min.

ELECTROSTATIC DISCHARGE (ESD) RESISTANT OPTION:

M3 & S3 insulating actuator only: 9,000 V DC min. @ sea level,

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.

Materials

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.

NOTE:

Specifications and materials listed above are for switches with standard options.
