AIRON气缸SMT 系列 昆山德旭鼎进出口贸易有限公司
UNIVERSAL SENSOR ... "ONE FOR ALL"
During a design of pneumatic circuit, technicians use many actuators with different size, stroke and shape. Therefore, often there is the need to choose a specific magnetic sensor for each cylinder and this lead to an increasing effort to manage them in their stock. The universal sensor SMT.. is suitable on each AIRONs actuator .....(and not only AIRONs actuator).
HARSH WORK ENVIRONMENT SENSOR
Sensor range gives the right answer to any customer need in the pneumatic automation field.
"SMT" series sensor can be used on any AIRON actuators because they can be inserted in the standard T grooves and have been designed many brackets and bands to fit on tie rods and profiled barrel.
Following pictures clearly show the whole and complete use of that sensor on any tube or barrel.
For harsh work environment use, like frequent washing at high temperature and pressure, has been developed a specific sensor.
How to choose sensors
The magnetic switch is an electronic device which reveals the presence of a magnetic field.
Placed on magnetic cylinder it is mostly used as a proximity switch to open or to close an electric circuit.
AIRON proposes for its cylinder two kind of switches: Reed switch (electromechanical device) or Hall effect switch (electronic device).
Reed switch is avaiable with two or three leads circuit, allowing the second one the connection of more switches. This is due to the self electrical supplì of the led.
The electronic switch hasn’t mechanical devices therefore it gives the following advantages:
- longer life (109 cycles compared to 107 of the Reed version)；
- lower switching time；
- lower hysteresis；
- longer cables can be used (because the capacitive effect is lower).
The switches are fastened with related brackets properly shaped.
The use of protection device SMT.2PRO is suggested for Reed switches with 5m longer cable.
For harsh work environment (food, chemical etc. industries) AIRON proposes the SM6T.. switch.

2 Circuit with Reed switch normally open
Protected by a varistor against overvoltage caused when switching off, with indicator. Recommended circuit for most applications.
3 Circuit with Reed switch normally open
Indicator supplied by a third lead (black). Suitable for supplyng several switches in series as it eliminates the volage drop.
