Usually, when switching an inductive load by means of an induced voltage is produced by an intensive current change (di/dt), thus wearing the contact or malfunctioning the electronic circuit.
The Spark Quencher SQ is more compactly designed and low priced than the existing model.
We reccommend it to be used as main equipment in the RC network, being effective for protecting the contact and surpressing the noise.
Various types are available to meet a wide range of applications, NC machine tools, transportation machines, authomatic control machines, digital equipment, etc.
-
TF Type
For printed circuit boards, compact and inexpensive
-
BF Type
Extemely thin and space-saving design
-
NF Type
Miniature and space-saving design. Most popular and low-priced
-
SF Type
Compact construction using plastic film. Easy-to-use.
-
MF, MM Type
Able to mount directly to a coil of a magnet switch
MF: For products made by Fuji Electric
MM: For products made by Mitsubishi Electric
-
CF Type
For general control circuit and able to mount on DIN rail. Thin and space-saving
-
3F Type
Compact construction using plastic film for 3-phase. Most suitable for 3-phase induction motor.
-
3FR, 3FL, 3FC Type
Able to mount directly to thermal relay, wiring is unnecessary.
3FR: For products made by Fuji Electric
3FL: For large capacity thermal relay made by Fuji Electric
3FC: For products made by Mitsubishi Electric
