Product DescriptionPhotoelectric sensors (photocell sensors) are
widely used in the gate and door industry. Door sensors are mainly
realized using microwave, infrared, or laser detection. Infrared
photoelectric sensors and infrared light curtains are most widely
used in industrial doors such as high-speed doors, roller shutter
doors, and sectional hard high-speed doors. When people
or objects are detected by the infrared device (photocell or light
curtain), no matter whether people move or not, as long as they are
within the detecting range of sensors and light curtains,
they will react and give the control output to protect people or
objects from being pinched. Microwave radar is also a widely-used
product in the automatic door industry. It responds to the movement
of people or objects, thus realizing the automatic door switch
control.PMF50R retro-reflective photoelectric sensor is one popular
model used in industry doors such as high-speed doors, roller
shutter doors, garage doors, and so on. Different detection ranges
can be selected as 7m, 12m,and Supply voltage 10-30V DC & 12-240V
DC/AC for selecting which can meet different demands of customers.

InstructionsCertifications The difference between the
normal version and the laser version of PF50R PF50R mirror
reflection type1. Aspherical optical lens to eliminate light
interference2. Easy to install, it can be fixed on the wall by
using the bracket3. One-piece design, can be used indoors and
outdoors PF50R laser mirror reflection type1. Narrow
beam design, more sensitive to sense objects2. The red laser makes
the process of installation simple and convenient3. Polarizer
design, no pressure to detect highly reflective objects
Product Installation & Maintenance Product installation:The
installation of the photoelectric sensor is relatively simple, as
long as the sensor is installed on the fixing frame, does not be
blocked by other things, and ensures the working state is
good.Product maintenance:Carry out regular inspections to check its
sensitivity and some relatively safe measures. The use of these
measures is also the most primitive function of our equipment for
protection. For the maintenance of the application switch, we still
have to do that we need to regularly Scrub or remove some dirt
because only in this way our switch will not have some problems
with sensitivity. Although the product has IP67-level protection
facilities, the product cannot be immersed in water for too
long. Therefore, when the product is used outdoors, be sure to
check the product after encountering heavy rain. Company
ProfileAbout G-TEK Sensor1Tianjin G-TEK Automation Technology Co.,
Ltd. was established in 2003, its main products are photoelectric
sensors and proximity sensors;2In 2004, the LST infrared vehicle
separator, also known as the infrared vehicle separating light
curtain independently developed by the company came on the market
and gradually occupied the domestic market of highway toll weighing
system3In 2009, the Haitai Green Industrial Park established
production and operation workshops, the same year a new generation
of intelligent defrost-type infrared vehicle separator LHA (C)
series curtain sensor came out, and was supported by the National
Innovation Fund4In 2013, further, expand the scale of production
and operation, and set up special workshops for the production of
sensor switches and vehicle separators light curtain sensors5In
2014, the research and development team and sales team of the
company are strengthened, the new research and development
production base project is launched, and Tianjin G-TEK Sensor
Technology Co., Ltd. is registered and established6In 2016, G-TEK
passed the certification of national high-tech enterprises, and the
construction of the new R&D and production base of G-TEK began
at the end of the same year7At the end of 2017, the first
long-distance, high-precision, and fast-sca
