- With exterior diaphragm
- plunger spacing 12 mm
- Upright housing, small flange
- Degree of protection IP67 according to IEC 60529
Exterior diaphragmThe exterior diaphragm protects the plunger guide against the entry of very fine dust (dust from grinding, casting, glass, etc.) and prevents the plunger seizing. At the same time, plunger sticking, caused by resinous lubricating coolants, can be prevented with this exterior diaphragm version. Switching elements
| ES 502 E | Snap-action switching contact 1 NC + 1 NO |
| ES 508 | Slow-action switching contact 1 NC |
On the usage of safety switching elements, the dog distance must be maintained to achieve the positively driven travel. The dogs must be positively mounted according to EN ISO 14119, i.e. riveted, welded or secured in some other way against becoming loose.
