Sensata Solid State Relays

Sensata, through its Crydom brand, has been the global leader in Solid State Switching technology for more than 45 years by offering the most extensive range of standard and custom solid state relays and contactors suitable for any load control application.

Sensata | Crydom has a broad offer of Solid State Relays and Contactors in several different mounting styles, covering a wide range of voltage and current ratings. Our Solid State Relays can be used to control almost any type of load in demanding heating, lighting, motion and power control applications that can benefit from the many advantages that SSRs have over traditional electromechanical relays, such as extended life expectancy, faster switching speed, lack of acoustical noise, higher resistance to shock and vibration, among others. 

Sensata’s Solid State Relays (SSRs) are versatile components utilized across various industries due to their reliability and efficiency. Common Industrial applications include:

  • Motion Control: SSRs are employed in systems such as conveyor belts, solar trackers, fans, solenoids, valve controls, elevators, lifts, hoists, and exercise equipment, providing precise and rapid switching capabilities.
  • Heating Control: They are integral to professional food equipment, plastic molding and extrusion machinery, HVAC&R systems, and soldering equipment, offering accurate temperature regulation.
  • Power Control: SSRs are used in power supplies, transformers, regulators, inverters, converters, and UPS systems, effectively managing power distribution and ensuring system stability.
  • Lighting Control: These relays are suitable for theatrical, warehouse, and commercial lighting applications, enabling efficient and silent operation.

Additionally, Sensata’s SSRs are ideal for controlling dynamic loads like motors, especially in applications requiring frequent start/stop cycles like Industrial Automation. Their long lifespan, quiet operation, and resistance to shock and vibration make them a preferred choice in demanding environments.

[WHITE PAPER] How Integrated Thermal Protection Technology Can Prevent Solid State Relay Failure in Industrial Systems

This white paper compares electromechanical and solid state relays for detecting overheating in electrical motors.

Large electrical motors are used in a wide range of equipment for industries and applications such as manufacturing, industrial and commercial HVAC, refrigeration, heavy duty transportation, medical, energy, assembly lines, and conveyor belts to name a few. An overheated motor can result in expensive damages; to avoid this, many companies using motor-driven machinery will invest in systems that sense overheating and turn the motor off. In most cases, these devices are electromechanical relays or solid state relays. For a long time, EMRs were the more common choice. This white paper compares the two and presents the advantages of choosing an SSR.

[WHITE PAPER] Selecting a Solid State Relay Or a Solid State Contactor For Start/Stop Control Of an AC Motor

This paper discusses the process that can be followed to select the correct Solid State Relay for motor control in those situations where Horsepower (HP) or Kilowatt (KW) ratings of the Solid State Relay may not be known or available.

Note: Solid State Relays (SSRs) and Solid State Contactors (SSCs) are essentially if not exactly, the same functionally. The differentiation between them is that by definition a “contactor” must carry a motor control rating in HP or KW, whereas a similar Solid State
