RTD-880-APP-1000OHMS 1000 Ω at 0°C, 0.00375 temp coefficient
Notes: The “A” dimension can be immersed in liquid up to the mounting flange. The two lead wires add 0.30 Ω of lead resistance to the circuit.
For leads with Molex pin 03-06-2023 and male Molex 02-06-2101, add “-MOLEX” to the model number and $4 to the price. For high-temperature
miniature connectors with flat pins, add “-SHX” and $8.50 to price. For ultra high-temperature connectors with solid round pins, add “-NHX” and
$11 to price.
Ordering Examples: RTD-870-1000OHMS-NHX, 100 Ω, 0.00385 DIN platinum element and high-temp solid pin connector, $70.
RTD-880-APP-1000OHMS-MOLEX, 1000 Ω, 0.00375 platinum element and Molex pins attached, $58.
