Product Description

The JA7A-JA7B Limit Switch is a robust industrial-grade device designed for precise position detection, featuring 2 digital inputs and 1 relay output, compatible with up to 4 modular units. It operates on 10-30V DC, supports RS-485 communication, and functions within -25°C to +85°C. Ideal for automation and machinery, the JA7B Compact Proximity model offers a 10mm detection range, encased in an IP67-rated housing for harsh environments. Meanwhile, the JD1A-JD1B Safety Relay provides fail-safe control with dual-channel redundancy, 3 safety-rated inputs, and 2 NO/NC outputs, directly interfacing with safety modules. It operates on 24V DC, tolerates -20°C to +55°C, and integrates with PROFIsafe or EtherCAT for real-time safety protocols in automotive or assembly lines. Both series emphasize compactness, durability, and compliance with IEC 60947-5-1/EN 60947-5-1 standards, though the JA7B’s limited sensing range and the JD1B’s higher cost may require application-specific evaluation.
