In order to monitor the operating direction of a sliding gate (detecting movement to the right or to the left) using a single detector, the best solution is to use a 2-step limit switch.
There are many models of limit switch, but the standard low-cost model with IP66 degree of protection and an operating temperature between -25°C and + 70°C is available in the XCKJ range.
The best solution consists therefore in combining:
XCKJ for use at low and high temperatures
For an operating temperature up to - 40°C, use body part number: ZCKJ4046 (add H29 or H7 according to the cable entry).
For an operating temperature up to +120°C, use body part number: ZCKJ4045 (add H29 or H7 according to the cable entry).
Caution: For these non-standard temperatures of - 40°C and + 120°C, the operating heads are different to those used between -25°C and + 70°C (see catalogue).
