440G-LZ Guard Locking Switch TÜV certified PLe Cat. 4 while using up to 60% less power Features and Benefits • TÜV certified to PLe, Cat. 4 (EN/ISO 13849-1), the highest level of safety for both door position and lock monitoring • An energy-efficient ‘green’ solution – uses up to 60 percent less power than competitive products • RFID standard(low) or uniquely(high) coded actuators provide application flexibility • High holding force of 1300N (Fzh tested to EN/ISO 14119) – suitable for a wide range of guarding applications. • Available in two models – Powerto-Release (safety of people) and Power-to-Lock (protection of machine production) • Two solid state OSSD outputs – connect in a series with other devices such as light curtains and SensaGuard Switches while maintaining PLe, Cat. 4 safety rating • Rugged IP69K-rated housing – ideal for food packaging and processing machines washdown requirements • Highly-visible 270° wrap-around LEDs provide status and diagnostics • Compact 45 mm housing with four actuator positions for flexibility of mounting • QR code on product links directly to on-line user manual The Allen-Bradley® Guardmaster® 440G-LZ from Rockwell Automation is a guard locking switch designed for partial body access guard doors. Combining microprocessor technology with an RFID coded actuator, the 440G-LZ features a locking bolt drive mechanism that will only lock when the correct actuator is detected. The locking bolt is continuously monitored for correct insertion within the actuator. This extra functionality allows the 440G-LZ to be certified PLe, Cat. 4 – the highest level of safety for guard door position and lock monitoring – and can be connected directly or in series with other PLe, Cat 4 rated safety devices. While the 440G-LZ provides this high safety performance level it consumes 60% less energy when compared to other guard locking switches, making it a truly “green” safety solution. It achieves this level of energy efficiency thanks to advanced algorithms and a bi-stable solenoid design that consumes little power for switching, regardless of whether in the locked or unlocked state. A great choice for global machine suppliers and end users, the 440G-LZ provides optimal application flexibility. The high 1300N holding force allows the switch to be used in a wide range of applications. Available in Power-to-Release and Power-to-Lock models, this switch can be used for personnel safety or the protection of machine production. RFID actuators can be ordered as standard- or uniquely-coded for flexible levels of tamper proofing. Plus, the hygienic and rugged IP69K-rated housing makes the 440G-LZ ideal for use in harsh washdown environments, such as those encountered in food processing and packaging applications. Easy to install, the 440G-LZ is designed in a compact 45 mm housing – sized for the most common guards – with four possible actuator orientations to allow for flexibility of mounting. Bright, 270° wrap-around LEDs provide status and diagnostic information for easy alignment and troubleshooting.
