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.
Operating Temperature
S1, S2, S3 -10°C to +55°C (+14° to +131°F)
S4 (GD2) -25°C to +125°C (-13° to +257°F)
Enclosure Protection
S1, S2, S31 IP67 (NEMA 6P)
S4 (GD2) IP67 (NEMA 6P)

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.
