Omron Scientific Technologies, Inc: Safety Interlock Switch
The D4SL-N delivers simple installation and flexible operation in space-restricted door access applications.
Available with four, five or six contacts to satisfy varied application needs, the IP67-rated unit 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. Easy-to-view LED indicators allow users to quickly check switch status from any direction. The safety switches deliver a minimum of 1 million operations and boast a minimum key holding force of 1300 N to maximize the range of potential applications that can benefit from a tough, compact safety switch. The switches are available with two types of wiring: Connector-type wiring models feature a connector cable that reduces the potential for miswiring, facilitates fast maintenance, and allows easy switch replacement in the event a switch is damaged. Terminal block-type models include a detachable terminal block to significantly increase wiring efficiency.
