The Rockwell Automation 440G-LZS21SPLB is a Guardmaster Guard Locking Switch, part of the Guardmaster series, designed for safety applications. It is a power-to-release type switch, which means it locks the guard when the solenoid is energized and releases it when the solenoid is de-energized. This type of switch is commonly used in industrial settings to ensure the safety of personnel and equipment.
Technical Specifications
- Certifications and Compliance: The switch is CE marked for all applicable directives, UKCA marked for all applicable regulations, and cULus listed (UL 508). It also carries TÜV certification.
- Operating Voltage: The switch operates at 24V DC, with a tolerance of +10% to -15%.
- Current Consumption: The switch consumes 75 mA when the solenoid is not energized and no output load is present, and 120 mA when the solenoid is energized and no output load is present. The inrush current is 350 mA.
- Locking Force: The switch has a locking force of 1950 N (488 lb) for plastic pins and 2600 N (585 lb) for steel bolts.
- Operating Frequency: The switch operates at a frequency of 1 Hz, maximum, with a solenoid operating cycle.
- Response Time: The response time for the switch is 45 ms for the first switch and 10 ms for each additional switch in Series F and later models. For Series E and earlier models, the response time is 75 ms for the first switch and 25 ms for each additional switch.
- Environmental Conditions: The switch is designed to operate in environments with IP66, IP67, and IP69K ratings, which indicate protection against solid particles and water. It can withstand shock of 30 g and 11 ms, vibration of 10-55 Hz and 0.35 mm, and radio frequency interference according to IEC 61000-4-3 and IEC 61000-4-6 standards.
