SIL3 Functional Safety Incremental Encoders
With a robust and reliable design resulting in a wide range of secure products, which can be used in several types of configuration.

Any automated system potentially poses a risk to people, property or the environment. For this reason a number of safety measures have been taken. Safety standards have been created with one thing in mind: limiting risk.

With these standards as a framework, functional safety can, after a risk analysis, provide appropriate protection. Hazards are anticipated during the system design phase and are dealt with before they occur. These standards have evolved to increase the safety level and have been applicable since 2012.

UL Approved*  D Size Form C (Changeover) Relay

•  100W switching power.
•  Changeover contacts.
•  PCB Mount.
•  Available with or without a magnetic screen.
•  Tungsten contacts for high power switching.
•  Large package size.
•  Up to 4A carry current.
•  Often used in applications which require circuit protection or circuit breakers.

The D1 series is a reed relay with changeover contacts which are often used in safety critical applications.

The switching is achieved through the use of high vacuum reed switches with Tungsten contacts and make these relays suitable for high reliability applications, such as test equipment and high voltage power supplies.

These are PCB mount relays, though custom options may be available on request.

*Consult factory for UL ratings:
These products have been UL approved for use as per pollution degree 2 classification.

S Size Form C (Changeover) Reed Relay

• Compact footprint.
• Changeover contacts.
• PCB Mount.
• Available with or without magnetic screen.
• Up to 3W switching power.
• Up to 1.2A carry current.
• Small package size with compact footprint.
• Rhodium contacts for low contact resistance and high durability.
• Often used in applications which require circuit protection or circuit breakers.

The S3 series is a compact reed relay with changeover contacts which are often used for safety critical applications.

Low contact resistance, through the use of Rhodium contact reed switches, makes the S series suitable for many high voltage applications at DC and low frequency, where performance and reliability are paramount.

These are PCB mount relays, though custom options may be available on request.

UL Approved* Miniature SIL Reed Relay with Form B (N/C) Contacts

•  Single-in-line package
•  1.5kV Isolation Voltage across contacts
•  1.3A carry current
•  Up to 1000V switching voltage

The S1 Form B series is a miniature high voltage single-in-line reed relay for applications where space saving is a prime consideration, with normally closed contacts.

The coil pins are positioned near the centre of the relay while the contact pins are near the ends to give improved isolation between the high voltage contacts and the low voltage coil.

The RSF150 series of vertical float switches are manufactured from a choice of 4 different materials to ensure compatibility with the widest range of liquids.  Nitrile gaskets are supplied as standard, but can be specified from alternative materials to suit the application.    And they are now available with the popular 4-pin M12 round connector - to provide a convenient and foolproof electrical connection.

As with many other Cynergy3 float switches, the float can be readily inverted in order to offer either normally open or normally closed operation, and the switch itself can be specified to have either 25VA or 100VA capacity.

All float switches in the series have either WRAS or UL (or both) approvals.

Cynergy3 can also supply the mating plus and cables and these are available in various lengths and with either straight or elbowed plugs.
