Features
ESC is suitable for automatic control, PLC control circuit, etc.

● Lower power consumption type auxiliary relays and contactors with permanent magnets
● The best energy saving product for control circuits such as motor,automatic control and PLC circuits.
● Coil pick-up with a permanent magnetic field, less temperature rise and power consumption
● Less heat generation in coil (85℃→65℃)
● Low power consumption, high energy efficiency (9W→5W)
● 14.1mm, reduced depth compared to existing products.
● Coil polarity (+,-)
● CE marked, UL approval
