12V Insulated Continuous Duty SPST Solenoid by Cole Hersee Model 24059

Description

Product Overview

The Cole Hersee 12V insulated continuous‑duty SPST solenoid (model 24059) is engineered for high‑reliability switching in demanding industrial environments. Constructed from machined steel, the housing provides exceptional resistance to corrosion, impact, and temperature extremes. The coil is wound with high‑temperature wire and terminated with steel 10‑32 threads, allowing secure connections using the included hex nuts and lock washers. Copper studs with a 5/16‑inch –24 thread pattern give a solid mechanical interface for mounting on panels or brackets. The solenoid’s 85 A normally‑open contacts deliver a single‑pole, single‑throw (SPST) function, making it ideal for applications that require a clean on/off operation without the need for complex wiring. With a compact footprint and a weight of only 12 ounces, the unit can be integrated into tight spaces while still providing the continuous‑duty performance required for long‑run operation. The design includes a protective coating that insulates the coil from external contaminants, extending service life and reducing maintenance costs.

Usage

This solenoid is suited for a wide range of industrial control scenarios. It excels in automation systems where precise timing and reliable actuation are critical, such as conveyor belt start/stop mechanisms, pneumatic valve control, and motor starter circuits. The 12 V rating aligns with common low‑voltage control panels, enabling seamless integration with existing power supplies and safety circuits. Its robust construction makes it appropriate for harsh environments, including manufacturing floors, processing plants, and outdoor installations where exposure to dust, moisture, and vibration is routine. The easy‑mount bracket holes (5/16‑Inch x 19/32‑Inch on 2 13/64‑Inch centers) allow quick attachment to standard DIN rails or custom frames, reducing installation time. Users in HVAC, water treatment, and material handling industries will find the solenoid’s reliable switching essential for maintaining system uptime and ensuring safe operation of critical equipment.

FAQ

What voltage range can this solenoid operate within?

The Cole Hersee 24059 is rated for a nominal 12 V DC supply. It can safely operate within a typical industrial control voltage tolerance of ±10 % (10.8 V to 13.2 V) without performance degradation.

Is the solenoid suitable for continuous‑duty applications?

Yes. The solenoid is specifically designed for continuous‑duty operation. Its coil is built with high‑temperature wire, and the insulated housing protects against heat buildup, allowing it to remain energized for extended periods without overheating.

How do I mount the solenoid on a control panel?

The unit includes bracket mounting holes spaced 5/16‑Inch x 19/32‑Inch on 2 13/64‑Inch centers. Use the supplied hex nuts and lock washers to secure the solenoid to a DIN rail, panel, or custom bracket. The copper studs provide a sturdy anchor point for wiring connections.

What type of contacts does this solenoid use?

It features 85 A normally‑open (NO) contacts in a single‑pole, single‑throw (SPST) configuration. This means the circuit is open when the coil is de‑energized and closes when power is applied, delivering a clean on/off function.

Can this solenoid be used in hazardous environments?

While the solenoid’s insulated housing offers protection against dust and moisture, for classified hazardous locations additional enclosure or certification may be required. Always consult local safety regulations and consider using an appropriate explosion‑proof housing if needed.
