Hikvision DS-K4H255S Magnetic Lock

High-Strength Electromagnetic Design

The DS-K4H255S utilizes advanced electromagnetic technology to create a powerful holding force:

• Maximum thrust capacity of 272 kg (600 Lbs) for secure door retention
• Special anti-residual magnetism design that eliminates lingering magnetic effects
• Pure electromagnetic suction operation for consistent performance
• Current interruption unlock method for immediate release when required

This powerful magnetic force ensures doors remain securely locked until authorized release, while the anti-residual magnetism technology allows for immediate disengagement when access is granted.

Versatile Installation Options

The DS-K4H255S is engineered for compatibility with various door materials and styles:

• Suitable for wooden doors of standard thickness
• Compatible with glass door installations
• Effective on metal door applications
• Includes necessary mounting hardware for different installation scenarios

This versatility makes the DS-K4H255S an ideal choice for diverse environments, from office buildings to retail spaces, educational facilities to healthcare settings.

Premium Construction Materials

Durability is a cornerstone of the DS-K4H255S design, featuring:

• Hard anodized aluminum shell with electroplating for superior wear resistance
• Eco-friendly zinc electroplating on the lock body for environmental responsibility
• Abrasion-proof materials throughout for extended service life
• Eco-friendly zinc electroplating on the armature plate for consistent appearance and durability

These quality materials ensure the DS-K4H255S maintains its appearance and functionality even in high-traffic environments where ordinary locks might show wear.

Flexible Power Configuration

The DS-K4H255S offers adaptable power options to suit various installation requirements:

• Dual voltage compatibility (12 VDC or 24 VDC)
• Default voltage setting of 12 VDC for standard installations
• Current draw of 470 mA at 12 VDC or 235 mA at 24 VDC
• Simple wiring configuration for easy connection to access control systems

This flexibility allows the DS-K4H255S to integrate seamlessly with existing electrical systems without requiring additional power adapters or converters.

Environmental Adaptability

Designed to function reliably across various environmental conditions:

• Operating temperature range from -10°C to 55°C (14°F to 131°F)
• Humidity tolerance from 0 to 95% relative humidity
• Maintenance-free operation in most indoor environments
• Durable construction that withstands daily use in commercial settings

The DS-K4H255S maintains consistent performance across seasonal temperature variations and in environments with fluctuating humidity levels.
