Safety interlock switches, up to 6 contacts
The D4SL-N Safety Interlock Switches by Omron STI is available with up to 6 contacts, can be mounted in any direction and allows users to change the key insertion point without detaching the head.
Omron Automation and Safety's D4SL-N Safety Interlock Switches are available with 4-, 5- or 6-contacts to satisfy many application needs. 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. Easy to view LED indicators allow users to quickly check switch status from any direction. D4SL-N 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.
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, 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.
6-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.

Annual Salary Survey
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
