SICK ZLM1-B1612E43 (7028843) – ZoneControl Sensor-Valve Assembly

SICK ZLM1-B1612E43 (7028843) – ZoneControl Sensor-Valve Assembly for ZPA

The SICK ZLM1-B1612E43 is a specialized Zone Control module designed for Zero Pressure Accumulation (ZPA) conveyor systems. This product is a plug-and-play multitasking device that eliminates the need for a central PLC by integrating a **Photoelectric Sensor** for product detection, internal control logic, and a **Pneumatic Solenoid Valve** for controlling the zone’s pneumatic stop mechanism. It is an ideal, decentralized solution for managing product traffic flow in complex conveying lines.

About This Zone Control Module

This module is the core component of SICK’s ZoneControl portfolio. It functions as a single accumulation zone controller, making the crucial GO/NO-GO decision based on the presence of a product in the next downstream zone. The integrated **Photoelectric Sensor** detects the object, and the onboard logic immediately actuates the **built-in Solenoid Valve**, which controls the compressed air to a pneumatic brake or diverter. The entire unit is designed for simple, side-frame mounting and features M12 connectors for quick daisy-chain wiring of up to 50 units, vastly simplifying system commissioning.
