Full catalogue description: reed sensor magnetic switch applicable for position determination of pneumatic and/or hydraulic cylinder and piston pump D-SM2C
Typical applications
- Motor control centres and pump or fan starters
- Machine building, conveyors, packaging and CNC equipment
- HVAC control panels and building automation
- Water treatment, irrigation and pumping stations
- Panel retrofits replacing electromechanical control gear
How to specify the right Magnetic Sensor
- Size the contact rating for the inductive load, not just the resistive current (AC-3 duty for motors)
- Check the coil voltage and frequency available in the panel: 24 V DC, 110 V, 230 V or 400 V AC
- Confirm the auxiliary contact count needed for the control and indication circuit
- Match the enclosure rating to the environment (IP20 inside a panel, IP65 on the machine)

■舌簧传感器reed sensor
舌簧传感器又称磁性开关，适用于气动、液动、气缸和活塞泵的位置测定亦可作限位开关用。当磁性目标接近时，舌簧合经放大输出开关信号。与电感式传感器比
较有以下优点，能安装在金属中可并排紧密安装，可穿过金属进行检测。其检测离随检测体磁场的强弱的变化而变化。舌簧传感器不适用于强烈震动的场合。
Also called magnetic switch,reed sensor is applicable for position determination of pneumatic and/or hydraulic cylinder and piston pump.lt
also can be usedslinit switch. When the magnetic object approaches, the reed closes and sends out switch signal through magnificatio.
Compared with inductive sensor, it h tlie following strongpoints: can be installed in metal colsely and side by side and detect through met
al object. Its detection distance subjects to the intensity of magnetic field of detected object. Reed sensor is not applicable in the occasi
on of sevee vibration.
Model :D-SM2C
Size : 34*9*7*10
Frequently asked questions about the D-SM2C reed sensor magnetic switch applicable for
What is the difference between a contactor and a relay?
A contactor is built for switching power circuits repeatedly at high current, often with motor duty ratings (AC-3) and arc-suppressing chambers. A relay switches control signals at low current. In practice: contactor for the motor, relay in the control circuit that drives the contactor coil.
How do I calculate the correct contactor size for a motor?
Use the motor's full-load current, apply the AC-3 rating for the operating voltage, and allow for the number of starts per hour. As a rule of thumb, the contactor's AC-3 rating should be at least equal to the motor FLC, then step up one frame if the duty is heavy.
Do you supply the coil voltage I need?
Coil voltages are specified per order. Send the model number, coil voltage and frequency you require and we will confirm availability and lead time.
Are auxiliary contacts included?
Base models come with the standard auxiliary contact configuration for that frame. Add-on auxiliary blocks and mechanical interlocks can be quoted with the contactor.
