Guardian’s Explosion-Proof Solenoid is built for maximum safety and performance in hazardous environments. Designed with rugged, fully encapsulated construction, this solenoid meets stringent UL Class I, Division I, Groups A–D, ATEX, CSA, and IECEx hazardous location standards. With 30 lbs of force at zero stroke and a 54 lb holding force, it delivers reliable continuous-duty…
Guardian’s Long-life Tubular Solenoids are engineered for maximum durability and consistent performance in demanding environments. Each unit integrates an anti-bottoming ring and washer assembly to eliminate destructive impact forces, while a stainless-steel plunger sleeve and Teflon-coated plunger reduce friction and wear—dramatically extending mechanical life compared to standard thermoplastic designs. Ideal for continuous-duty or extended-cycle applications…
To maintain the highest level of quality Guardian manufactures the key components of every solenoid. We mold our own coil bobbins and wind our coils in-house. We have state-of-the-art machining capabilities for manufacturing all custom components. Our family of Solenoids includes custom wound coils and custom solenoid solutions including the design of value- added packages. We…
Guardian’s DC latching solenoids provide bistable actuation that holds position with zero continuous power—ideal for battery-powered, heat-sensitive, or duty-cycle-limited systems. Energize to latch; reverse polarity to release. The plunger seats to the pole face with a specified holding force and remains latched through power interruptions. Standard models are UL Recognized and RoHS-compliant (2011/65/EU), with rapid…
Economical AC and DC frame solenoids available in standard and heavy-duty pull/push models covering a wide range of forces and strokes. Plungers, voltages, spring returns, mounting, and terminations are easily customized, with value-added packages and build-to-print options. All catalog units are UL Recognized and RoHS (2011/65/EU) compliant, with datasheets and 3D models for fast integration—Made…
Guardian’s Laminated AC Solenoids are engineered for heavy-duty equipment that demands high force, high efficiency, and quiet operation. The T-shaped laminated plunger and laminated steel frame boost magnetic performance, delivering 25–50% greater pulling power and longer stroke versus comparable DC solenoids. For durability, the magnetic coil is fully encapsulated to shield against dust and moisture,…
Guardian Spring Kits are engineered to simplify spring selection and speed design cycles. Purpose-built for internal spring-return on standard Guardian solenoids, the kits bundle push and pull springs organized by color code to make force/length identification straightforward at the bench. Pick, test, and lock in the optimal spring without custom lead times—ideal for prototyping, tuning,…
Guardian’s tubular DC solenoids pack high force into compact tubes for valves, locks, latches and release mechanisms across aerospace, defense and heavy‑industrial systems. Standard diameters from 0.44 to 1.5 in (11–38 mm) deliver up to 40 oz [11 N] at strokes of 0.25–1.0 in, with push or pull action, continuous‑ or intermittent‑duty windings, and custom voltages from 6 to 48 VDC. Options include return springs, extended‑life bushings, hermetic or epoxy sealing, tailored lead‑wire terminations and value‑added subassemblies— all UL‑Recognized, RoHS‑compliant and 100 % made in our AS9100/ITAR‑certified U.S. facility.
