Water, dirt, dust, mud, high shock and vibration are all the nemesis of “standard” solenoids when they are asked to perform over a broad range of environmental conditions. Extreme applications can include: 

•  Off-road vehicles

•  High dust factory and material handling environments

•  Agricultural machinery and irrigation systems

•  Marine and food service equipment

DURO-TECH® (D-T) solenoids from Magnet-Schultz of America (MSA) are the perfect response to customer demands for a robust, electro-mechanical linear actuators. The core of the DURO-TECH solenoid is a coil, which has admirably performed for many years in mobile Electro-Hydraulic systems. Designed and manufactured to meet an IP-65 minimum level of dust and moisture ingression protection, such coils inherently embody the key characteristics needed to survive extreme environments.

A well engineered use of neoprene boots and a purposeful design of the mechanical “guts” further ensure the DURO-TECH solenoid’s ability to survive extreme conditions.

DURO-TECH solenoid design and performance features
DURO-TECH solenoids are designed to operate in ambient temperatures from -40°C to + 50°C and are RoHS compliant. They’re NEMA (National Electrical Manufactures Association) insulation rated for Class H, 180°C maximum operation temperature.

MECHANICAL ATTRIBUTES:

• Direction of Operation: Push or a Pull mode

• Internal Spring: Returns the solenoid to the null position

• Protective Boots: Neoprene boots on each end prevent moisture and dust ingression to level IP-65, and retard the ingression of contaminants into the solenoid's core.

• Corrosion Protection: Plating on the external surfaces is Zinc Trivalent Chromate, suitable to meet 96 hours of a 5% salt spray environment. Epoxy Powder coating is available upon request for corrosion protection to 1,000 hours at 5% salt spray conditions

• Mounting Bracket: Rugged cradle style-mounting bracket, which is welded to the solenoid body

STANDARD BODY SIZES:

• 37 mm diameter x 50 mm length

• 45 mm diameter x 50 mm length

• 63 mm diameter x 72 mm length

ELECTRICAL CONSIDERATIONS:

• Electrical Connection

- Available with either integrated connectors and/or wire leads
- All options are molded into the coil for improved water and dust ingression protection
- Integrated connector styles include Deutsch, DIN, and METRI-Pack with the available connection style being dependent on the size of the D-T body

• Three Duty Cycle Variants

- Continuous Duty (100% on) operation
- Intermittent Duty (25% on, 75% off) operation
- Pulse Duty (10% on 90% off) operation

Additional dimensional information, including Force vs. Stroke capabilities are listed in the DURO-TECH brochure and on the MSA website.
