Features:

Infrared setting
IQM series actuators adopt advanced infrared remote control technology (IrDA), infrared setting tool can set and diagnose actuator through sealed indication window without removing the electric cover. The communication distance between setting tool and window is within 0.75 meter. Infrared setting tool is instinsicailly safe design and can be used in hazardous environment. 

Non-intrusive design
The IQM actuators take the non-intrusive design. The site setting operation can be accomplished by using an infrared setting tool without removing the electric cover. Consequently, the internal electrical control parts can be protected from the site pollution. The design for local operation discards the traditional moving shafts penetrating the control enclosure and takes the hall magnetic sensor technology to control the actuator.

Accurate torque measurement

IQM Series adopts its unique torque measurement system to ensure the overload protection of actuators and indicate the torque variation by LCD. The precise torque value is decided by the electronic signal converted from the reaction force of motor shaft's thrust transferred by torque sensor, thus solves the problem of calculating the torque according to the changes of power frequency, voltage and temperature.

Precise valve position measurement
IQM actuator takes advanced hall-effect incremental absolute encoder to measure the valve position. The adoption of non-contact encoder design can avoid the disadvantages of traditional potentiometer, which is easy to wear and has short life. It increases the reliability and lifetime of the actuator. The setting range of the encoder is 2.5~150,000,000 circles. 
Duty cycle
Duty cycle covers S2 to S4.
Noise
Independent tests have shown that the noise did not exceed 61dB (A) within 1M distance.

High-definition LCD
IQM actuators incorporate a unique high-definition liquid crystal display. Large display window with backlight enables users to see valve position, torque and functional status at a long distance.
Life test
Standard IQM life test is based on 10,000 times open /close/open cycles (500,000 output turns) with maximum seating torque at stroke end and an average of 1/3 maximum seating torque during stroke. Actuator is stalled 25 times against a solid object to prove its durability.
Designed service life
At the rated torque of on-off actuator, the shortest lifetime is 30,000 times open/close/open cycles with the assumption of maximum seating torque at stroke end and an average of 1/3 maximum seating torque during stroke.
Operating temperature
Actuators are suitable for operating under -30℃ to 70℃ambient temperature.
