Surge Protection for Proximity Sensors/Switches SLT-HEB Series Sensor Protector

The SLT-HEB Series of protectors is available as either a 4, 5, 8 or 10 Wire SPD (surge protective device) unit that will interface directly, in series, with 4 or 5 pin M12/Euro/DC Micro Connectors. Models are unidirectional due to connector configuration; where the male connector equals Line Side (unprotected) and the female equals the Load Side (Protected). Circuit performance is bidirectional.

The SLT-HEB is designed to protect Sensors & Proximity Switches on Roller Coasters, Ski Lifts, Gondolas and other people-movers.

Plug-in Surge Protectors

Secondary Protection 
Today's business lifestyles demonstrate how integral electronic equipment has become to our standard of living.  Everyday we use computers, telephones, facsimile machines, networks and entertainment equipment.

This equipment contains sensitive microchips or circuits that are easily damaged by surges.  Many of these surges are created within the facility itself. S
ervice entrance SPDs can not furnish protection to safeguard sensitive electronics from internally generated surges, so additional levels of protection, such as high quality secondary protectors, should be placed on all equipment and systems deemed valuable.
