Product Description

Product Overview

The Festo ZSB-1/8-B (order number 576656) is a specialized pneumatic control block designed for two-hand start applications, focusing on operational safety and reliable performance in industrial automation. It integrates safety protection and pneumatic control functions, widely used in machinery and equipment requiring two-hand operation to prevent accidental activation. Below is a detailed breakdown:

Core Product Features

Safety-Certified Two-Hand Control: Complies with performance level PL c and category 1 safety standards. The two-hand control function ensures the machine can only start when both hands operate simultaneously, effectively avoiding personal injury caused by accidental triggering.
Explosion-Proof Adaptability: Certified for ATEX zones 1, 2, 21, and 22, with certification authorities including IFA 1201046 and Intertek UK-MCR-0080. It can operate stably in explosive environments, expanding application scenarios.
Stable Pneumatic Performance: Supports an operating pressure range of 0.4–0.8 MPa (4–8 bar) and a normalized nominal flow rate of 50 l/min (per DIN 1343). It is compatible with compressed air meeting ISO 8573-1:2010 [7:4:4] standards, ensuring smooth air flow and reliable control.
Durable & Versatile Design: The housing is anodized, with a die-cast aluminum cover and NBR seals, achieving CRC 1 low corrosion stress resistance. It supports any mounting position, with through-hole and internal thread mounting options for flexible installation.
Compliance & Environmental Adaptability: RoHS-compliant and meets LABS (PWIS) VDMA24364-B1/B2-L standards. It operates in an ambient temperature range of 0–60 °C and withstands severity level 2 shock tests (per FN 942017-5 and EN 60068-2-27), adapting to harsh industrial conditions.

Application Fields

Ideal for industrial machinery and automation equipment requiring safe two-hand operation, such as stamping machines, cutting equipment, assembly lines, and packaging machinery. It is especially suitable for scenarios in explosive environments (ATEX zones) or where high safety standards for operator protection are required.
