1. Product Overview
The Schmersal RS655-Z22-G115 is a heavy-duty safety limit switch engineered for extreme industrial environments requiring reliable position monitoring. Featuring a zinc die-cast housing with IP67/IP69K protection, this device incorporates a roller lever actuator (Z22) designed for high mechanical stress applications. The "G115" suffix indicates 115°C temperature resistance and enhanced chemical resistance for harsh conditions. Certified to ISO 13849-1 PL e (Category 4) and IEC 62061 SIL 3, it utilizes force-guided positively driven contacts that guarantee safe switching even during component failure. Operating at 24V DC with a mechanical life exceeding 2 million operations, its corrosion-resistant construction withstands aggressive washdowns, steam cleaning, and exposure to oils/coolants. The bright yellow actuator provides ±3mm lateral tolerance and visual position confirmation.
