The Canfield Connector D5400 Series Micro Solenoid Driver is a NEMA 4 DIN Style “A” EN175301-803 (Formerly DIN 43650) and MINI type connector with a built in electronic circuit used to induce solenoid pull-in and reduce holding current. The time proven MSD has been designed into many applications where heat buildup occurs which reduces operating efficiency and life span of solenoid valves. The MSD has two main functions: one is to induce faster or stronger than usual response times at solenoid pull-in, the second is to reduce the net wattage of the solenoid during hold-in. The MSD drives the coil with a high input voltage for a fixed time period until the coil has shifted at which time the MSD reduces the holding voltage, which saves power, and the solenoid runs cool. The MSD Series is often used to replace low voltage power supplies where a 24 VDC solenoid valve can then be operated by 120 VAC. The Alternating current is rectified and the duty cycle reduced so as to operate the valve at proper voltage and wattage ranges. An additional advantage can be found when the MSD drops the holding voltage, which then reduces heat and current requirements.

A Micro Proportional Driver provides accurate control of hydraulic and pneumatic proportional solenoid valves used in mobile construction equipment and industrial processes. The MPD can control the flow of air or liquid linearly at a setting from 0.10-20 seconds. One example of use would be in a paint system. The MPD allows a solenoid to oscillate, significantly reducing system shock and wear commonly found in non-oscillation digital valve systems. The Micro Proportional Driver is a compact electronic circuit built into an environment-resistant miniaturized enclosure. The circuit features control of proportional solenoids and operators. Functions include minimum and maximum current limiting, control signals from 0-10V or 0-20 mA (with a step function at 0.2V or 0.4 mA included for minimum current), a 0.1-20 sec. linear ramp up/ramp down adjustment and output current proportional to input command signal.

The Canfield Connector B5950 Series is a rugged proportional driver built into an epoxy potted enclosure designed to control linear proportional solenoid operators. Features include selectable control signal inputs from 0-5V or 0-20 mA with adjustable min/max current output. The output steps to the minimum current setting when 0.1V or 0.4 mA is applied to the control signal input. Also included in the compact package is a 0.1 to 20 second adjustable ramp-up and ramp-down output and sine wave dithering (PWM) with adjustable amplitude and frequency. The B5950 has an output current that is proportional to the command signal input.
