  • Contactors feature internal transorb for coil suppression. No external diodes should be added across the coil. The use of additional external coil suppression can slow the release time and invalidate the life cycle ratings, or can cause the contactor not to be able to interrupt the maximum current specified. If lower coil back EMF is required, please contact Sensata for assistance.
  • Applications with capacitors will require a pre-charge circuit.
  • Electrical life rating is based on resistive load with 27μH maximum inductance in circuit. Because your application may be different, we suggest you test the contactor in your circuit to verify life is as required.
  • End of life is defined as when the dielectric, insulation resistance or contact resistance fails the specifications listed.
  • Contact Sensata regarding DC Power Switching Cycle Life for part numbers that include auxiliary contacts. 1. Contact resistance measured at currents higher than 100A. 2. Operation time is measured at 25°C and includes maximum 7ms bounce. 3. Insulation resistance is 50 Mohms after life. 4. Contactor can operate up to 125°C in special cases - contact Sensata for details. 5. Contactor has two coils. Both are used for pick-up, and then in approximately 75 milliseconds, one coil is electronically removed from the coil drive circuit. The remaining coil supplies low continuous hold power sufficient for the contactor to meet all of its specified performance specifications. This provides low coil power without PWM electronics that can cause EMI emissions and/or cross-talk on control power. 6. Contactor is operated by a coil that changes resistance with temperature. Since pick-up current, coil current and coil power are specified at nominal voltage, they will be lower than indicated at temperatures above 25°C and higher than indicated at temperatures below 25°C. Similarly, pick-up and drop-out voltages will be higher than indicated at temperatures above 25°C and lower than indicated at temperatures below 25°C. 7. For pick-up testing of contactors with dual coils, the voltage can not be ramped up slowly, but must be applied instantly to at least the maximum pick-up voltage. Otherwise, the contactor will not pick-up. 8. Limit make current to avoid contact welding. Contact Sensata regarding DC Power Switching Cycle Life for part numbers that include auxiliary contacts. 9. Auxiliary contact rating is 2A, 24Vdc Resistive load, 100,000 cycles. Minimum current is 10mA, 5V . The auxiliary contact is mechanically linked to the main power contact*.
