Omron's D4SL-N Safety Interlock Switches are available with 4, 5 or 6 contacts
Omron's D4SL-N Safety Interlock Switches are available with four, five or six contacts. The IP67-rated D4SL-N can be mounted in four different directions without needing to rotate the head. Two wiring methods minimize wiring time and make possible one-touch attachment and removal. LED indicators allow users to check switch status from any direction. D4SL-N safety switches are built to deliver a minimum of 1 million operations and offer a minimum key holding force of 1,300 N.
D4SL-N switches are available with two types of wiring. Connector-type wiring models feature a connector cable that reduces the potential for mis-wiring and allows switch replacement in the event a switch is damaged. Terminal block-type models include a detachable terminal block that is designed to increase wiring efficiency.
Six-contact versions of the D4SL-N safety switch enable users to independently monitor door open/closed status, as well as solenoid on/off status, from a single switch. An optional slide key prevents workers from becoming trapped inside the hazardous area, without having to use a padlock.
