ESPE safety door switches are used on fences of potentially dangerous machines and areas to monitor opening and closing of doors to ensure people safety protection.
SLE21 series is anelectromagnetic locking safety interlock switch, the misalignment constructure and strong holding force ensure an optimized solution for movable guarding doors.
The switch with advantage of electromagnetic and miniature size support new solution for small equipment with smaller inertia. Non-contact feature is available in high cleanliness and dust-freework shop like semiconductor, automobile manufacturing, beverage & food production etc.
