Proximity switches
series SP472 |
|
This proximity switch is designed for use in extreme temperature conditions. It can be placed and used in ambient temperatures from -40 to +150°C. This switch is suitable for use with cylinders to VDMA 24562 and DIN ISO 6431 when proper bracket is used. Switch is mounted to bracket with M3 screws (included in pack). |

Rules for using of proximity switches
WarningDo not exceed specification, permanent damage to the sensor may occur. |
1. | For reed switch type sensors, polarity must also be observed for the proper functioning of LED. Connect the brown wire in series with load positive (+) and the blue wire to negative (-) of power source. If the polarity is reversed, reed switch remains functional but LED will remain in “OFF” state. | |
|
||
2. | For solid-state type sensors , polarity must also be observed . Connect brown (red for SP-472 switch) wire to the positive (+) and the blue to the negative (-) of DC power source. The black (white for SP-472 switch) wire must connect to the load only. If the black (white for SP-472 switch) wire is accidentally connected to the power source, permanent damage to the sensor may occur. | |
NPN output switch type |
PNP output switch type

|
3. | An external protection circuit may be required if the reed switch is used with inductive load. For DC voltage, the diode must be connected, for AC voltage, the RC circuit must be connected as shown below. | |
DC power |
AC power R: 2,7kΩ C: 0,1µf/600V |
|
4. | Keep sensors away form stray magnetic field to prevent malfunctions. | |
5. | When using reed switch with capacitive load or if the lead wire length exceed 10 meters, an inductor must be installed in series. | |
