Sensata Crydom CX and CMX PCB Mount Solid State Relays

Sensata Crydom CX and CMX Series PCB mount Solid State Relays are designed for space-efficient integration with compact design and versatile performance. CX series are SIP-packaged relays with back-to-back SCR outputs, offering high surge-current capability and switching up to 5A at 660VAC. These relays support zero-crossing or instantaneous turn-on operation and are available with AC or DC control inputs.

The CMX series delivers efficient DC switching up to 20A at 200VDC using a MOSFET output stage in the same space-saving SIP footprint. CMX relays offer low on-state impedance and fast, reliable performance for precise DC control. The CX and CMX series support a variety of OEM, energy, HVAC, medical, and industrial automation applications.

As fun as big heavy electromechanical relays are, they can often be cumbersome and unreliable. For those who want a relay that can switch with some serious speed, the solid state CX & CMX Series PCB Relays from Sensta Crydom could be the relay for you. These relays come in a single in-line package, making them great for space-constrained applications, and their solid-state nature means that there are no internal moving parts. The CX range can be controlled via AC and DC voltages, have back to back SCR outputs for heavy industrial loads, and support both resistive and inductive loads with a maximum operating rating of 5A at 660VAC. The CMX range is DC controlled, has a MOSFET output, CE compliant to EN60950-1, and an operating rating of up to 20A and 200VDC. Finally, with an operating temperature range from -10°C to 80°C, these relays are perfect for industrial applications.
