SQ4

SQ4 SERIES

Safety Leak Sensor for Water & Caustic Chemical

Category 4 Rated - when used in combination, the SQ4-A sensor and SQ4-C11 controller meet Category 4/PLE/SIL3 requirements under ISO 13849-1:2008
Two-Stage Detection - dual sensing outputs provide both a warning and safety-critical output for differentiation of leak severity
Multiple Sensor Inputs - Up to four sensors can be connected to each controller
Independent Operation - Sensor heads can be used independently of the controller, meeting a Category 1 rating

Safety Input Function - Allows daisy chaining of multiple controllers along with safety peripherals such as e-stop and door switches

Sunx is pleased to announce the new SQ4 Series of safety leak sensors. The SQ4 Series is one of the first leak sensors in the industry to earn safety certification, demonstrating that it delivers safety performance of the highest caliber. Featuring a two-stage detection system for improved productivity, the SQ4 simplifies preventative maintenance and maintenance planning.
