Description
With the increasing speed and complexity of applications a simple
magnetic switch may be insufficient to meet the increased risks,
therefore Sipha’s design incorporates several magnetically sensitive
elements which must be triggered in a particular sequence to operate
correctly. The Sipha sensor, designed to operate with its own
actuator, helps prevent defeatability by a simple magnet.
The Sipha with its moulded-in brackets and diminutive size, is
extremely versatile and simple to install. The Sipha Sensor must be
connected to the Sipha control unit giving a monitored circuit. For
high-risk applications the control unit is used with a single sensor to
give a high-integrity system. For other applications, multiple sensors
(including mechanical switches) can be connected to one Sipha
control unit. Sipha has facilities for connecting a manual reset button
and for monitoring external devices such as contactors.
Four types of sensors and actuators are available incorporating
different operating distances and physical sizes.
