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.

Crydom’s signature family of solid state relays. Ratings from 10 A to 40 A @24-140 VAC, 12 A to 90 A @ 80-530 VAC and 10 A to 125 A @ 24-280 VAC – SCR output for heavy industrial loads – AC or DC control – zero voltage (resistive loads) or instantaneous turn-on (inductive loads) output.
- SCR output for heavy industrial loads
- UL/CSA/VDE Approved, CE Compliant to EN60950-1
With MOSFET output, this 1-DC Series Panel Mount DC output Solid State Relay offers reliable fast switching of DC loads through low On-State resistance. Power ratings for this DC output SSR range up to100 Amps at 100 VDC and 10 Amps at 500 VDC.
- High PWM switching capability (up to 5 kHz on selected models)
- UL approved, CE compliant to EN60950-1
- Epoxy-free design
CX & CMX PCB Mount Solid State Relays provide engineers smaller and more power-dense solutions for discrete or traditional panel-mount applications. This makes them prime targets for engineers who are trying to reduce the size of their overall system. Crydom PCB mount single-in-line packaged (SIP) solid state relays are an ideal alternative to discrete or traditional panel mount solutions. These highly functional SSRs provide quick, precise, and reliable switching – the perfect alternative for discrete or traditional panel mount solutions.
- SCR output for heavy industrial loads (CX)
- AC or DC control (CX)
- MOSFET output (CMX)
The DC60 Series are DC Solid State Relays with a cost effective bipolar transistor output in an industry standard panel mount package and ratings up to 7 Amps at 60 VDC.
- Ratings from 3A to 7A @ 60 VDC

[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.

This paper includes a summary review of three phase power systems, the characteristics of common three phase motor loads, and a comprehensive discussion of three phase SSRs and their application relative to such loads.
[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
