Frequently asked questions

How does the E1-M detect movement?
It uses 5.8 GHz microwave radar, not PIR technology. It detects movement within a 120° angle and an adjustable 0.5–5 m range, switches the connected lighting on and turns it off after 10, 30, 60, 180 or 300 seconds.
Can it be hidden behind furniture or a panel?
Yes. It detects through wood, plastic, glass and acrylic, with approximate penetration up to 50 mm through non-metallic materials. The Ø52 × 7 mm body mounts with 3M adhesive without drilling. Test detection through your actual material and thickness; avoid metal and concrete.
Which versions are available and how are they connected?
E1-M(D) has DC 5.5 × 2.1 mm connectors; E1-M(L) has 2-pin Dupont connectors. Both connect between a 5–24 V DC constant-voltage supply and a compatible LED load, observing polarity. Maximum 3 A: 15 W at 5 V, 36 W at 12 V and 72 W at 24 V. Never connect directly to 230 V.
Can it control lighting on stairs and in corridors?
Yes, it can switch compatible LED lighting when people pass through hotel, shop and clinic stairs or corridors. One sensor switches its entire load together; it does not control each step independently. Choose a 30–60 s delay for individual use. Keep multiple sensors at least 5 m apart to reduce interference. It does not replace emergency lighting.
Can it be used with LED panels in hotels, retail and clinics?
Yes, with 5–24 V DC constant-voltage LED panels, strips and assemblies within the 3 A limit. Suitable applications include retail displays, hotel furniture, clinic counters and circulation areas. It cannot directly control 230 V panels or luminaires requiring a constant-current driver. Set the switch-off delay to suit the space.

Invisible detection, no drilling

Built-in 5.8 GHz radar detects movement through wood, plastic, glass and acrylic, keeping the sensor out of sight. Switches on with movement and off after the chosen delay. Only 7 mm thick, 0.5–5 m range and 120° angle.

Surface mounting with 3M adhesive

E1-M adhesive surface mounting

Stick the sensor back to the panel with 3M adhesive and place the indicator sticker on the front. No drilling required.

Concealed installation behind a panel

E1-M concealed behind a non-metallic wooden panel

Stick the sensor face to the rear of the panel and place the indicator sticker in the corresponding front position. It detects through wood and non-metallic materials up to approximately 50 mm thick. Test the actual material and thickness. Avoid metal and concrete.

DC and Dupont wiring

E1-M(D) DC and E1-M(L) Dupont wiring

E1-M(D): 5–24 V DC constant-voltage supply → female DC input → sensor → male DC output → single-colour LED strip. E1-M(L): male Dupont input and female Dupont output, 2 pins, 2.54 mm pitch; 20 AWG cable, 50 cm each side. Marked wire positive, black wire negative.

Maximum 3 A: 15 W at 5 V, 36 W at 12 V and 72 W at 24 V. Disconnect power before wiring; never connect directly to 230 V.

Dimensions and applications

E1-M dimension drawing: 52 mm diameter and 7 mm thickness

Cabinets, display units, wardrobes, wine cabinets, corridors and stairs. Recommended wall height: 1.2–1.8 m; ceiling approximately 3 m. Keep sensors at least 5 m apart and avoid large metal objects or pipes facing them. Recommended delay: 30–60 s for individual or staircase use; 10 s for sequential lighting.

Individual switch application

E1-M sensor activating cabinet LED lighting when movement is detected

Set the switch-off delay to 30 or 60 seconds. The lighting turns on when movement is detected and switches off after the selected delay without further movement.

Multiple sensor application

Multiple E1-M sensors controlling LED corridor lighting

For installations with multiple sensors, set the switch-off delay of each sensor to 10 seconds. Each sensor activates its lighting when movement is detected, allowing the lights to switch on in succession as a person moves along the corridor. Keep sensors at least 5 metres apart to avoid mutual interference.

Staircase lighting application

Two E1-M sensors on a staircase: upper and lower sensors for up and down control

For staircases, install two sensors, one at the top and one at the bottom of the staircase. Set the switch-off delay of both to 30 or 60 seconds: the lighting switches on when going up or down and off automatically once the selected time passes without detecting movement.
