ELECTRO-OPTIC TYPE ELS-1100HT Handles Temperatures to 212°F Slightly larger than the ELS-1100, the " HT " or High Temperature version is made from high performance Isoplast® plastic. While maintaining broad chemical compatibility, these units also handle fluid temperatures to 212°F. They feature 3/8-18 NPT mountings and the shortest of any of our plastic electro-optic switch bodies - HTS versions are a mere 1/2 " long! File No. E108913 Typical Applications * Coolant reservoir monitoring * Medical diagnostic and sterilizer equipment * Low lubricant warning on machine tools * Low level warning in hydraulic reservoirs Specifications Materials Housing and Prism Max. Operating Pressure Operating Temperature* Current Consumption Output Repeatability Isoplast® 0 to 150 psi (0 to 10.3 bar) −40°F to +212°F (−40°C +100°C) 45 mA, Approximately TTL/CMOS Compatible. Transistor Output with 10K Pull Up Resistor May Sink 18 mA. 12 VDC input power units switch a maximum 5 VDC on output ±1 mm * These switches are not for use in freezing liquids or steam/high condensation environments.
