1. Product Overview
The Schmersal TESZ1102/S/30 is a heavy-duty limit switch engineered for critical position sensing and safety interlocking in demanding industrial automation environments. Featuring a robust metal housing (typically zinc die-cast or high-strength plastic variant) and certified IP67 protection, this device reliably operates in harsh conditions involving dust, moisture, oils, and mechanical impacts. Its core function is to detect the presence, absence, or end position of moving machine components using a precisely engineered 30mm roller plunger actuator ("/30" suffix). This actuator incorporates a durable roller that minimizes wear during repeated contact with machine cams, levers, or moving parts. Built for safety-relevant applications where failure could lead to hazardous situations, the TESZ1102/S/30 utilizes force-guided contacts specifically designed to comply with essential safety standards. The standard "S" variant includes a corrosion-resistant threaded collar mounting design that provides flexibility for installation orientation and facilitates precise adjustment in confined spaces.
2. Key Technical Parameters
The TESZ1102/S/30 is designed for a standard control voltage of 24V DC to 230V AC (50/60 Hz), making it compatible with most industrial control systems. Its electrical core consists of Force-Guided Relays (FGR) configured as 1 NC (Normally Closed) + 1 NO (Normally Open) contact combination (rated at 10A / 250V AC, 6A / 400V AC, 2A / 250V DC). This FGR design ensures Positive Opening Action and complies with ISO 13849-1 Performance Level PL d (Category 3) and IEC 62061 SIL CL 2 requirements for safety applications. The 30mm stroke plunger (/30) features a robust roller tip ensuring smooth operation and long life exceeding 1 million mechanical cycles. Key environmental specs include an operating temperature range of -25°C to +85°C, high shock resistance (up to 100g), and vibration resistance (55Hz, amplitude 1mm). Standard cable connection utilizes M20 x 1.5 cable entries, while the housing material provides inherent chemical resistance against common industrial fluids.
3. Primary Applications and Use Cases
This heavy-duty limit switch finds essential application wherever precise end-position detection or safety monitoring of moving machine elements is required under challenging conditions. Common deployments include monitoring travel limits on material handling equipment (overhead cranes, gantry systems), automated transfer cars, palletizers, and heavy gates/doors. It serves as critical components within safety interlock circuits on guards, barriers, and automated guided vehicles (AGVs), preventing operation if protective devices are not properly positioned. The robust plunger design makes it ideal for detecting the position of machine slides, tables in metal forming presses, rolling mills, and woodworking machinery, where impact loads are significant. It’s also utilized extensively on mobile machinery (construction, agriculture) and mining/quarrying equipment due to its dust/water resistance and high shock tolerance. The FGR contacts are specifically employed in safety functions like confirming valve positions in hydraulic/pneumatic systems or verifying elevator landing door closure.
4. Product Advantages and Functional Benefits
The TESZ1102/S/30 delivers compelling advantages over standard limit switches. Its IP67-rated metal housing offers superior mechanical resilience and environmental protection, significantly reducing downtime and maintenance costs in harsh industrial settings. The 30mm roller plunger actuator provides long operational life and reliable switching even with misalignment or high lateral forces exerted by machine cams and levers. The integration of Force-Guided Relays (FGR) is a critical safety benefit, enabling its use in Category 3 safety circuits (PL d) by providing Positive Opening Action, high diagnostic coverage, and resistance to contact welding or failure modes that could lead to dangerous situations. Standard M20 cable gland entries facilitate quick, secure wiring installations. The threaded collar mounting allows for precise depth adjustment after installation to optimize actuation, saving significant setup time and ensuring reliable performance under thermal expansion or settling. Its wide voltage compatibility (24V DC to 230V AC) simplifies spare parts inventory.
5. Core Functionality and Safety Implementation
Functionally, the TESZ1102/S/30 operates by detecting physical displacement of its 30mm roller plunger actuator. When a machine component (e.g., a cam or moving part) contacts the roller, it pushes the plunger inward against a spring. This mechanical displacement directly actuates the internal switching mechanism. For standard position feedback, the NO contact closes and the NC contact opens upon actuation. Crucially, the force-guided mechanism ensures that all movable contacts are mechanically linked and move simultaneously. This design guarantees that if the NC contact welds in the closed position, the NO contact cannot close upon actuation, generating a detectable fault state. When used in safety applications monitoring guard positions or machine end-stops, this FGR characteristic is vital. The safety control system monitors both contact states. If an actuation occurs and the NC contact fails to open (or opens without actuation due to failure), or if the NO contact fails to close upon actuation, the safety PLC detects this discrepancy, triggering a safety shutdown or preventing machine start. This dual-channel monitoring forms the basis for achieving PL d safety performance. The plunger automatically returns to its rest position (causing the contacts to revert) when force is removed.
