Solderless LED
Socket, Type CM 29 JUN 11 Rev D
All numerical values are in metric units [with U.S. customary units in brackets]. Dimensions are in millimeters. Unless
otherwise specified, dimensions have a tolerance of ±0.13 [±.005] and angles have a tolerance of ±2°. Figures and
illustrations are for identification only and are not drawn to scale.
1. INTRODUCTION
The Solderless LED Socket, Type CM provides an integrated electrical and optical solution for the CREE
XLAMP MP-L LEDs. The socket enables power to be brought to the LED by using either a LED-to-board
solution or a LED-to-wire solution. The socket also has features to mount the TYRA Series of reflectors from
LEDIL. The Solderless LED Socket is mounted using three No. 4 or M3 screws.
The LED--to--wire solution enables customers to bring power by using the MiniCT co nnector which plugs into
the socket. The board--to--board solution enables power to be bro ught to the LED by providing an electrical
connection between the electr ica l pads on the LED substrate and pads on the printed circuit (pc) board. The
LED to inverted wire solution enables the customer to bring power from underneath the pc board by wiring the
MiniCT connector which plugs into the socket. Refer to Application Specification 114-5245 for the MiniCT
connector.
When corresponding with personnel, use the terminology provided in this specification to facilitate your inquiries
for information. Basic terms and features of this product are provided in Figure 1.

2. REFERENCE MATERIAL
2.1. Revision Summary
The new company logo was applied to this specification.
2.2. Customer Assistance
Reference Base Part Number 2106946, and Product Code L836 are representative numbers of the Solderless
LED Socket, Type CM. Use of these numbers will identify the product line and expedite your inquiries through a
service network established to help you obtain product and tooling information. Such information can be
obtained through a local company representative or, after purchase, by calling the Tooling Assistance Center or
Product Information number at the bottom of page 1.
2.3. Drawings
Customer drawings for specific products are available from the service network. The information contained in
customer drawings takes priority if there is a conflict with this specification or with any other technical
documentation supplied by the company.
3. REQUIREMENTS
3.1. Safety
Do not stack product shipping containers so high that the con tainers buckle or deform.
3.2. Storage
A. Shelf Life
The Solderless LED Socket should remain in the shipping containers until ready for use to prevent
deformation. The socket should be used on a first in, first out basis to avoid storage contamination that
could adversely affect performance.
B. Chemical Exposure
Do not store the socket near any chemical listed below as they may caus e str es s cor ro sio n cra ck ing .
Alkalies Ammonia Citrates Phosphates Citrates Sulfur Compounds
Amines Carbonates Nitrites Sulfur Nitrites Tartrates
3.3. Features
The Solderless LED Socket has a pocket in the housing which captures the LED substrate and enables the
socket to be properly aligned with the LED. Th e socket is of fered with and without latches for the optics. Sockets
without the latches can be used by customers who do not intend to use an optic or want to use their own optic.
The socket has three mounting holes and can be mounted using three No. 4 or M3 screws.
3.4. PC Board Layouts
A. Material
The pc board material shall be glass epoxy (FR-4, G-10) or metal--c lad pc board. Contact the Product Infor-
mation Center or the Tooling Assistance Center at the number listed at the bottom of page 1 for
suitability of other board materials.
B. Tolerance
The maximum bow of the pc board shall be 0.03 mm over the length of the connector.
C. Layout
The mounting holes in the pc boar d must be precisely located to ensure proper place ment and optim um per-
formance of the connector. See Figure 2.
NOTE

3.6. Mounting the Solderless LED Socket
Once the LED has been mounted (either by soldering it or by using a thermal epoxy), the socket is placed over
the LED substrate . T he sock et ha s a po cke t in the bas e which helps align it with the LED substrate. Using th e
openings in the socket, en sure that it is properly aligned . Once the socket has been aligned gen tly press it down
and screw it in place. The socket can be mounted using three No. 4 or M3 screws. See Figure 4. T ighten the
screws to a torque of 0.28 to 0.45 N-m [2.5 to 4.0 in.-lbf].

When pushing down on the socket, care must be taken to not damage the LED and the latches on the socket.
CAUTION
!
To protect against corrosion, screws from ferrous metals (other than stainless steel) should be zinc plated or have an
equivalent protective coating.
CAUTION
!
The company recommends using pan head screws. The use of flat head screws is not recommended.
3.7. Mounting the LEDIL Optics
The Solderless LED Socket has snap features which allow for easily attaching the TYRA se ries of optics from
LEDIL.
CAUTION
!
The socket must be secured in place with the screws before the optics can be attached.
To attach the optics, align the snap features on the socket with corresponding features on the optics. Once
aligned, push the optic down until the latches have snapped into place. See Figure 5.
