Schmersal Z4V7H 335-11Z-M20-RMS | Metal Limit Switch, 1NO+1NC, Brass Roller Lever, M20×1.5, IP65/IP67
Schmersal Z4V7H 335-11Z-M20-RMS position/limit switch — metal housing, brass roller lever, 1NO+1NC snap-action contacts, AC-15 230V/4A, screw terminals M20×1.5, IP65/IP67, -30…+80°C. For machine position monitoring.
Product Overview
The Schmersal Z4V7H 335-11Z-M20-RMS is a heavy-duty electromechanical position/limit switch with a roller lever actuator (brass roller), designed for accurate position monitoring in demanding industrial environments. It features a light-alloy die-cast metal enclosure built to EN 50041 standard dimensions, a snap-action switching element with 1 normally-open (NO) + 1 normally-closed (NC) contact, and M20 × 1.5 screw terminals for secure wiring. The actuator head can be repositioned in 4 × 90° steps for flexible mounting orientation. With IP65/IP67 protection, 30 million mechanical operations service life, and oil/petroleum resistance, it is suited for conveyors, machine tools, and material handling equipment where reliable mechanical actuation is required. Complies with EN 60947-5-1, EN ISO 13849-1, and BG-GS-ET-15; approved CCC, cULus.

Key Features
-
Rugged Metal Housing (EN 50041): Light-alloy die-cast enclosure with standard dimensions — drop-in replacement for legacy EN 50041 limit switches; resists shock, vibration, oil, and petroleum.
-
Brass Roller Lever Actuator: Smooth, low-friction actuation with minimal wear — ideal for high-cycle cam or rail-driven applications.
-
Snap-Action 1NO+1NC Contacts: Constant contact pressure up to the switching point ensures reliable switching even at slow actuation speeds; simultaneous NO/NC signaling for position + safety feedback.
-
M20 × 1.5 Screw Terminals: Secure industrial-grade wiring with broad conductor range (0.75–2.5 mm²).
-
IP65/IP67 & Extended Temperature: Sealed against dust and water jets/temporary immersion; operates from -30 °C to +80 °C — suitable for indoor and sheltered outdoor installations.
Typical Applications
-
Conveyor & Material Handling: End-of-travel limits, diverter arm position feedback, belt alignment monitoring.
-
Machine Tools: Slide/home position detection, guard interlock feedback, tool carriage limits.
-
Packaging & Processing Machinery: Cam-follower actuation for rotary indexing, flap/gate position verification.
-
Heavy Engineering: Crane travel limits, hoist overtravel, and mechanical interlock duties where rugged metal enclosure is required.
