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. This unit incorporates the DIN 43650 Form “A” / ISO 4400, EN175301-803:2000 connector male and female interface. The unit is mounted by use of a single mounting screw, DIN connector and two gaskets. Built to meet NEMA 4 environment standards, the MPD is made from engineered polymers for resistance to harsh chemicals and ingress of water or foreign substances. adjustments are made on the top surface of the unit. the unit can control any proportional solenoid valve operation within the values specified below using variable pulse width modulation.
The Canfield Connector Series D5400 Micro Solenoid Driver is a NEMA 4 DIN 43650 Form “A” / ISO 4400, EN175301-803:2000 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 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.
This Canfield Connector miniature timer makes any valve, with the DIN 43650 Form “A”/ISO 4400, EN175301-803:2000 electrical interface, able to operate as a compressed air system condensate removal valve. The unit installs in a modular form between an existing coil and connector. No new wiring is necessary. Retrofits on virtually any installation. It works with the valve brand of your choice. The cycle and on times are easily adjustable and two indicator lights show status.
The Canfield Connector micro logic timer is a solid state electronic timing unit incorporated inside the standard MINI and DIN 43650 Form “A” / ISO 4400, EN 175301- 803:2000 electrical connectors. The MLT allows precise timing and logic functions in a small, easily mounted enclosure. there are eight standard timer types. Each timer incorporates circuitry for AC or DC operation with a wide voltage range.
Canfield Connector FAC connectors are DIN 43650 Form A & C, Industry Standard Mini, and 9.4mm solenoid valve connectors that adapt connection from M12 and DIN 43650 Form A, Industry Standard Mini 7/8 Automotive standard inlet connectors. Made from the finest materials in the USA, these connectors mate with distribution boxes in a quick connect manner making assembly a snap. They are available in 3 or 5 Pin 7/8 Automotive, 4 or 5 Pin 12mm molded and wired, with or without indicator lights & surge suppression.
The FAC series connectors are modular interface connectors made to conform to industry standard configurations. These connectors interface female ISO, MINI and Sub-Micro solenoid connections to industry standard male 7/8″ (MINI) and 12mm (Micro) circular connectors. These are as shown on the following pages. These rugged modular connectors offer rapid installation and environmental protection designed to IP 65 and NEMA 4. Options include indication LED, surge suppression and various pre-wired circuit configurations to connect with popular multi-port electronic interconnection systems and field-bus systems.
The Canfield Connector DCP coil pin protectors are low cost replacements for solenoid connectors that ensure protection of solenoid terminals during shipping and handling. They can also be used to protect spade style terminals on a variety of other products. DCPs are available in a host of colors and styles as well as special logo markings to match the application. Constructed of low cost yet rugged polymers, the DCP adds aesthetic appeal and advertising value to the solenoid valve. There is a DCP available for ISO, industry standard MINI, Sub-Micro, and dual spade hydraulic coils.
