SERIES AZM415DescriptionThe AZM415 Series is designed for movable machine guardswhere access to a hazardous work area must be controlleduntil safe conditions exist. Their solenoid-latching featurepermits locking a machine guard until dangerous conditions,which may exist immediately after removal of power, haveabated. Solenoid-latching may be controlled by a time-delay,motion detector, position sensor or other suitable component.Latching may occur upon energizing or de-energizing thesolenoid — depending upon model. In addition the AZM415features “positive-break” NC contacts, and an adjustable-forceball latch which maintains a holding force on the guard whenthe key is in the unlocked state.A two-key model is also available for guards which may beopen in two directions (Model AZM415-33zpdk).OperationThe AZM415 two-piece electromechanical safety interlockswitch consists of a rugged switch and solenoid-latchingmechanism and a geometrically-unique actuating key. Theswitch actuating key is typically mounted to a movablemachine guard.When the guard is closed, the actuator key is locked inposition by a toggle-lever system. The guard may only beopened by energizing or de-energizing (depending uponmodel) the solenoid-latching mechanism.Upon opening of the guard the switch’s “positive-break” NCcontacts are forced to open through a direct (non-resilient)mechanical linkage with the actuating key. The NO contactsclose upon key removal.Optional SafetyController.See Pages 84, 86,88 and 328.®Heavy-Duty Solenoid-LatchingSafety Interlock SwitchFeatures & Benefits• Solenoid-locking design … controls access to hazardousareas until safe conditions exist.• Highly tamper-resistant … difficult to defeat.• “Positive-break” NC contacts … assure circuit interruptionupon actuator key removal.• Watertight design … meets IP67 washdown requirements.• High-strength, metal actuator key … tolerates mechanicalabuse without damage.• Rugged, enamel-coated metal housing … tolerates themost hostile environments.• Adjustable actuator key holding force up to 110 pounds… permits use of switch as door latch.• Available in “solenoid-locking” and “solenoidunlocking”models … for application versatility.• Meets rigid safety agency standards … UL, CSA, IEC,BG and VDE.• Industrial-strength locking force … up to 560 pounds.• Patented toggle-lever locking system … facilitates easyunlocking of (even heavily misaligned) guards.• Two-key model … for double-sided guards (AZM415-33zpdk).• Optional B4 Actuator Key … prevents unintentional guardclosure.AVAILABLE STANDARD MODELS(Actuator key sold separately … see chart below)AZM415Switch insert S1 –solenoid position*Please specify solenoid operating voltage via addition of one of thefollowing suffix codes:VoltageAdd Suffix24VAC/DC -24VAC/DC120VAC-120VACACTUATING KEYS & ACCESSORIESDescriptionPart NumberLinear entry actuator key(For sliding lift-off guards)AZM415-B1Small radius (250mm) x-axis entry actuatorkey (For hinged guards)Small radius (250mm) y-radius entry actuatorkey (For hinged guards)Slide bolt actuator key (For sliding guards)Fail-to-Safe TimerXX / YY ZPKSwitch insert S2 –key position11(1 NO/1 NC)02(2 NC)Fail-to-Safe Standstill Monitor11(1 NO/1 NC)02 (2 NC)20 (2 NO)AZM415-B2AZM415-B3T(manualoverride)Leave blank(power to unlock)A(power to lock)AZ/AZM415-B4pSAZS2305 (Page 74)FWS1205B (Page 76)70®is a trademark of SCHMERSAL
