This is failsafe by design: loss of 24 VDC keeps the guard locked, so a wiring fault or power loss does not open the safety circuit on its own. The 6-contact array (3 NC + 2 NC/1 NO) routes the lock status and guard position to separate safety channels so a single contact failure cannot defeat the monitoring function. ## 24 VDC coil, indicator, and wiring fit Both the solenoid coil and the indicator lamp run at 24 VDC, so a single 24 V field supply powers the entire switch — no step-down or isolated bus needed. The terminal block connection accepts field wiring directly without a mating connector, which simplifies panel wiring on a DIN rail or subpanel but means conductor sizing and torque specs must match the terminal spec to maintain the IP rating of the assembly. ## M20 conduit entry and metal head for industrial enclosure fit The M20 conduit thread is the standard gland size for industrial enclosures in process and packaging automation — the matching gland clamps an armored or jacketed cable and seals the entry point. The metal head and standard metal release key suit panel environments where a plastic head would be a consumable failure point — repeated guard cycling in a high-cycle line chews plastic actuating heads faster than metal.","metaTitle":"Omron D4SL-N4QDA-D Guard Locking Switch, 1300 N","metaDescription":"Omron D4SL-N4QDA-D guard locking switch rated 1300 N holding force, 24 VDC solenoid, 6 contacts (3 NC + 2 NC/1 NO), M20 conduit, terminal block.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Limit Switches"],"specifications":{"title":"D4SL-N4QDA-D","Indicator":"Orange, 24 VDC","description":"D4SL-N Guard Locking Switch|Implement safe monitoring function with a wide range of models, holding force up to 1300N and different contact options","Conduit size":"M20","Head material":"Metal","lifecycle_stage":"mature","Release Key type":"Standard release key (metal)","Solenoid voltage":"24 VDC","Connection method":"Terminal Block","Key holding force":"1300 N","Number of contacts":"6","Contact Configuration":"3 NC + 2 NC / 1 NO","Door lock and release":"Mechanical lock/solenoid release"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$108.59","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/794e5f6e9775e095eba06ca72023f46a.pdf","sourceUrl":"https://automation.omron.com/en/us/products/family/d4sl-n"},"ai":{"faq":[{"question":"What is the contact configuration of D4SL-N4QDA-D?","answer":"Six contacts total: three NC (normally closed) plus a combined 2 NC/1 NO pole — this lets the safety controller monitor both guard lock status and guard position independently on separate safety channels."},{"question":"Where is the D4SL-N4QDA-D typically used?","answer":"Guard locking switches like the D4SL-N4QDA-D secure movable machine guards on packaging lines, presses, robotic work cells, and material handling equipment — the 1300 N holding force is sized for guard doors that must stay closed through the machine cycle, and the solenoid release lets the PLC sequence the unlock after the motion has fully stopped."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/omron/D4SL-N4QDA-D","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/omron/D4SL-N4QDA-D when reusing this data.
