▍Features
1.The product meets the strict requirements of the European Union's Restriction of Hazardous Substances (RoHS) directive.
2.Sealed to perfection and inherently safe, it's versatile and doesn't rely on a specific mounting position.
3.Built to withstand tough conditions, it operates flawlessly without allowing oxidation or contamination of its contacts.
4.Offering superior protection, it features high voltage isolation between open contacts and a contact chamber filled with inert gas.
5.Crafted with precision and quality in mind, the product's design and control measures align with the automotive industry's locally recognized lATF-16949 standards for excellence.
▍Coil Data
| Coil Voltage | Pickup Voltage | Dropout Voltage | Coil Resistance | Avg Holding Current | Holding Power |
| 12VDC | 9VDC Max | 1.2VDC Min | 26Ω | 461.5mA | 5.5W |
| 24VDC | 18VDC Max | 2.4VDC Min | 96.4Ω | 249mA | 6W |
| 48VDC | 36VDC Max | 4.8VDC Min | 392Ω | 122.5mA | 5.9W |
Remarks:
1. The coil parameter values are theoretical values at an ambient temperature of 20℃, with a variation range of approximately ±10% due to the influence of coil resistance.
2. The reliable working voltage range of the coil is 85%~110% of the rated voltage.
3. If other rated voltages are required, special orders can be made.
