Schmersal AZM 415-33ZPDK-24VAC DC Safety Switch

The Schmersal AZM 415-33ZPDK-24VAC/DC Safety Switch is a heavy‑duty solenoid interlock that locks two safety doors and provides fail‑safe access control in hazardous machinery. It features three safety contacts and three auxiliary contacts to monitor door status and interlock state, and it is designed for EN ISO 13849‑1 safety calculations with EN IEC 60947‑5‑1 compliance. The device accepts a 24 VAC or DC control supply and provides load ratings of up to 4 A at 230 VAC or 4 A at 24 VDC on its safety contacts, with an electromagnetically actuated mechanism that delivers a positive break travel of 4.5 mm and a minimum positive‑break force of 15 N. Latching force is adjustable from 80 to 400 N, and the switch is rated for up to 2,000 actuations per hour with a mechanical life exceeding 1,000,000 cycles. An aluminium housing with a factory‑applied finish and a screw‑terminal connection (M20 x 1.5) keeps wiring robust, with conductor ranges from 2 x 0.75 mm² up to 2 x 2.5 mm². The AZM 415‑33ZPDK is specified for operation from −25 °C to +80 °C and supports a two‑door configuration in typical installations. This model embodies the AZM 415 family’s design for reliable door interlocking in safety zones while meeting standards such as EN ISO 14119 and EN 60947‑5‑1.
