KPX100 Weatherproof Dual Relay Keypad Access Control
Written by DENNIS ILIN on March 12, 2026

Weatherproof keypad access control systems are essential for managing secure entry at gates, doors, and controlled areas exposed to outdoor conditions. The KPX100 Weatherproof Dual Relay Keypad is engineered to provide reliable PIN-based authentication in high-traffic residential, commercial, and industrial environments. With its rugged stainless steel construction and durable metal keys, this keypad offers dependable performance in demanding installations.
Secure Outdoor Access for Gates and Doors
Access control installers and property managers often need systems that can operate outdoors while maintaining secure user authentication. The KPX100 addresses this need through a weather-resistant IP66-rated design that protects the keypad from dust, rain, and environmental exposure. Whether installed at an automated gate, building entrance, or parking barrier, the keypad ensures controlled access using secure PIN codes.
Its dual relay architecture allows the keypad to control multiple entry points or devices from a single unit. This flexibility makes it suitable for a wide variety of access control deployments, including gates, doors, and barrier arms.
Weatherproof Keypad Access Control for Gates and Doors
The KPX100 keypad access control system is designed to manage entry at outdoor locations where durability and reliability are essential. Featuring a rugged anodized steel housing and stainless steel faceplate, the device resists vandalism and harsh environmental conditions while maintaining consistent functionality.
The keypad includes backlit metal keys that improve usability in low-light conditions. This ensures users can easily enter PIN codes during nighttime operation or in poorly lit environments. High-traffic facilities such as gated communities, warehouses, and industrial sites benefit from durable keypads that maintain reliable operation even after years of frequent use.
Dual Relay Control for Flexible Access Management
One of the key advantages of the KPX100 keypad is its dual relay output configuration. Relay 1 supports up to 100 users, while Relay 2 supports up to 10 users, allowing administrators to control multiple entry points or access levels.
For example, one relay can control a main gate while the second relay manages pedestrian access or secondary entry points. This design provides flexibility for installations where different users require access to different areas.
Access Control Highlights
- Relay 1 supports up to 100 users
- Relay 2 supports up to 10 users
- NO / COM / NC contacts for integration with gate operators
- Ideal for multi-entry or multi-device control
The relay outputs integrate easily with gate automation systems, electric strikes, magnetic locks, and barrier arm controllers.
Durable Construction for Outdoor Security
Outdoor access control equipment must withstand environmental exposure, vandalism, and heavy daily use. The KPX100 features a 1.5 mm stainless steel faceplate combined with cast metal keypad buttons for long-term durability.
Its IP66 weatherproof rating ensures the device remains protected against rain, dust, and other outdoor conditions. Facilities installing keypad entry systems at gates, fences, and exterior doors benefit from this level of environmental protection.
Integration with Gate Automation and Entry Systems
The KPX100 is designed for seamless integration with automatic gate operators and access control systems. Its relay outputs allow the keypad to trigger gate motors, electric door strikes, or magnetic locks once a valid PIN code is entered.
Because the keypad operates on 12–24 VAC or DC power without requiring jumper adjustments, installers can connect the unit quickly and easily during installation. This simplifies deployment in both new installations and retrofit projects.
Installers frequently use keypad systems like the KPX100 in gate access control installations, where users need secure but convenient entry without requiring physical cards or key fobs.

- Residential community gate access
- Commercial parking gate control
- Industrial facility entry points
- Warehouse and logistics property gates
