What the enclosure and contact ratings mean for a panel fit
The XCKML110 carries a NEMA 1/2/4/6/6P/12/13 and IP66 enclosure rating — the 6P designation means it withstands prolonged submersion and hose-down, so it fits on washdown stations or outdoor conveyor sections where a NEMA 12-only switch would weep. Contact rating is 240 VAC at 3 A and 250 VDC at 0.27 A — the DC rating is the limiting factor for inductive loads like small solenoid valves; the AC rating covers most pilot-duty control circuits in a panel. The SPDT 1NO-1NC double-break configuration gives you a normally-open and normally-closed set in one body, which simplifies wiring a safety circuit that needs both a positive-break NC feedback and a NO signal to the PLC.
Actuator kinematics and cam design constraints
Metal end plunger actuator with 2 mm pretravel, 1.2 mm differential travel, and 6 mm total travel — the pretravel tells you the plunger must depress at least 2 mm before the contacts transfer, and the differential means the reset point lags the operate point by 1.2 mm, which matters for cam lobe design where over-travel must stay within the 6 mm total. Operating force is 60 oz-inch — that is about 4.2 N at the plunger tip, so a light cam or slide can actuate it without needing a heavy spring return.
Compliance and approvals for cross-border panels
Applicable standards include EN/IEC 60204-1 (safety of machinery — electrical equipment) and EN/IEC 60947-5-1 (control circuit devices and switching elements), so it meets the machinery directive requirements for EU-market equipment.
Connection is via a 13 mm cable gland with screw clamp terminals — field wiring is straightforward with no special tooling, and the gland seals the cable entry to maintain the IP66 rating.
