NOSHOK have increased versatility, and improved repeatability and contact ratings with the upgrade of their 200 and 300 Series Mechanical Switches.
Norshok says that both the 200 and 300 Series Switches now provide an increased switching frequency of 100 cycles per minute, and improved switching repeatability of ±2.0%. They also feature superior contact ratings: AC up to 250 V – 4 A, and DC up to 28 V – 2 A, and are RoHS compliant, claims Norshok.
The 300 series switch features further improvements claims Norshok, saying that it has adjustable hysteresis (10-30% of switch point), the 200 Series Switch function is now SPDT.
Norshok says that the 200 series switches come in either stainless steel or brass housings with gold contacts for low switching currents, and also says that the 200 Series Switch is constructed with an external adjustment screw for ease of setting the switching point on-site. This switch operates using a high quality diaphragm or piston element to open or close a micro switch.
The 300 Series Switch features a rugged zinc plated steel housing and process connection, and uses proven diaphragm or piston type sensing technology to provide excellent reliability, repeatability, and affordability, claims Noshok. Noshok also says, Its micro switch contacts are silver plated for extended service life and exceptional dependability, and its switching functions are field adjustable while under pressure.
