OMRON B3AL1000P

Long-stroke Tactile Switch (SMT)
B3AL
Long-stroke Tactile Switches with High
Operating Forces and Long Life.
● High operating force also providing long life.
(OF = 3.5 N {357 gf}, Durability = 1 million
operations)
● Long stroke achieved by using a rubber plunger.
RoHS Compliant

Precautions
■
Note:
Be sure to read the precautions common to all Tactile Switches for correct use.
Precautions for Correct Use
■
soldering
Do not exceed the following terminal temperature profile during
soldering in a reflow oven.
Operation
• Do not repeatedly operate the Switch with excessive force.
Applying excessive pressure or applying additional force after
the plunger has stopped may deform the disk spring of the
Switch, resulting in malfunction.
• Be sure to set up the Switch so that the plunger will operate in a
straight vertical line.
If the plunger is pressed of-center or from an angle it may cause
deformation or damage to some parts.
260°C
220°C
180°C
• We recommend using a round bar with a diameter of at least 3
mm as the actuator.

Washing
The Switches are not sealed, and cannot be washed.
Doing so will cause the washing agent, together with flux or dust
particles on the PCB, to enter the Switch, resulting in malfunction.

Dust Countermeasures
Do not mount or use the Switch in areas that are subject to dust.
If dust is unavoidable, protect the Switch with a sheet or other
countermeasure.
Water and Drip Resistance
The switch is not water or drip resistant.
Do not use it in locations subject to water.
