Product description
Plug-in, latching magnetic reed switch for applications that need to be
adjusted at the place of installation. The base is clipped into a C rail.
The shock-sensitive switching element is then plugged in on site and
the switch adjusted.
The NC or NO function depends on the actuating direction and the
polarity of the actuating magnet. The actuators for the magnetic safety
sensors must be ordered separately.
