AZM200 Solenoid Locking Switch - Thermoplastic Housing

Key Features

  • Solenoid locking design … controls access to hazardous areas until safe conditions exist.
  • Non-contact sensing … for long term reliability.
  • Dual purpose handle … unlatches and opens guard—no additional door handles are needed.
  • Integral LED diagnostics … indicates operating states
  • Integral self-monitoring and door detection sensors … satisfy requirements of PLe to EN ISO 13849-1 Safety Control Category 4 to EN 954-1. *See Note Below.
  • One-hand emergency release … hazardous area can be left quickly and safely—even during a power failure.
  • Switch and actuator do not protrude into door opening … no risk of injury or damage from a protruding actuator.
  • Dual PNP 250 mA safety outputs … for application versatility.
  • Designed for “daisy chaining”… up to 31 devices, max 200 m, can be wired in series without detriment to safety performance level.

The AZM 200 Series is designed for machine/work cells where access to a hazardous work area must be controlled until safe conditions exist. Their solenoid-latching feature permits locking a machine guard until dangerous conditions, which may exist immediately after removal of power, have abated. Solenoid-latching may be controlled by a time delay, motion detector, position sensor or other suitable component.

The AZM 200 consists of a solenoid-latching interlock and actuator unit with door handle and optional emergency exit handle. The actuator is always inserted into its housing, protecting the actuator and the operator against damage and injury. Utilizing pulse-echo sensor technology, the actuator and interlock can have an offset of ±5 mm and the actuator still engages the interlock.

Due to the one-hand operation of the emergency exit handle, the hazardous area can be left quickly and safely—even during a power failure (when using the “unlock by power” model). 

The solenoid interlock is a dual channel design with two short-circuit proof, safe PNP outputs, each of which can switch up to 250 mA.

With continuous internal function tests, the monitoring of the safety outputs and the use of door detection sensors, up to 31 AZM 200 solenoid interlocks can be wired in series without detriment to the safety performance level/control category (PLe to EN ISO 13849-1/Control Category 4 to EN 954-1).
