SWITCH SUPPORT: Brass, matte-tin plated.
OPERATING TEMPERATURE: –30ºC to 85ºC.
SOLDERABILITY: Per MIL-STD-202F method 208D, or
EIA RS-186E method 9 (1 hour steam aging).
CONTACTS & TERMINALS: B contact material: Copper alloy,
with gold plate over nickel plate. See page A-11 for additional
contact materials.
DEGREE OF PROTECTION: IP57; Protection against harmful dust
deposit, full-scale voltage protection, temporary immersion.
TERMINAL SEAL: Epoxy.
NOTE: Any models supplied with Q, B, P, S, R or G contact material are RoHS compliant. For
the latest information regarding RoHS compliance, please go to: www.ittcannon.com/rohs.
PACKAGING: Surface mount switches standard in anti-static
tape and reel packaging per EIA 481-3, see page A-12 for
drawings and reel information. Tape and cover strip are
conductive for use near statically sensitive components,
consult Customer Service Center.
NOTE: Specifications and materials listed above are for switches with standard options.
For information on specific and custom switches, consult Customer Service Center.
CAUTION: PC mounting layouts and pads as shown are designed to be compatible with the
latest equipment and reflow techniques. Care should be taken in the design and location of
PC lands to suit individual needs. Orientation relative to reflow direction may significantly
impact solder joint integrity.
Build-A-Switch
To order, simply select desired option from each category and place in the appropriate box. Available options are shown
and described on pages A-8 thru A-11. For additional options not shown in catalog, consult Customer Service Center. All
models are process sealed to withstand machine soldering temperatures and pressure wash cleaning methods.
