Magnetic Proximity Switches
Memory type magnetic proximity switch for high temperature use PSMM-R3E1H (Large-Capacity Type)
▼Features
◼ It is a separate type proximity switch using Bestact for the built-in contact, which is hardly affected by environmental influences such as dust, gas, high temperature and high humidity, and has excellent contact reliability.
◼ These switches have a long track record as position detectors for cranes and trolleys in steel, chemical and cement manufacturing facilities, and contribute to the improvement of contact failure.
◼ No mechanical wear and long life due to non-contact drive using magnets.
◼ No power supply is required for the drive, making it economical.

Note: ＊1. Detectable distance at ambient temperature of +20℃ when both the switches and the magnet units are mounted on iron plates.
Setting gap where ambient temperature T (℃) can be calculated by the following equation. Setting gap (mm) =Rated sensitive distance
× {1-0.0018 (T-20) }
＊2. Values when the switch unit is mounted correctly on a non-magnetic material.
These values can decline depending on mounting of a magnetic material and mounting direction.
＊3. Only switch units are equipped with a cable.
