Description
The Elf is a tongue (or key) operated safety interlock switch
designed to fit at the leading edge of sliding, hinged or liftoff guards.
The Elf ’s unique miniature housing (only 75
×
25
×
29mm) makes it
the smallest interlock currently available. It is designed for smaller
machines such as printers, copiers or domestic machinery which,
until now, have been unable to use safety interlocks due to space
restrictions.With its dual entry slots and rotatable head, the versatile
Elf can offer up to eight different actuator entry options.
Operation of the switch is achieved through the insertion of a
specially profiled stainless steel key that is permanently mounted to
the guard door. The semi-flexible key allows the Elf to be used on
small radii doors (60mm or 2.36in).
The Elf is available with 2 N.C. or 1 N.O. and 1 N.C. safety contact
and conduit entry (1
×
M16 or connector style) sealed to IP67
(watertight and dustproof). A blanking plug is supplied for the
unused key entry.

Environmental protection: IP67
Conductive pollution occurs, or dry, non conductive pollution occurs which
becomes conductive due to condensation.
Applications
Note:
Lift-off guards require good alignment when using
tongue actuated interlock switches.
IMPORTANT: It must not be possible to lift the guard
without actuating the interlock. An interlock on either
side may be required.

关于PWM波形的问题
波形有死区,如何计算输出PWM波形的占空比? 我在程序中定义了死区,未加死区的占空比是34%,周期是50微秒,那么高电平时,有效脉宽是17微秒。可是加了死区后(死区是8微秒),高电平变为17-8= ......
