S-Series Limit Switch with Integral Solenoids
The S- Series combines a compact enclosure with limit switches, visual indication and integral solenoids for
position indication plus valve actuator control and 3-position control for 3-way ball valves and 180 degree
actuators. NAMUR proximity switch options and EEx ia solenoid valve also make the S-series suitable for
use in intrinsically safe applications.
The S- Series integral single or double 5-port, 4-way solenoid valves dramatically reduce automation
assembly time and envelop dimension of package. Factory pre-wiring ensures reliable startups and long-
term reliability.
The S- Series is available with a variety of switches and feedback choices including: electromechanical,
inductive proximity, NAMUR, NPN, PNP and hermetically-sealed proximity dry contact switches; AS-i digital
communication or a 4-20 mA position transmitter.
