The DMS-HA2-P is a compact, side-on optical data transmitter engineered for industrial automation, delivering 4-bit parallel I/O communication via 940nm infrared (IR) technology with ≤40ms half-duplex transmission speed . Designed for AGV-to-dock interfaces and semiconductor cleanrooms, it supports 3-meter range (±10° alignment tolerance), outperforming standard sensors like Keyence’s CX-411 (1.5m range) in extended-distance applications . Its pulse modulation and parity check error correction ensure reliable data integrity in high-noise environments, while the 10–30V DC power supply (≤100mA) enables energy-efficient operation in multi-device setups. Weighing just 280g (excluding cable), it mounts seamlessly on robotic arms or conveyor systems, with a 2m shielded 15-core M12 cable minimizing electromagnetic interference (EMI) .
Encased in an IP64-rated polycarbonate housing, the DMS-HA2-P withstands 10–55Hz vibrations (1.5mm double amplitude) and 501m/s² impacts, making it suitable for automotive assembly lines or outdoor logistics yards . Its -10°C to +50°C operating range and 4,000 lux ambient light tolerance (incandescent) surpass Sick’s OD Mini Pro (3,500 lux max) in challenging lighting conditions . The SEMI E84-compliant inch screw mounting ensures compatibility with semiconductor AMHS platforms, while the multi-color LED indicators (power, signal, error) streamline maintenance workflows. Unlike competitors requiring external logging modules, the DMS-HA2-P integrates built-in timestamped event logging for rapid troubleshooting .
The DMS-HA2-P supports teachable mode for parameter configuration via push-button controls, reducing setup time by 30% compared to potentiometer-adjusted sensors . Its half-duplex 2-way transmission and IP64-rated design enable seamless interoperability with HOKUYO’s passive receivers (e.g., DMS-HA2-R), ideal for space-constrained AGV systems. For applications requiring extended flexibility, HOKUYO offers the DMS-HA2-V variant (NPN output), while the DMS-HA2-P prioritizes PNP compatibility in legacy industrial setups . With RoHS-compliant construction and 5-year operational lifespan, it aligns with sustainability goals, outperforming competitors in reliability and adaptability.
