CL195 Series POM Black Angle Positioning Hinge with Stainless Steel Shaft (80° / 115° / 150°)

CL195 series are professional angle positioning hinges manufactured from high-strength POM engineering plastic with wear-resistant stainless steel pivot shaft. The core feature is the built-in angle stop mechanism that holds the door at a fixed opening position automatically, with three standard angle variants available: CL195-1 (80° stop), CL195-2 (115° stop) and CL195-3 (150° stop). Equipped with 4 symmetric mounting holes, lightweight, insulating, corrosion-resistant and low-noise, they are widely used for electrical control boxes, instrument enclosures, testing equipment casings, battery housings and industrial automation device covers.

1. POM Engineering Plastic Material Advantages

POM (Polyoxymethylene) engineering plastic features excellent mechanical strength, impact resistance, fatigue durability and self-lubricating properties. It is electrically insulating, non-conductive, and resistant to weak acids, alkalis, oils and common chemical solvents, will never rust like metal hinges. The lightweight plastic body reduces overall equipment weight and absorbs vibration during operation, eliminating metal collision noise for quiet opening and closing.

2. Stainless Steel Wear-Resistant Pivot Shaft

The central rotating shaft is made of solid stainless steel, greatly improving wear resistance and rotation smoothness. It effectively prevents plastic shaft abrasion, loosening and jamming after long-term repeated opening and closing cycles, significantly extending the overall service life of the hinge assembly.

3. Built-in Angle Positioning Mechanism

Core functional highlight: internal molded angle stop structure. Once the door opens to the preset angle (80°/115°/150°), it automatically locks and holds the position without external support. This positioning function prevents the door from falling back or swinging freely, allowing operators to inspect wiring, place samples or operate internal components with both hands free, greatly improving work safety and operational convenience.

4. Three Angle Options for Diverse Demands

Three standard stop angles cover most industrial application scenarios:

• CL195-1 (80°): For small compact cabinets and limited space installations, prevents door over-swing collision.
• CL195-2 (115°): Universal medium angle, suitable for most electrical boxes and instrument enclosures.
• CL195-3 (150°): Wide opening angle, ideal for equipment requiring full internal access and maintenance.

5. 4-Point Symmetric Stable Installation

Four evenly distributed Φ5.2 mounting holes ensure balanced stress distribution during opening and closing, preventing hinge deflection or screw loosening under long-term use. The flat mounting base fits closely to cabinet panels, suitable for plastic, aluminum alloy and thin steel plate enclosures.

Core Selling Points

1. Three Fixed Positioning Angles 80° / 115° / 150° options, auto-hold door position, hands-free operation for maintenance.
2. POM Engineering Plastic Body High strength, impact resistant, insulating, corrosion-proof, lightweight and low noise.
3. Stainless Steel Wear-Resistant Shaft Smooth rotation, durable for thousands of cycles, no plastic shaft abrasion.
4. 4-Point Symmetric Mounting Stable fixation, easy installation, compatible with various panel materials.
5. Cost-Effective Plastic Hinge Economical alternative to metal hinges for light-medium load equipment enclosures.

Typical Application Scenarios

1. Electrical control boxes, PLC junction boxes, sensor enclosures and automation device covers
2. Laboratory testing instruments, portable detection equipment and analytical device housings
3. Battery packs, power supply units, charging station plastic casings
4. Medical small equipment covers, clean room device panels and hygiene-grade enclosures
5. Plastic tool cases, handheld detection devices and industrial module cabinets

Installation & Selection Guidelines

1. Angle Selection: Choose 80° for tight spaces, 115° for general use, 150° for full access maintenance doors.
2. Screw Matching: Use M5 standard machine screws for Φ5.2 mounting holes for firm locking.
3. Load Range: Designed for light to medium weight plastic/ABS/PC door panels; not suitable for heavy large metal doors.
4. Environment Note: Avoid long-term high-temperature baking and strong corrosive liquid immersion to prevent POM material aging and deformation.
5. Quantity Suggestion: For wider door panels, install two CL195 hinges symmetrically for balanced load bearing.

Product Summary

CL195 series POM angle positioning hinges provide a cost-effective, lightweight and functional hinging solution for industrial equipment enclosures. With three fixed stop angles, durable POM plastic body, wear-resistant stainless steel shaft and stable 4-point mounting, they solve the pain point of doors falling back during operation, becoming an ideal standard hardware for electrical boxes, instrument enclosures and automation device covers.
