Product Overview
The Omron D4DS-K2 is a vertical-mount operation key — the metal tongue that inserts into the head of an Omron D4NS, D4NL, D4BL, or D4GL guard-lock safety-door switch. manufactured by Omron Corporation. Hengyixin Automation stocks this safety device in Xiamen and ships within 3-5 business days; safety-rated components ship with a batch-trace certificate.
It is not a switch itself: the actual switching logic, contact arrangement, and solenoid lock are inside the D4NS / D4NL / D4BL / D4GL body. The D4DS-K2 is the actuator that the switch detects.
The D4DS-K2 ships from Xiamen with full datasheet documentation. When the door closes, the key must fully enter the switch head with at least 4 mm of insertion margin so that door sag or misalignment does not cause a fault.
Key Features
- Insertion depth 20 mm min, overshoot tolerance 4 mm
- IP67 rating when mated with switch head
- Compatible with 4-contact D4NS and 5-contact D4NL switch heads
- Vertical-mount operation key for D4NS / D4NL / D4BL / D4GL switches
- SKU: D4DS-K2
- Series: D4DS (Operation Keys for D4NS / D4NL / D4BL)
Best-Fit Applications
- Top-inserted operation key on a robotic cell door swinging horizontally
- Vertical-mount operation key on a hinged guard door of a packaging machine
- Bottom-inserted operation key on a hinged access panel of an assembly cell
Buying Checklist
- Pick D4DS-K2 for vertical-mount key insertion; pick D4DS-K1 for horizontal-mount
- Pick D4DS-K2 when the door swing is horizontal and the switch is mounted above or below
- Pick D4DS-K5 if the mounting orientation is not yet decided

FAQ for D4DS-K2
Is the D4DS-K2 a switch or just a key?
The D4DS-K2 is the operation key only — the metal tongue that inserts into the switch head. The actual switching logic, contacts, and (if applicable) solenoid lock are in the D4NS, D4NL, D4BL, or D4GL switch body. The key is field-replaceable: a worn or damaged D4DS-K2 can be swapped without replacing the whole switch, which makes it the wear part, not the switch itself.
What's the difference between D4DS-K1, D4DS-K2, D4DS-K3, and D4DS-K5?
Four mounting orientations of the same key. D4DS-K1 = horizontal mounting (key inserts sideways into the switch). D4DS-K2 = vertical mounting (key inserts from above or below, this SKU). D4DS-K3 = adjustable mounting in the horizontal direction only. D4DS-K5 = adjustable mounting in horizontal or vertical direction (the most flexible). All four are mechanically and electrically compatible with the D4NS, D4NL, D4BL, and D4GL switch heads.
What switch holding force will I get with the D4DS-K2?
Holding force is determined by the switch, not the key. With a D4NL switch the holding force is 1,300 N min (the strongest). With a D4BL switch it is 700 N min. With a D4NS switch (no solenoid lock) the holding force is contact-block dependent, typically lower than 700 N. Pick the switch family based on the force your guard door requires; pick the key family (D4DS-K1/K2/K3/K5) based on the door's swing orientation.
Can I use the D4DS-K2 with a non-Omron switch?
The D4DS-K2 is dimensioned specifically for Omron D4NS, D4NL, D4BL, and D4GL heads. While some third-party safety-door switches share a similar mechanical interface, the exact key dimensions and insertion tolerances differ — using a D4DS-K2 in a non-Omron switch may cause incorrect contact actuation or premature wear. For non-Omron switches, use the key supplied with the switch or the manufacturer's listed cross-reference.
