Sipha Sensors

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.

Features

• Non contact actuation

• Magnetic coded sensing

• Four housing styles

• Must be operated with its own safety control unit
