NTC Thermistor in TO-220 Package for DIP PCB Mounting

Focusens FHT20 series temperature humidity transmitter is a cost effective, highly accurate and reliable solution for measuring relative air humidity and temperature. The enclosure minimizes installation costs and provides outstanding protection against contamination and condensation, thus ensuring flawless operation. The FHT20 use the reliable humidity / temperature Sensirion sensor element SHT21 with excellent long term stability and resistance against pollutants. In combination with a long calibration experience, the FHT20 provides a measurement accuracy of ±3%RH and is available for wall-mounted with current, voltage output.

Focusens MFP series HVAC averaging temperature sensor is exquisited designed for duct or pipe applications for air or water where accurate average temperature measurement is required. By using optimized sensing architecture, flexible sensing tube distribution across the airflow or pipe section, it provides a more representative temperature signal than a single-point sensor, especially in large ducts or uneven airflow conditions.

MFT Series temperature sensor made with tubular SUS304 SUS316 house and have round jacket cable. Two rolling grooves was made to help the contact between house and cable water tight enough, varisous probe size and different working temperature range available on request.

Focusens MF58 series NTC thermistor is high precision NTC thermistor sealed in glass. There are two lead type of MF58 thermistor, the radial lead type with ordering code MF58A and MF58B is sealedas small glass bead diameter Max.1.5mm and 2.2mm respectively,the axial lead part MF58C is packed in standard DO35 glass. This chip in glass thermistor have standard and small size. With advanced ceramic sintering and glass sealing technique it have advantage of high precision, miniture size,fast response and reliable stability especially under 100-250'C high temperature. The MF58 thermistor is widely used for temperature sensors as well as used directly on PCB or circuit for precision temperature sensing.

MF5A-5 Series miniture NTC thermistor is made with epoxy resin coating ,and insulation lead wire like PVC wire, teflon or Kynar wire. It has advantages of miniture size, high precision and fast response.   

Focusens FHR4213 series interchangeable NTC temperature sensor are specifically used for patient temperature monitoring . Different connector interface available to be compatible with different monitoring equipments , typlically 6.35mm , 3.5mm and 2.5mm jack phone plug, mono or dual track versions available on requests.

Focusens PTC thermistor is a leader in the field of motor protection with excellent quality. Its core feature is the sudden increase in resistance at critical temperature. It is high quality and low price, and performs well in heavy-duty motors. To avoid the risk of direct interruption of large currents, the PTC sensor intelligently monitors the temperature and provides high-resistance protection when exceeding the threshold, safely cutting off the circuit and preventing the motor from overheating.

Focusens MFP-6 series Screw Threaded NTC Thermistors are made for surface temperature measurement, sensing, and control. It is easily mounted sensor with brass or aluminum metal screw.  It is especially ideal thermal solution when good electrical insulation and good thermal contact with the chassis or wall is required.
