Schmersal Solenoid Interlock Switch 24V AC/DC, Power to Unlock, Coded Actuator, IP67, Plastic AZM170-02ZRI-B1 24VAC/DC

The Schmersal AZM170-02ZRI-B1 24VAC/DC Solenoid Interlock Switch combines advanced interlock technology with safety features for industrial machinery and automation. Operating on a 24V AC/DC supply, this switch provides power-to-unlock functionality, enabling safe access controls on machine guards, sliding doors and gates.

Security is enhanced with an individually coded actuator, preventing unauthorized or incorrect access. The actuator ensures that only the matching code triggers the unlocking mechanism, making the device tamperproof and well-suited for hazardous processes or areas. The glass fibre-reinforced thermoplastic housing resists impacts and heat, with self-extinguishing properties for added safety during fire exposure.

The switch is rated IP67, offering protection against dust ingress and water submersion up to 1 meter for half an hour, enabling installation in demanding environments. IDC (insulation-displacement contact) terminals simplify and secure electrical connections, while the M20 conduit entry supports standard industrial wiring practices.

With a high clamping force of 1000N, the AZM 170 series reliably keeps protective barriers closed even under substantial mechanical stress. It is rated for 1,000,000 mechanical operations, supporting intensive industrial use and reducing maintenance requirements. The device is equipped with two normally closed (NC) safety contacts, with a maximum contact current of 4A and an AC contact voltage up to 230V.

Its compact size (90mm length, 84mm width, 30mm depth) and durable construction make it ideal for integration into machinery frames and panel enclosures. Industrial applications include safeguarding sliding doors, machine gates, and automatic access points in factories and processing plants.

Secure interlocking and power-to-unlock operation protect users against hazards. Individually coded actuator ensures safety and compliance with tamperproof requirements. Plastic housing is impact-resistant, self-extinguishing and suitable for harsh settings.

IP67 rating allows installation in moisture-prone and dusty environments. High clamping force maintains closed barriers during operation. Long mechanical life reduces downtime in industrial automation. IDC terminals and M20 entry simplify installation and wiring in control panels.

Supports compliance with international safety standards.

Typical use cases include machine safety interlock for woodworking tools, metal processing lines and automated systems. The Schmersal brand is recognized for high safety and reliability standards in industrial automation.
