What does this pressure switch do?

This is an electromechanical pressure switch designed for monitoring hydraulic oil pressure and switching a control circuit when the set pressure thresholds are reached. It operates with an adjustable differential, making it suitable for regulation between two pressure points.

What pressure range can it be adjusted across?

The switching point on rising pressure is adjustable from 30 to 500 bar, while the switching point on falling pressure is adjustable from 7 to 447.4 bar. This gives the device flexibility for high-pressure hydraulic applications.

Is the differential adjustable?

Yes. The unit uses an adjustable differential scale, allowing the gap between the rising and falling switching points to be set to suit the application. The minimum differential is 23 bar at low setting and 52.6 bar at high setting, with a maximum differential of 300 bar.

Which fluid is it intended to monitor?

It is intended for hydraulic oil applications, with a controlled fluid temperature range of 0 to 160°C.

What type of pressure connection does it use?

The pressure connection is G 1/4 female, conforming to ISO 228. This is a common threaded connection style for hydraulic pressure devices.

What electrical contact arrangement does it have?

The switch features 1 changeover contact, also described as 1 C/O. This allows it to be used where a single pole needs to switch between normally open and normally closed states.

What type of electrical connector is fitted?

It uses a 4-pin male connector to EN 175301-803-A, formerly referred to as DIN 43650. This style is widely used on industrial sensing and switching devices.

Does it include a local display or scale?

Yes. The device includes a local display with an adjustable scale, which helps when setting the switching points directly on the unit.

What are the main electrical ratings?

The rated current is 3 A at AC-15, 120 V; 1.5 A at AC-15, 240 V; and 0.1 A at DC-13, 250 V. The rated insulation voltage is up to 500 V to IEC 60947-1, and the rated impulse withstand voltage is 6 kV.

What are the dimensions and weight?

The unit is approximately 113 mm high, 75 mm deep and 35 mm wide, with a net weight of about 0.78 kg.

What level of enclosure protection does it offer?

It is rated IP65, which means it offers protection against dust ingress and protection against water jets from any direction when correctly installed.

What operating temperatures can it handle?

The ambient operating temperature range is -25 to 70°C, and the storage temperature range is -40 to 70°C.

What materials are in contact with the fluid?

The wetted materials include stainless steel, brass, PTFE, steel, FPM and FKM. These materials are chosen to suit demanding hydraulic environments.

How durable is the switching mechanism?

The mechanical durability is rated at 3,000,000 cycles, and the device uses snap-action contacts for reliable switching performance.

Can it be mounted in any position?

Yes. This pressure switch is specified for operation in any mounting position, which can help when space or pipe layout is restricted.

What is the maximum pressure it can withstand?

The maximum permissible accidental pressure is 1125 bar, the maximum permissible pressure per cycle is 625 bar, and the stated destruction pressure is 2250 bar. For reference, these figures apply to the XMLB500D2C11 product specification.

What kind of pressure actuator does it use?

It uses a piston-type pressure actuator, which is well suited to high-pressure hydraulic sensing duties.

Which standards does it conform to?

The device is listed as conforming to CE, UL 508, CSA C22.2 No. 14 and IEC/EN 60947-5-1, making it suitable for a wide range of industrial panel and machine applications.
