Retrieval Units with sensor
EH 22810.
For retrieve a workpiece on a seating element.
The retrieval unit is always built into a seating element as a single system. By means of a simple plug-in connection, it transmits whether a part is located at a specific position, as an electrical signal.
The retrieval unit can be used in combination with various seating elements. For example, the EH 22690 pins from the Halder standard parts are suitable.
Data is transferred via a cable connection. Optionally, the retrieval signal can be transferred by radio. The version with bushing must be used to connect the retrieval unit to the radio transmitter.
The retrieval unit meets the requirements of protection class IP6K7 (highly temperature-resistant and robust).

This product does not contain any substances designated as "conflict minerals" such as tantalum, tin, gold or tungsten from the Democratic Republic of Congo or adjacent countries.
How is the position of a component monitored by the retrieval unit?
The retrieval sensor contains a button that is operated by an overlying component.
Where is the retrieval sensor located?
The retrieval sensor is positioned on the outside of the body. The adjustable body allows the height to be set.
Which temperature ranges are allowed?
The sensor cable is designed to withstand temperatures of up to 180°C for short periods and is thus protected against chips, for example. The button can withstand temperatures of up to 120°C and is additionally protected against chips by the support of the workpiece.
How is the retrieval unit protected against dust and dirt?
Sensor (button): IP6K7, radio transmitter: IP67, radio receiver: IP20
Which seating elements can be used with the retrieval unit?
Seating elements with the following EH article number can be used: Size M8: 22690.0021 / .0121 / .0221 / .0321 / .0421 and 22691.0122 / .0021 / .0222. Size M12: 22690.0001 / .0002 / .0101 / .0102 / .0201 / .0202 / .0301 / .0302 / .0401 / .0402 and 22691.0143 / .0041 / .0042 / .0243
How to position the retrieval unit in the machine room?
The retrieval unit can be screwed into an M8 or M12 thread. The Halder base plate with slot tenons of the V40 or V70 system is suitable for this purpose.
How is the electrical power supply provided?
The radio transmitter is powered by an AA battery (3.6V) (not included in the scope of delivery). Depending on use, this battery lasts between 300 - 1400 days. The radio receiver has a supply interface: rated operating current/voltage Ie / Ue max. 0.1A / 24VDC -15%...+10%.
How is the retrieval signal transmitted wirelessly?
The electrical signal is converted into a radio signal by means of a radio transmitter and again into an electrical signal by the antenna of the radio receiver. Thus, the signal can be transmitted without having to lead a cable out of the engine room.
What kind of signals are transferred at the radio receiver?
Input: radio signal via antenna (frequency 868.3MHz). Output: electrical signal: 3A / 250VAC; 3A / 24VDC
What is the range of the radio signal?
The signal has a range of approx. 40m in closed rooms. In engine rooms, the range also depends on the type of cladding.
