What the IP66 and NEMA ratings mean on a wet line
The XCKJ562 carries IP66 and NEMA 1/2/4/12 enclosure ratings — it's sealed against hose-directed water and dust ingress, so it can sit on a filler turret or a washdown conveyor without the contacts corroding. The ZAMAK zinc-alloy body handles the mechanical abuse of a bottling or canning line — it's the same material used in die-cast valve bodies and pump housings in food plants.
Contact ratings — AC vs DC, the split matters
Rated 240 VAC at 10 A and 250 VDC at 0.27 A. The AC number is what you use for motor starters, solenoid valves, and relay coils; the DC number is derated because DC arcs don't self-extinguish at zero-crossing the way AC does. The SPDT slow make/break contact configuration gives you both NO and NC in one switch — useful for dual-channel safety circuits or for signaling both 'open' and 'closed' positions from a single actuator.
Actuator and mounting — roller plunger on a cam track
The plunger head with metal roller actuator is designed for cam-operated positions — the roller follows the cam profile without the sliding wear a plain plunger would see over millions of cycles.
Field wiring — PG13.5 gland, screw-clamp terminals
The PG13.5 cable gland entry accepts standard metric-armored or flexible conduit — no adapter needed for the panel knockouts common on European and North American machines. Screw-clamp terminals inside mean you land the wires with a standard slotted or Pozidriv driver — no crimp tool, no ferrule required for stranded wire up to the rating.
