Cartridge Heaters Precautions
Cartridge Heaters Precautions for use
① Do not let the heater dry burn in the atmosphere. Otherwise, even if only heating part of the heater is exposed outside the object heated, the wire may break and cause a fire due to abnormal heating.
② Do not let the lead wire and insulator of the heater come into contact with water. Otherwise, it may cause electric leakage or short circuit.
③ The oil and grease used for processing holes in the heated part should be removed. Otherwise, abnormal heat may be generated due to carbonization.
④ An abnormally short ON-OFF cycle may have an adverse effect on the service life of the heater. It is recommended to use a controller controlled by PID.
⑤ Do not bend the nickel stranded wire and the lead wire repeatedly or pull them. (Forced pulling may cause wire breakage.)
⑥ Do not use a power supply with the voltage exceeding the rated voltage (V).
⑦ When removing the heater from the object heated, make sure to turn off the power first. Do not touch the heater immediately after turning off the power.
⑧ The temperature around the lead wire outlet shall be kept below 130℃.
⑨ When the flanged heater is used, the temperature around the flange shall be kept below 180°C.
⑩ Do not use it in the vacuum.
⑪ When heating, the heater will expand and may cause the heat-generating part to protrude from the mounting hole. It is recommended to fix the heater with screws.
⑫ Choose a voltage that is suitable for the operating environment. If you use a voltage that exceeds the rated value, the heater may be damaged.
* Other precautions for each type of cartridge heaters are recorded on each product page. Please make sure to follow the above precautions and operate the heater properly.

Cartridge Heaters Specifications Overview
Cartridge Heaters Heater Selection
① Determine the required heater heat (W).
It can be calculated with the following formula according to the mass, specific heat, rising temperature, and the heating time required to reach the set temperature of the object heated.
The efficiency varies with the heat preservation, thermal insulation, and settings of the heater, so it is difficult to calculate it correctly. Generally, the value of about 0.2 to 0.5 is preferred.
② Determine the number of heaters and the heat of each heater (W).
The number of heaters is subject to the size of the object heated, and the total heat (W) is the heat required by the object heated.
Example) Use 2 heaters of 550 (W) (1,100 W in total).
● Selection of the cartridge heater (P.2789 MCHK type)
④ Determine whether the Cartridge Heaters product satisfying the diameter (D), length (L), voltage (V), and heat (W) of the heater as required is available in the L Dimension・W (Power) Fixed Type (P.2789) and High Temperature Type (P.2790).
Note: For the power (W) of the L Dimension ・W (Power) Fixed Type, please select a product with the power (W) larger than the required heat (W).
● Measurement data of the temperature rise time by power

■Cartridge Heaters Overview
・The common specifications of MISUMI heaters have been standardized, which can satisfy the users’ needs of shortening the delivery time.
・ The temperature sensor and temperature controller, etc. required to control the heater can also be selected from the catalog.
■Basic structure (example)
・As shown in the figure below, the heater shall be used in combination with the temperature sensor and temperature controller.
・ Temperature adjusting procedure
■ Cartridge Heaters Example of heater use
① The temperature detected by the temperature sensor is regarded as the current value (PV) of the temperature controller.
② As shown in the above basic structure (an example), when the set temperature (SV) of the temperature controller is 80°C and the current value (PV) is 20°C, the temperature controller will apply a voltage (ON) to enable heating-up of the heater.
③ If the voltage (ON) is maintained all the time, the temperature will exceed the set value (SV) of 80°C. Therefore, when the temperature rises to around the set value (SV) 80°C, the temperature controller will stop applying the voltage (OFF).
When the current value of the temperature (PV) is

Cartridge Heaters Usage Method
Cartridge Heaters Mounting Method
● Please minimize the mounting hole gap of the heated metal block as much as possible.
When the metal block mounting hole is machined, it is recommended to keep the gap below 0.05 on one side.
* The size of gap between the heater and object heated will affect the service life of the heater. When a large gap will extend, a drilling hole can be used, but it is recommended that all heaters use reamed mounting holes. The temperature rise time may cause the response speed of the temperature controller to slow down. The temperature of the object heated is controlled below 300°C.
* The service life of the heater may change greatly due to the environment. The improper operating temperature and temperature adjusting method may cause wire breakage in a short period of time. Therefore, it is recommended to prepare the backup cartridge heater.
