NTC thermistor sensor for thermodilution catheters, UL approval

Brief Introduction
MF5A series of miniature thermistors are 6,000 ohm/14,000 ohm composites encapsulated in polyimide tubes. Their leads are made from solid copper and twisted triplet. The standard overall lengths of these sensors are 6 inches, 24 inches or 36 inches. F-micro miniature thermistor sensor has been traditionally designed for use within medical applications, but ideal for the emerging wearable technology market.

2-part epoxy fill, E&C 2651MM / CAT 9.
Parts are calibrated at 37ºC with resistance value of thermistor printed on a label attached to spool. 22 ohms of lead resistance is subtracted from calibration. 40 AWG wire contributes 4.37 ±0.3 OHMS per foot.
Separate the conductors from dimension indicated
Remove insulation from each conductor as shown. Clean & trim away all insulation. No filaments or uneven patches permitted. Hand trim with tweezer strippers as required.

Production Process

Note: temperature sensors for Food & Medical Applications since most products for food and medical applications directly relate to the healthy and lives of people, their quality is strictly specified to be ''clean and sanitary'' in the food Sanitation Act and Pharmaceutical Affairs Act. Especially, in recent years, international restrictions such as HACCP and GMP have been applied in many cases and the importance of temperature measurement has been increasing.
For the temperature sensors which are used in manufacturing processes, ''sanitary design is a mandatory condition in order to retain a clean manufacturing environment without foreign substances and a microbiologically.

Standard Package for NTC thermistor
Assembly is provided wound on plastic spool (Not shown) and packed 30 per tray.
