Moniteur Switch and Sensor Selection Guide
Non-Contact TTL SPDT (proximity-type) Switches
These hermetically sealed switches set the standard for reliability. Tungsten TTL switches are used for high current AC and DC applications with a rating of 3A at 120 VAC and 2A at 24 VDC. Choose Rhodium TTL for low voltage / low current DC and Intrinsically Safe applications. Optional LEDs are also available on the Krystal TTL with Rhodium contacts. NOTE: Switches with Tungsten contacts are not recommended for DC signals lower than 50 mA. Specifications
NAMUR, PNP or NPN Inductive Sensors

A wide variety of industry standard sensors is available to interface with control systems found in today's modern process plants. Specifications
