Product description

The Allen Bradley 440K-M2NANYC is a Guardmaster magnetic reed switch from the 440K series, designed for high-integrity safety applications. This non-contact switch is typically used to detect the presence or absence of a magnetic actuator, commonly mounted on sliding or hinged guards. Its non-contact operation reduces wear and tear, making it suitable for frequent actuation.

This type of safety switch is widely employed in industries requiring advanced machine safety, such as pharmaceutical manufacturing, cleanroom environments, and food processing where washdown or hygienic conditions are important. The 440K-M2NANYC is integrated into safety circuits to ensure that machinery cannot operate when guards are tampered with or removed, thereby enhancing worker protection.

Stanlo Automation, a veteran-owned surplus industrial automation parts supplier, offers the Allen Bradley 440K-M2NANYC. By providing access to these specialized safety components, we help businesses maintain compliance with safety standards and ensure the integrity of their safety systems, all while offering competitive pricing.
