Product Description

Product Overview

The Schmersal ZSR476E-02-1816 is a position switch with safety function belonging to the Z...476E series of lift switchgear. Designed for reliability and compliance in vertical transportation and lateral movement applications.

Standards Compliance

Complies with EN 60947-1, EN 60947-5-1, EN 81-20, and EN 81-50 standards, making it highly suitable for safety monitoring in elevators and lateral/rotating industrial operations.

Material & Protection

Features a glass fiber-reinforced thermoplastic shell with an IP65 protection rating under EN60529, providing superior dust and water splashing resistance.

Design & Installation

Designed with a locking function, low operating force, and a rotatable operating head (4 directions at 90° intervals). Equipped with three M20×1.5 cable entries.

Safety Contacts

Contains 2 normally closed (NC) break-before-make contacts with a spacing of 4×2mm. Each normally closed contact guarantees a forced disconnection force of 10N.

Switching Principle

Utilizes a bistable magnet quick-acting principle. Operating force is 3N (2N for straight rod plunger) with an operating speed of 0.5m/s.

Reset Mechanisms

Supports remote reset via reset voltage (Z..M 476E series, 230VAC / 24VDC) as well as manual reset using a reset rod (Z..R476E series).
