts offer superb contact

force and a large compression range. Heat treatment of beryllium copper

significantly reduces the material’s internal stress, thereby allowing a wide range

of compression to accommodate variations in battery size and placement.

• All contacts are surface mounted and require solder pads, except for 97-490

which is thru-pin mounted and requires mount holes

• Available in tape and reel packaging for high volume pick-and-place assembly

• Available in a variety of plated finishes for galvanic compatibility

• Custom designs can be developed by calling our application engineers

97-487/97-488 COIN BATTERY APPLICATIONS

SIDE VIEW

TOP VIEW

97-487/488 COIN BATTERY APPLICATIONS

These contacts are surface mount soldered to a PC board. Separately mounted

contacts can be positioned to accommodate a wide range of battery sizes.

The coin battery is captivated by the device housing and held in contact.

These contacts are provided with gold plating as standard.

Typical applications for the 97-487/488 contacts are low powered portable

devices, such as pocket organizers, portable medical devices and any device

that uses coin batteries.

97-489 BATTERY PACK CONTACTS

These contacts are soldered onto a PC board and protrude through cutouts

in a plastic housing. Contact is made as the prismatic battery pack mates

with the housing and pushes the contacts back into the cutouts.

The contacts are provided with nickel plating as standard. Gold plating

is available.

Typical applications for the 97-489 contacts are portable devices with removable

battery packs, such as video cameras, radios, power tools, etc.

97-490 AA/AAA BATTERY CONTACT APPLICATIONS

These contacts mount onto a PC board and protrude into a cutout at the

end of a battery well. Backup ribs must be provided in the plastic molding.

The contacts are provided with nickel plating as standard. Gold plating is

optionally available.

Built-in stop protects over-compression damage. Applications would include

any device using AA or AAA batteries, particularly devices with high mechanical

and electrical performance such as medical, GPS and surveying instruments.
