actuator to terminals. F1 conductive bushing only: Dissipates
up to 20,000 V DC from actuator to ground. M3 & S3 actuator
and F1 bushing options are not recommended for use together.
DIELECTRIC STRENGTH: 1000 Vrms min. @ sea level.
OPERATING TEMPERATURE: –30ºC to 85ºC.
SOLDERABILITY: Per MIL-STD-202F method 208D, or
EIA RS-186E method 9 (1 hour steam aging).
DEGREE OF PROTECTION: IP57; Protection against harmful dust
deposit, full-scale voltage protection, temporary immersion.
PACKAGING: Surface mount switches are shipped in tape and reel
packaging, see page G-35 for drawings and reel information.
CASE & BUSHING: Glass filled nylon 6/6, flame retardant, heat
stabilized (UL 94V-0). SA surface mount: High temperature
material, glass filled 4/6 nylon, flame retardant, heat stabilized
(UL 94V-0). F1 conductive bushing option is impregnated
with carbon fibers.
ACTUATOR: M3 & S3 anti-static actuator: Nylon 4/6, black standard
(UL 94V-0). All other actuators: Brass, chrome plated. Internal
o-ring seal standard with all actuators.
SWITCH SUPPORT: Brass, tin plated.
CONTACTS & TERMINALS: B contact material: Copper alloy,
with gold plate over nickel plate. Q contact material: Copper
alloy, silver plated. See G-35 for additional contact materials.
TERMINAL SEAL: Epoxy.
NOTE: Any models supplied with Q, B, G, P or R contact material are RoHS compliant
and compatible. For the latest information regarding RoHS compliance, please go to:
www.ittcannon.com/rohs.
NOTE: Specifications and materials listed above are for switches with standard options.
For information on specific and custom switches, consult Customer Service Center.
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 G–31 thru G–35. For additional options not shown in catalog, consult our Customer Service Center. All
models are process sealed to withstand machine soldering temperatures and pressure wash cleaning methods.
