Allen‑Bradley 440N-Z21W1PB Non Contact Switch
Allen Bradley Guardmaster 440N Series Magnetic Non-Contact Safety Switch, 24V dc, Plastic Housing, 10m Cable
The 440N-Z21W1PB MC2 Magnetic Non-Contact Safety Switch by Allen Bradley Guardmaster ensures exceptional protection for equipment and machine operators. The MC2 switch is expertly designed to meet the risks of more complex modern safety guard monitoring applications.
This unit combines several magnetically sensitive elements which must be activated in a specific order to work correctly and allow the safety barrier to open. This improves guard door security and helps to decrease risk of injury to machine operators from hazardous equipment, minimising downtime.
The 440N-Z21W1PB MC2 safety switch has 2NC solid state relay safety outputs and 1xPNP auxiliary output, 0.2A max. It has a 10m cable and the supply voltage rating is 24 V dc. It features LED indication which allows quick and easy diagnostics and door status. This cost-effective switch is IP69K rated and is protected against ingress of dust particles and powerful jets of water, offering high reliability and durability. The operating distance is 10mm (make), 25mm (break). This unit has red housing to ensure high visibility of the switch.
The versatile sensor offers simple, effortless installation due to its small size and moulded-in brackets. For high-risk applications a control unit is used with a single sensor to provide a high-integrity system. For other applications, multiple sensors (including mechanical switches) can be connected.
